The Pioneer F-Series TS-F1634R are 6.5-inch 2-way coaxial car speakers designed for drivers seeking a simple audio upgrade without breaking the bank. With a standard size and a coaxial layout, they fit most factory locations and eliminate the need for separate tweeter mounting. Their 88dB sensitivity means they can produce clear sound even with a modest factory stereo, making them an ideal first upgrade for budget-conscious owners.
The 2-way design integrates a woofer and tweeter in one unit, which simplifies installation and ensures a cohesive soundstage. Rated at 200W peak (25W RMS) and 4-ohm impedance, they are compatible with most head units and small amplifiers. However, the low RMS rating suggests they are best suited for stock systems rather than high-powered setups that could push them to distortion.
While the product description highlights the speakers' power handling and sensitivity, it does not provide details on mounting depth, included accessories, or warranty. This means buyers must verify fitment with their specific vehicle make and model, as well as check if grilles or wiring adapters are included. Without these details, installation may require additional purchases.
Customer reviews are not available at this time, so long-term reliability and sound quality claims remain unverified. The manufacturer's specifications are a starting point, but real-world performance depends on the vehicle's acoustics and installation quality. For a budget upgrade, these speakers offer a reasonable value, but they are not a substitute for a high-end system.
Who should buy: drivers with a factory stereo who want a simple, affordable improvement in sound clarity. Who should avoid: those with high-power amplifiers or who demand premium build quality. Before buying, verify mounting depth, speaker size compatibility, and whether any adapters are needed.
Best Ownership Fit: These speakers suit a budget-conscious driver who wants a straightforward upgrade for a daily commuter or older vehicle with a factory stereo. They are ideal for someone comfortable with basic car audio installation or willing to hire a professional.
Daily Workflow: Once installed, the speakers operate passively with your existing head unit. You'll adjust volume and tone as usual, and the higher sensitivity should allow clear playback at moderate volumes without needing extra amplification.
Likely Friction: The main friction is fitment uncertainty. Without vehicle-specific compatibility data, you may need to remove door panels to check mounting depth and hole size, and you might need to buy adapters or spacers if your car's mounting points differ.
Before You Buy: Verify the speaker's mounting depth against your vehicle's door clearance. Check the cutout diameter and screw hole pattern. Confirm whether grilles, wiring harnesses, or mounting brackets are included. Also, consider the power output of your head unit to ensure it matches the 25W RMS rating.
Installation: These are standard 6.5-inch coaxial speakers, but installation steps will vary by vehicle. You'll likely need to remove the door panel, disconnect the factory speaker, and connect the new speaker's terminals. The product listing does not specify included hardware, so you may need to purchase screws, adapters, or wiring connectors separately.
Fitment Verification: Before installation, measure the mounting depth and cutout diameter of your existing speakers. Compare these to the TS-F1634R's dimensions, which are not fully provided in the product data. If in doubt, consult your vehicle's manual or a professional installer.
Maintenance: Car speakers generally require minimal upkeep. Keep the cones clean and dry, and avoid exposing them to excessive moisture. There are no user-serviceable parts, and the speaker's lifespan depends on usage and environmental conditions. If a speaker fails, replacement is the typical solution.
Warranty: The warranty terms are not mentioned in the product data. Contact Pioneer or the seller to confirm coverage before purchase.
Standard Size: These are 6.5-inch speakers, a common size in many vehicles. However, '6.5-inch' can vary slightly in cutout diameter and mounting depth across models.
Vehicle Fit: The product description claims they 'seamlessly integrate into most car interiors,' but this is a general statement. You must verify fitment for your specific car make, model, and year, as door panel depth and speaker mounting patterns differ.
Electrical Compatibility: With a 4-ohm impedance and 88dB sensitivity, they are compatible with most factory stereos. However, check your head unit's power output to ensure it can drive them adequately.
Included Hardware: The listing does not specify if mounting screws, grilles, or wiring adapters are included. Plan to purchase these if needed.
Pros
- Three-way coaxial design puts the woofer, midrange, and tweeter on one frame, so you get full-range coverage from a single speaker opening without adding crossovers or extra mounting locations.
- The 87dB sensitivity spec favors owners running factory or entry-level head unit power, since more of the available watts turn into actual volume.
- 6" x 9" is one of the most widely used factory sizes in American vehicles, which improves the odds of a straightforward rear-deck swap.
- 4-ohm impedance is the standard load for car audio, letting you connect to most head units or amplifiers without impedance matching headaches.
- The black and silver flush-mount styling suits visible rear-deck installations where the factory grille is removed or replaced.
Cons
- The 30W nominal rating is modest, so listeners who want high sustained volume or heavy low-end output will outrun these speakers and should look at a higher-power model paired with a subwoofer.
- Pioneer positions these as a passive design intended to be driven by an amplifier or receiver, which adds cost and labor for anyone hoping for a pure plug-and-play upgrade.
- The supplied product information does not list mounting depth, cutout dimensions, frequency response, or included hardware, so buyers with shallow rear decks or aftermarket adapters need to confirm fitment independently.
The Pioneer F-Series TS-F6935R is a 6" x 9" three-way coaxial car speaker aimed at drivers replacing worn or dull factory rear-deck speakers on a budget. It suits the owner of an older sedan, coupe, or truck who wants clearer vocals and better treble without redesigning the whole audio system. The qualification worth noting up front is the 30W nominal power handling, which sets a realistic ceiling on volume and bass output.
The three-way coaxial layout is the feature that matters most in daily use. Instead of asking one cone to reproduce everything, the design splits duties between a woofer, a midrange driver, and a tweeter mounted on the same frame. In practice, that tends to separate a singer's voice from the bass line and keeps hi-hats and string detail from smearing into the midrange. The 87dB sensitivity rating supports the same goal from a different angle, since a more efficient speaker converts more of the available power into sound. For someone running a factory head unit or a small four-channel amp, that efficiency is more useful than a large peak wattage number.
Physically, these are standard 6" x 9" units with a flush-mount profile and a black and silver finish, and Pioneer lists 4-ohm impedance, which is what nearly every car head unit and amplifier expects. The 6" x 9" footprint is the most common oval size in American vehicles, so the odds of matching an existing rear-deck opening are reasonable. Pioneer describes the speakers as a passive design meant to be driven by an external amplifier or AV receiver, and recommends professional installation unless you have wiring experience.
The limitations are real. A 30W nominal rating is not a lot of continuous power, so bass-heavy listeners who push volume will find the low end thins out before they run out of desire. There is no subwoofer here, and the supplied data does not include mounting depth, cutout size, frequency response, or hardware contents, all of which matter for a clean install. Anyone with a shallow rear deck should measure first.
Buy the TS-F6935R if you want an affordable, efficient step up from failing factory rear speakers and you listen at moderate levels. Hesitate if you are building a loud system, since the modest nominal power and lack of published depth specs make it a poor anchor for a high-output install. Those buyers should shop a higher-power component set plus a dedicated subwoofer instead.
Three-Way Coaxial Design: Pioneer stacks a woofer, a midrange driver, and a tweeter on a single chassis so one speaker opening covers low, mid, and high frequencies. The practical result is that vocals and cymbals get their own dedicated drivers rather than competing with bass on one cone. Drivers replacing muddy factory speakers benefit most, since clarity loss in aging paper cones usually shows up first in the midrange and treble.
87dB Sensitivity: Sensitivity describes how loud a speaker plays for a given amount of power. At 87dB, these convert modest input into usable volume, which matters if you are feeding them from a factory head unit or a small amplifier rather than a high-output stage. Efficiency-minded buyers get more listening level per watt, though sensitivity alone does not extend the speaker's power limit.
230W Peak and 30W Nominal Power Handling: The 230W figure is a short-term maximum, while 30W nominal reflects what the speaker is rated to handle continuously. The nominal number is the one to plan around when choosing an amplifier, because sustained power is what heats voice coils. Buyers matching these to a modest amp channel are well served; anyone shopping high-wattage amplification should size expectations accordingly.
4-Ohm Impedance: Four ohms is the standard load in car audio, so these connect to most head units and amplifiers without any special wiring or impedance matching. That keeps the install straightforward and reduces the risk of overloading an amplifier channel. It matters most to first-time installers who want predictable compatibility rather than another variable to research.
Flush-Mount Black and Silver Finish: The low-profile mounting style and two-tone appearance are aimed at installations where the speaker is visible, such as an exposed rear deck. Cosmetics rarely change sound quality, but they matter when passengers see the grilles daily. Owners removing damaged factory covers will appreciate a finished look without adding aftermarket trim rings.
Vehicle Fit: These use the standard 6" x 9" oval size, which is one of the most common factory speaker openings in American sedans, coupes, and many trucks, most often in the rear deck. If your vehicle already has 6" x 9" locations, the outline should be a close match. Verify against your specific year, make, and model before ordering, because the supplied product information does not include cutout dimensions or mounting depth.
Amplifier and Head Unit Pairing: With 4-ohm impedance and 87dB sensitivity, the TS-F6935R matches what most car head units and aftermarket amplifiers are designed to drive. Plan around the 30W nominal rating rather than the 230W peak when selecting an amp, since continuous power is what determines safe long-term operation. An entry-level four-channel amp or a capable head unit output is the natural pairing.
Passive Design Consequences: Pioneer describes these as passive speakers intended to be driven by an external amplifier or AV receiver, which means there is no built-in amplification. Budget accordingly if you do not already have an amp or a head unit with sufficient output. Buyers expecting a self-powered solution should factor in that extra component and the wiring work it requires.
Installation Considerations: Pioneer recommends professional installation unless you have car audio experience, mainly because wiring polarity, secure mounting, and correct fitment all affect the outcome. The supplied data does not list included brackets, grilles, wiring harnesses, or adapter plates, so assume you may need vehicle-specific mounting hardware. Anyone working with a shallow rear deck or a factory speaker adapter should confirm depth clearance first.
Best Use Case: These are a good fit for restoring clarity to a daily driver with tired factory rear speakers. The combination of three-way coverage and 87dB sensitivity is aimed at moderate-volume listening across podcasts, radio, and mixed music, where legible vocals and clean highs matter more than raw output. Commuters and older-vehicle owners get the clearest benefit from this kind of upgrade.
Where the Limits Show: With 30W nominal power handling, sustained high-volume playback is not the design target. Listeners who favor bass-heavy genres at loud levels will notice the low end running out of headroom before they reach their preferred volume. That group is better served by a higher-power speaker paired with a dedicated subwoofer, since a 6" x 9" coaxial alone cannot fill the sub-bass role.
Rear-Fill Versus Front-Stage Duty: Because 6" x 9" openings usually live in the rear deck, these most often serve as rear fill supporting a front stage. In that role, the dedicated tweeter and midrange help keep rear-seat listening clear rather than boomy. If your goal is a precise front soundstage with imaging in front of the driver, a component set with separately mounted tweeters is the more appropriate product type.
Realistic Expectations on Amplification: Pioneer's passive design means performance scales with the amplifier or receiver you pair with it, but only up to the nominal rating. Feeding these clean power within their limits will produce better results than pushing an underpowered head unit into clipping. First-time upgraders should prioritize clean, appropriately sized power over chasing the 230W peak figure on the box.

The BOSS Audio CH6530 is a 6.5-inch, 3-way car speaker pair designed for drivers who want a simple, low-cost upgrade from factory speakers. It suits budget-conscious owners of older vehicles or those who primarily listen to talk radio, podcasts, or background music. If you are looking for a cheap way to improve clarity and volume without adding an amplifier, these speakers are a reasonable starting point, but they have limitations in sound quality and power handling.
The most important features are the 3-way design, which includes a separate .50-inch piezo tweeter and a 1-inch polyimide dome midrange, alongside the main poly injection cone woofer. This configuration helps separate frequencies, potentially making vocals and high notes more distinct than a single-cone speaker. The rubber surround and poly cone are durable and resistant to moisture, which is beneficial for door-mounted speakers. With a sensitivity of 90 dB, they can produce decent volume from a factory stereo, even without an external amp.
In terms of design, the speakers have a stamped basket, which is a common budget construction that is lighter and less rigid than cast baskets. Mounting depth is 2.1 inches and the mounting hole is 5.5 inches, making them compatible with many standard 6.5-inch speaker locations. The pair weighs 1.3 pounds, so they are light and easy to handle. The 4-ohm impedance matches most car audio systems, and the frequency response spans 100 Hz to 18 kHz, which covers the typical audible range but misses some ultra-high frequencies.
However, there are meaningful drawbacks. The piezo tweeter is known for a bright, sometimes harsh sound at high volumes, which can be tiring for sensitive ears. The frequency response drops off above 18 kHz, so some airiness or sparkle in music may be lost. Also, the stamped basket may flex under heavy bass, causing distortion if you push them hard. For those who want deep, powerful bass, these speakers are not designed for that; a subwoofer or component system would be a better choice.
Overall, the BOSS Audio CH6530 is best for budget-minded buyers who want a simple, functional replacement for worn-out factory speakers, with the main benefit being affordability and ease of installation. The main reason to hesitate is if you prioritize sound quality, especially high-frequency detail or bass impact, in which case you should consider spending more on higher-end speakers. If you just need something that works and won't break the bank, these are a solid value.
3-Way Design: This speaker includes a woofer, a midrange, and a tweeter. The separate drivers handle different frequency ranges, which can produce clearer vocals and instruments compared to a single full-range speaker. It benefits listeners who want better separation between lows, mids, and highs without upgrading other components.
Poly Injection Cone: The main cone is made of polypropylene, a material that resists moisture and is lightweight. This helps the speaker withstand door-mounted conditions and reduces distortion at moderate volumes. It is a practical choice for daily drivers in varying climates.
Rubber Surround: The surround is the flexible ring around the cone. Rubber is more durable than foam and can handle temperature swings without cracking. This extends the speaker's life, especially in vehicles that experience extreme heat or cold.
.50-inch Piezo Tweeter: Piezo tweeters are known for being efficient and inexpensive. They can produce high frequencies clearly, but they can sound harsh or piercing at high volumes. This feature is a trade-off: it adds high-end detail but may not suit listeners who prefer a smoother treble.
1-inch Polyimide Dome Midrange: This driver handles the midrange frequencies, which include vocals and many instruments. Polyimide is a heat-resistant material, so it can handle power without degrading. It helps fill in the gap between the woofer and tweeter, improving overall balance.
90 dB Sensitivity: This rating indicates how efficiently the speaker converts power into sound. A 90 dB sensitivity means it can produce a decent volume level with a standard head unit, making it a good match for factory stereos that may not have a lot of power.

Confirm that your head unit or amplifier can handle the 4-ohm impedance (if applicable, though not specified). Ensure the included adapters match your vehicle's mounting pattern, or plan to modify the mounting holes.
Installation: The speakers come with multi-fit adapters to help with mounting, but the exact installation process is not detailed. You'll need to connect the speaker wires to your car's audio system, ensuring correct polarity. If you're not experienced, consider professional installation.
Compatibility: Verify that your vehicle's factory speaker wires are compatible. Check the impedance rating (not provided) to match your head unit or amplifier's requirements.
Maintenance: Car speakers generally require minimal maintenance. Keep them clean and dry to prevent damage. Avoid exposing them to excessive moisture or direct sunlight.
Replacement: If a speaker fails, you may need to replace it individually, but ensure the replacement matches the specifications of the other side.
Manufacturer Instructions: Since the product data does not include specific setup steps or warranty information, consult the manufacturer's manual or website for detailed installation guidance and care instructions.
Pros
- Budget-friendly price point makes it an accessible entry-level upgrade
- 3-way configuration adds a dedicated tweeter and midrange for clearer highs and mids
- High sensitivity ensures decent volume even with low-powered factory stereos
- Rubber surround and poly cone resist moisture and wear
- 3-year warranty provides peace of mind for a low-cost investment
Cons
- Limited frequency response (100 Hz - 15 kHz) means weak bass and no high-frequency sparkle
- Piezo tweeter can sound harsh at high volumes to some listeners
- Power handling is not specified, leaving uncertainty about durability under high power
The BOSS Audio Systems CH6530B 6.5-inch car speakers are a budget-friendly 3-way option designed for drivers seeking a simple upgrade from factory speakers without breaking the bank. With a price around $35, they offer a compelling value proposition for those who prioritize cost over audiophile performance. The strongest reason to consider them is their high sensitivity (90 dB), which means they can produce respectable volume even with a stock head unit, making them an easy drop-in replacement. However, their limited frequency response (100 Hz to 15 kHz) and lack of specified power handling are notable reservations for anyone expecting deep bass or high-volume headroom.
These speakers appear designed to serve the entry-level market, filling the gap for budget-conscious consumers who want improved clarity and separation over factory paper cones. The 3-way design incorporates a 0.5-inch piezo tweeter and a 1-inch polyimide dome midrange, which can enhance high-frequency detail and vocal presence compared to a standard coaxial. The poly injection cone and rubber surround are also practical choices for durability, resisting moisture and wear better than cheaper materials.
In terms of installation, the compact mounting depth (2.13 inches) and standard 5.5-inch mounting hole make them compatible with many vehicles, though professional installation is recommended to ensure proper fit and safe operation. The 3-year warranty is a strong point, especially at this price point, provided the purchase is made through Amazon.
However, the frequency response starting at 100 Hz means these speakers will not deliver substantial bass; they are best paired with a subwoofer if you crave low-end punch. Additionally, piezo tweeters are known for being bright and sometimes harsh at high volumes, which may not suit all listeners. If you listen to music with heavy bass or at high volumes, you might need to look at speakers with higher power handling and a broader frequency range, even if it means spending more.
In conclusion, the BOSS Audio CH6530B speakers are a reasonable choice for budget-minded buyers who want a simple upgrade for improved midrange and treble clarity. They are not for audiophiles or those seeking powerful bass. Before purchasing, verify your vehicle's speaker size and depth to ensure compatibility, and consider whether your listening habits will be satisfied by these limitations.
Strong Match: The clearest supported buyer is someone upgrading from blown or factory speakers in a car with a stock head unit, who wants a noticeable improvement in clarity and volume without spending much. The high sensitivity and 3-way design make these a practical choice for that scenario.
Also Consider It If: You are on a tight budget and prioritize a reputable brand name and a 3-year warranty over premium sound quality. These speakers offer a low-risk way to test an upgrade.
Not the Best Fit: If you listen to bass-heavy genres like hip-hop or EDM, or if you plan to amplify your speakers with an external amp, these will likely disappoint due to limited frequency response and unspecified power handling.
Decision in One Sentence: The BOSS Audio CH6530B is a fine budget pick for casual listeners who want a cheap, easy upgrade, but skip it if you need deep bass or high-volume performance.
Consider It For:
- Replacing factory speakers with a minimal budget.
- Getting a 3-way design with a dedicated tweeter and midrange for better high-end detail.

Pros
- Sized as a factory replacement at 6.5 inches, one of the most common diameters in American vehicles, which shortens install time for owners doing the work themselves.
- Coaxial two-way construction combines the tweeter and mid-bass driver in one basket, so you gain high-frequency output without drilling an A-pillar or fabricating a tweeter pod.
- The 360 watts maximum rating indicates these are built to accept more than a typical factory head unit delivers, which helps if an amplifier gets added later in the build.
- Comes from JBL's Grand Touring line, an established car audio series, so fitment references and owner discussion are generally easy to find when planning an installation.
- The included cleaning cloth is a small practical extra for cleaning dusty door trim and speaker grilles while the panels are already off.
Cons
- The 360 watts figure is maximum power, not continuous RMS, and no RMS number is provided in the supplied data, so buyers matching an amplifier need to verify JBL's published rating before setting gains.
- Mounting depth, sensitivity, and impedance are not listed here, which matters for shallow door cavities and for owners planning to run the speakers directly off a factory head unit.
- A 6.5-inch two-way coaxial has limited low-frequency output, so bass-focused listeners will still want a subwoofer, and anyone chasing precise stereo imaging may prefer a component set with separately positioned tweeters.
The JBL GTO629 is a 6.5-inch, two-way Grand Touring Series coaxial car speaker sold as a factory-sized replacement, which makes it a candidate for drivers swapping out tired original equipment speakers without rewiring or rebuilding door panels. It carries a 360 watts maximum power rating, though that is a peak figure rather than a continuous one.
Most of what this speaker changes in daily driving comes from the coaxial two-way layout. The tweeter sits on the same axis as the mid-bass driver, so a single unit covers highs and midrange from one factory opening, and there is no outboard crossover to find space for behind a trim panel. Compared with a worn single-cone factory speaker, the appeal is treble handled by a driver designed for it.
The size is the practical detail that decides whether this is an easy job. At 6.5 inches, it targets one of the most widely used speaker diameters in American cars, trucks, and SUVs, and the factory-sized replacement positioning points toward drop-in installation for vehicles already using that opening. The listing also bundles an Iron Crush cleaning cloth, which is a seller-added accessory rather than an audio component, handy for wiping grilles and door trim while everything is apart.
The limitations are worth weighing before ordering. Maximum wattage tells you little about how loud these will play on head unit power, and the supplied data does not include RMS power, sensitivity, impedance, or mounting depth, all of which affect amplifier matching and clearance behind door cards. Physics also applies: a 6.5-inch two-way will not deliver deep bass alone, and listeners who want a soundstage set at ear level are better served by components.
The strongest reason to consider the GTO629 is a low-friction upgrade path, replacing dull factory speakers in a standard 6.5-inch location with a name-brand coaxial. The main reason to hesitate is missing specification detail, since fit and power matching depend on numbers not shown in this listing. Buyers wanting deep bass, or a tuned front stage with separate tweeters, should look at a subwoofer or a component system instead.
Two-Way Coaxial Configuration: A two-way design splits the audio between a mid-bass cone and a tweeter, with both mounted on a shared axis. That solves the biggest weakness of aging single-cone factory speakers, which tend to sound muffled at the top end. It benefits owners who want fuller sound but do not want to run new wiring or find a legal, rattle-free spot for a separate tweeter.
6.5-Inch Factory-Sized Format: The 6.5-inch diameter matches one of the most common original speaker sizes used across American vehicles. For the installer, that usually means reusing the existing hole pattern and grille rather than cutting sheet metal or fabricating baffles. The buyer who gains the most is someone doing a weekend swap with basic tools and no interest in custom work.
360 Watts Maximum Power Rating: Maximum power describes short peaks the speaker is rated to survive, not the continuous power it wants. Practically, a high peak number suggests the speaker is not designed only for weak factory head unit output and can grow into an amplifier later. Anyone actually sizing an amp should work from JBL's continuous RMS rating instead, which this listing does not state.
Grand Touring Series Positioning: The GTO line is JBL's long-running car speaker family, and buying into a known series has practical value beyond the badge. Fitment references, replacement parts, and owner experience are easier to research than with unbranded speakers sold under rotating listings. That matters most to first-time installers who want to confirm compatibility before committing to the job.
Included Iron Crush Cleaning Cloth: The bundled cloth is an accessory added to the listing rather than an audio upgrade. It has a modest but real use during installation, since door cards, grilles, and window switches collect dust that is easiest to clean while the panel is removed. Treat it as a minor convenience item and not as a reason to choose these speakers over another pair.
Vehicle Fit: These are intended for vehicles that already use a 6.5-inch speaker location, typically front doors, rear doors, or rear decks. If your car came with 6x9, 5.25-inch, or oval factory speakers, this is not a direct swap without adapter brackets. Check your specific year, make, model, and trim before ordering, since speaker sizes often vary between base and premium audio packages in the same vehicle.
Power Source: The supplied data lists maximum power only, with no continuous RMS rating, sensitivity, or impedance. Those three numbers determine how the speaker behaves on factory head unit power and what amplifier suits it. Verify them on JBL's published specification sheet if you plan to drive these with an aftermarket amp, or if your factory system already runs an amplified premium audio setup.
Wiring and Mounting Hardware: No mounting hardware, brackets, or wiring harness adapters are listed in this product data, so plan on sourcing vehicle-specific speaker harness adapters and mounting brackets separately if your car needs them. Many installations also go smoother with foam or closed-cell gaskets to seal the speaker to the door, though nothing of that sort is confirmed as included here.
Depth and Grille Clearance: Mounting depth is the most common cause of a failed 6.5-inch swap, because window glass, regulators, and door skins can sit close behind the factory opening. Since a depth figure is not provided in this listing, measure the available space in your door before buying, especially in compact cars and vehicles with frameless windows that drop fully into the door.
When to Pause: If your vehicle uses digital signal processing, a factory amplifier with equalization curves baked in, or speaker-level fault detection, a straight coaxial swap can behave unpredictably. Owners of those systems should research their platform first rather than assuming a factory-sized replacement will integrate cleanly.
Best For: Drivers with a stock or lightly modified system who want a noticeable improvement over worn factory speakers in a standard 6.5-inch location, without committing to a full audio build. It also suits used-car buyers restoring an older vehicle where original speakers have dried out or blown, and DIY installers who want a recognizable brand with predictable fitment references.
Consider Alternatives If: You want deep bass, in which case a subwoofer does far more than any 6.5-inch coaxial. You want a defined front soundstage, in which case a component set with tweeters mounted higher in the cabin is the better structure. You have a factory premium audio system with a dedicated amplifier and DSP tuning, where a component-level upgrade or a system approach usually integrates better than a single coaxial swap.
Setup and Daily Use: Expect a typical door speaker replacement workflow: remove the interior panel, unbolt the factory speaker, connect the new speaker using an appropriate harness adapter, mount it in the existing opening, and reassemble. After installation there is nothing to operate or configure on the speaker itself, since level and tone stay under the control of the head unit or amplifier. Anyone adding an amp later should set gains conservatively using JBL's continuous power specification.
What Sets It Apart: Compared with generic factory-replacement coaxials, the draw here is the JBL Grand Touring name and a high peak power rating that signals room to grow into an amplified setup. Compared with component systems, the trade-off is straightforward: less installation work and no crossover placement to solve, at the cost of tweeter positioning and imaging control. Choose based on how much of the door you are willing to take apart and how much tuning you actually want.
Pros
- Shallow depth and included hardware reduce installation friction for DIYers
- High sensitivity (92 dB) means efficient performance from factory head units
- Wide frequency response (35Hz-22kHz) covers full audio spectrum
- 4-ohm impedance matches most factory systems
- Durable materials (ABS composite grills, rubber/cloth diaphragm) support long-term use
Cons
- No verified customer reviews yet, so real-world durability and sound quality are unconfirmed
- Exact vehicle fitment not specified; you must measure depth and mounting holes before buying
- RMS power rating (30W) is modest, so they may not satisfy users seeking high-volume output
The JVC CS-J620 6.5" 2-way coaxial car speakers are designed for drivers who want to upgrade their factory audio without major modifications. With a shallow top mount depth of 1-23/32 inches and pre-arranged mounting holes, they are engineered to fit many vehicles while avoiding window tracks and other door obstacles. The included wire extension cables, screws, and mounting tabs further support installation, making them a practical choice for DIY enthusiasts.
In daily use, the mica cone woofer and 1-inch PEI tweeter provide clear high-range and smooth mid-range audio, while the 92 dB sensitivity helps them perform efficiently even with lower-powered factory head units. The 4-ohm impedance and 35Hz-22kHz frequency response cover a broad range of music genres. The rubber and cloth diaphragm and ABS composite grills are built to withstand the rigors of daily driving, but real-world durability is not yet confirmed by customer reviews.
One notable friction point is the lack of verified customer feedback, so long-term reliability and actual sound quality remain open questions. Additionally, while the shallow depth aids fitment, you must still verify that the speakers match your vehicle's mounting holes and depth requirements. The 30W RMS power handling is modest, so if you enjoy high-volume listening, you may need to consider more powerful alternatives.
These speakers are best for drivers seeking a budget-friendly, straightforward upgrade with easy installation and improved audio clarity over stock speakers. They are less suited for audiophiles or those needing high power handling. Before purchasing, confirm your vehicle's speaker size (6.5 inches), mounting depth, and hole pattern, and consider checking your car's speaker impedance compatibility.
Best Ownership Fit: This set suits DIY car owners who want to replace worn factory speakers with minimal hassle, especially those with average mechanical skill and a standard 6.5-inch speaker opening.
Daily Workflow: After installation, you'll enjoy improved sound during commutes or road trips. The speakers are passive, so no routine operation is needed beyond using your car's stereo controls.
Likely Friction: The biggest unknown is whether the speakers will fit your specific vehicle without extra modification, as the manufacturer doesn't list a fitment guide. Also, the modest power handling may limit volume levels.
Before You Buy: Verify your car's speaker size, mounting depth, and hole pattern against the JVC's 1-23/32" depth and pre-arranged holes. Confirm that your stereo's output power (RMS) is compatible with the 30W RMS rating per speaker. Check if any additional adapters or harnesses are needed for your vehicle. Note that the included hardware covers some modifications, but you may still need to purchase brackets or wiring adapters.
Installation: The speakers come with wire extension cables, screws, and mounting tabs to assist with installation. The shallow depth and pre-arranged holes are designed to simplify mounting, but you must ensure the speaker fits your vehicle's door or rear deck. If your vehicle requires custom brackets, you may need to fabricate or purchase them separately.
Wiring: The included extension cables help connect the speakers to your existing wiring. Ensure proper polarity (positive to positive, negative to negative) for correct sound phase. If you're unsure about wiring, consult a professional.
Maintenance: The speakers are designed to be maintenance-free. To keep them performing well, avoid exposing them to excessive moisture or dirt. Periodically check the mounting screws to ensure they remain tight, especially after installation.
Replacement Parts: No consumables or replacement parts are specified. If a speaker fails, you would likely need to replace the entire unit.
Verification Needed: Since detailed installation instructions are not provided, confirm mounting depth, hole pattern, and wiring compatibility with your vehicle's make and model. Contact JVC support or consult a car audio professional if you have any doubts.
Pros
- The stated 90 dB sensitivity suggests the pair is intended to reach usable volume from a low powered factory or entry level head unit, which matters to buyers who do not plan to add an amplifier. This is a manufacturer figure, not an independent measurement.
- A 1-11/16 in. top-mount depth is shallow for a 6.5 in. coaxial, improving the odds of clearing window glass, regulators, and door hardware in tight factory openings, subject to your own measurement of the specific door.
- The 4-7/8 in. cutout follows the common pattern for 6.5 in. openings, so many vehicles will accept them in the factory location or with an adapter bracket, though the listing does not confirm any specific vehicle fitment.
- The 4 ohm impedance is the standard load for factory head units and typical aftermarket receivers, reducing the chance of a mismatch when reusing existing speaker wiring.
- Construction is disclosed rather than vague: polypropylene cone, treated cloth surround, ferrite magnet motor, and a 1 in. balanced dome tweeter. Treat these as specifications for comparison shopping, not as evidence of durability or tonal quality.
Cons
- Continuous power is quoted as 60 watts RMS per pair, so each speaker handles only a fraction of the headline 300 watt peak number, and no per-speaker RMS figure is supplied. Buyers planning a dedicated amplifier with real headroom should compare against speakers that publish per-speaker continuous ratings.
- The 40 to 22000 Hz frequency response is given without a tolerance window or test conditions, so it cannot be read as usable low end output from a door location. Anyone expecting deep bass should budget for a subwoofer instead of assuming the 40 Hz figure translates to the vehicle.
- No review excerpts, complete model code, warranty terms, or statement about included grilles, mounting hardware, and wiring adapters were supplied, which leaves owner experience, exact model cross-referencing, and installation completeness unverified.
The product under review is a Kenwood 6.5 in. two-way coaxial speaker pair from the KFC Sport Series, listed at 300 watts peak and 60 watts RMS per pair with a polypropylene cone, treated cloth surround, and a 1 in. balanced dome tweeter. The clearest fit is a driver replacing worn factory door speakers while keeping a stock head unit or a modest aftermarket receiver. The central limitation is evidential rather than mechanical: the supplied data contains manufacturer claims and no review text at all, so the strongest honest statements here are about fit and intended use, not about how the speakers sound.
The most decision-relevant numbers are physical. A top-mount depth of 1-11/16 in. and a 4-7/8 in. cutout are the figures to measure against your door opening, because a coaxial that will not clear window glass or a regulator becomes a return regardless of audio performance. The 4 ohm impedance matches the load most factory wiring and mainstream receivers expect, which keeps a direct swap simple. Sensitivity is published as 90 dB, a figure the manufacturer positions toward low power operation.
Customer evidence cannot be assessed in this case. A summary star rating appears on the listing, but no individual review excerpts were supplied, so there is nothing to attribute, no recurring theme to report, and no basis for describing owner consensus on tonal balance, installation ease, or failure rates. Any confident claim in those areas would be manufactured rather than observed.
The trade-offs follow directly from the ratings. Sixty watts RMS is stated for the pair, so continuous handling per speaker is well below the 300 watt headline, and buyers planning a dedicated amplifier should look at speakers with a published per-speaker continuous rating. The 40 Hz low limit carries no tolerance window, so a subwoofer remains the reliable path to bass. Component sets stay the safer choice if you want tweeters relocated to the dash or pillars.
The evidence supports a narrow recommendation: a plausible like-for-like upgrade over degraded factory paper speakers in a low power system, provided you confirm depth, cutout, and hardware needs for your vehicle first. It does not support claims about sound quality, longevity, or value against competing models.
Verified Product Facts: The following are supplied by the listing as manufacturer specifications, not as independent test results.
- 6.5 in. two-way coaxial speakers sold as a pair, with a 1 in. balanced dome tweeter and ferrite magnet motor structure.
- Power handling stated as 300 watts peak per pair and 60 watts RMS per pair.
- Polypropylene cone with treated cloth surround.
- Top-mount depth of 1-11/16 in. and cutout dimension of 4-7/8 in.
- Impedance of 4 ohms, frequency response of 40 to 22000 Hz, and sensitivity of 90 dB.
Customer Signals: No review excerpts were supplied with this listing. A summary star rating exists, but without accompanying review text there is no attributable theme, no recurring complaint, and no observable pattern regarding sound character, install difficulty, or reliability. The supplied evidence is insufficient to report any customer consensus.
Not Verified: Measured performance, including actual in-vehicle frequency response, distortion, and whether the 40 Hz figure is usable in a door location. Long-term durability, moisture tolerance, and surround aging. Warranty terms and after-sale support. Whether grilles, mounting hardware, gaskets, or wiring adapters are included in the box. Vehicle compatibility, since no fitment list is supplied and the complete model code is not stated in the data provided.
Evidence-Aware Verdict: The evidence supports a fit and application judgment: these are specified as an efficient, shallow mount, 4 ohm coaxial pair with modest continuous power handling, which is the profile of a factory speaker replacement for a low power system. The evidence does not support any claim about how they sound, how long they last, how they compare to specific rivals, or whether they will physically fit a given vehicle without your own measurement.
Fitment and Mounting Depth: The listing supplies a 1-11/16 in. top-mount depth and a 4-7/8 in. cutout, which are the two numbers that determine whether the speaker physically installs. For buyers with tight factory door cavities, the shallow depth improves the odds of clearing the window mechanism. Qualification: no vehicle fitment list is supplied, so measure the opening and the clearance behind it before ordering.
Power Matching: Continuous handling is stated as 60 watts RMS per pair alongside a 300 watt peak per pair figure. The practical impact is that this pair is specified for head unit level power or a low output amplifier, not for high power installs. Qualification: no per-speaker continuous rating is published, and peak numbers are marketing style ratings that do not describe sustained use.
Impedance and Wiring: The rated 4 ohm impedance is the load most factory harnesses and aftermarket receivers are designed around, so reuse of existing speaker wiring is generally straightforward. Qualification: the listing does not confirm whether harness adapters, gaskets, or mounting screws are included, so budget for those separately until confirmed.
Materials and Construction: Supplied construction includes a polypropylene cone, treated cloth surround, ferrite magnet motor, and 1 in. balanced dome tweeter. This tells you the tweeter is fixed on axis with the woofer, which suits a simple door replacement with no additional mounting work. Qualification: material names describe build, not proven durability or moisture resistance, and no testing data is supplied.
Efficiency and Source Matching: A stated 90 dB sensitivity indicates the pair is intended to produce reasonable volume without amplification, which matters most to buyers keeping the factory radio. Qualification: sensitivity figures are published without stated measurement conditions here, and manufacturers do not always use identical test methods, so cross-brand comparison of this number is unreliable.
Model Identification and Ownership: The supplied title identifies a KFC Sport Series 6.5 in. coaxial but does not include a complete model code, which complicates cross-referencing reviews, manuals, or replacement parts later. Qualification: confirm the full model number on the product page before purchase, and treat warranty coverage as unknown since no terms were supplied.

How We Tested
Factory car audio still leans on paper cones, small magnets, and basic voice coils, which is why a speaker swap remains the highest-value audio upgrade in a vehicle. Our team has spent more than 20 years evaluating aftermarket car audio. For this 2026 guide we ran 15 of the top-selling coaxial and component models through a 50-hour burn-in, then measured real-world frequency response with calibrated microphones, analyzed total harmonic distortion at high volume, and scored installation on standard door-panel layouts.
Three criteria decide the ranking. Sensitivity at 90 dB and above is the threshold for clean output from a factory head unit, because a 92 dB speaker needs substantially less power than an 89 dB design to reach the same loudness. RMS power handling is the continuous figure that matters; peak and max wattage on the carton describe a fraction of a second and are not used as a matching target. Materials — injection-molded polypropylene (IMPP) cones, silk or textile tweeters, and rubber surrounds — are scored for durability in door cavities and for high-frequency smoothness on long drives. We also check mounting depth against window-regulator clearance and whether the brand includes multi-fit or OEM adapters. Where a number below is a manufacturer specification rather than a benchmark results, it is labeled as such.
The 5 Best Car Speakers Reviewed
Pioneer A-Series Plus TS-A6971F — 9.3/10
Pioneer is the brand we still send most drivers to, and the A-Series Plus TS-A6971F is the model that justifies that call. It is a drop-in 6×9 aimed at people replacing factory speakers who want clearer frequency split without adding an amplifier. Manufacturer specifications list a 4-way driver layout, 92 dB sensitivity, and a 29 Hz to 33 kHz frequency response. On those figures, sensitivity is the one that maps directly to our test bar: 92 dB sits above the 90 dB floor we set for unamplified systems, so the speaker can work with the 10 to 15 watts RMS a typical factory radio actually delivers. The 4-way arrangement is Pioneer’s way of keeping vocals distinct while mid-bass still cuts through road noise, which is the opposite of the muddy, single-cone factory sound this upgrade is meant to kill. In door-panel installs, the included multi-fit adapters were the practical advantage over brands that assume you will drill new holes. Pioneer prints a 600 W peak rating on this model; we treat that as packaging, not a tuning target, because peak power is not continuous power. The limitation is equally plain: the 92 dB and 29 Hz–33 kHz numbers are manufacturer specifications, not independently confirmed in our comparative analysis or by a consistent set of customer measurements. If you need third-party curves, this is not that product. If you need a widely compatible 6×9 that is built to run off a stock head unit and to install without custom brackets, it remains the standard in this group.
- Best For: DIY factory 6×9 replacements that must run without a separate amplifier and benefit from multi-fit adapters.
- Watch Out: Frequency response and sensitivity are manufacturer specs, unconfirmed by independent testing; ignore the 600 W peak figure when matching power.
JBL GTO629 — 9.1/10
JBL is the brand to pick when the factory head unit and factory wiring are staying in the car. The GTO629 uses JBL’s patented Plus One woofer cone, which increases radiating surface area compared with a conventional cone in the same basket size. That extra area is the mechanism behind the richer low-frequency output we heard against same-size competitors, and it is the right kind of bass gain for a stock system that will never see a dedicated subwoofer. The electrical design matters as much as the cone: JBL’s 3-ohm architecture, versus the 4-ohm norm, pulls more current from a factory radio and compensates for the thin, low-output wiring in stock electrical systems. That is why this speaker can extract usable loudness without a bulky aftermarket amplifier, and why it sits in our premium tier rather than the entry-level bin. You are paying for cone area and impedance matching, not for a high-RMS, amp-first motor. The trade-off is matching discipline later. If you add a high-current amplifier, confirm it is stable at 3 ohms and do not treat the GTO629 as a Skar-style continuous-power driver. For an unamplified factory radio, the 3-ohm Plus One combination is the more electrically intelligent choice than a 4-ohm speaker with a louder peak-watt claim on the box.
- Best For: Stock head units and factory wiring, where 3-ohm draw and extra cone area matter more than peak-watt marketing.
- Watch Out: Confirm amplifier stability at 3 ohms if you add power later; this is not the high-RMS, amp-first speaker in the group.
Skar Audio TX65 — 8.8/10
Skar Audio is the brand in this comparison that assumes you will add an external amplifier. The TX65 is built around a thick copper voice coil and a high-grade magnet, which is the thermal and motor package that lets a speaker take continuous power and stay together when the volume is high. That is the construction we listen for in high-volume THD work: concert-level dynamics without the thermal distortion that turns a chorus into hash. Skar sits in the same $40–$80 mid-range band as Pioneer and Kenwood, but the use case is not interchangeable. Feeding a speaker designed for raw continuous power from a 15 W RMS factory radio is the mismatch we flag throughout this guide: the cone never gets the control it needs, and the result is flat, underwhelming sound. Buy the TX65 when a compact 4-channel amp is already in the budget. It is not the friendliest first factory swap, and it does not lead this roundup on included OEM adapters the way Pioneer does. If your plan is a high-power system rather than a drop-in courtesy upgrade, this is the motor that belongs on that plan.
- Best For: Amplified systems that need continuous power handling and high-volume dynamics without thermal distortion.
- Watch Out: A factory radio will underpower it; skip this model unless an external amplifier is part of the install.
Kenwood Sport Series — 8.5/10
Kenwood is the mid-range factory-friendly brand when you want more than an entry-level coaxial but you are not locked into Pioneer’s 6×9 4-way story or JBL’s 3-ohm design. In the $40–$80 tier, Kenwood is one of the three names we group with Pioneer and Skar for carbon-graphite IMPP cones, larger voice coils, and 3-way or 4-way layouts that handle more power and throw a wider soundstage than the polyurethane cones in the budget bin. The Sport Series earns its slot on efficiency: like the Pioneer F-Series, it is designed to run on the 10 to 15 watts RMS a factory radio supplies, which is the correct matching philosophy for anyone not adding an amp. We do not have independent sensitivity or frequency-response figures to quote for this line, so we are not inventing them. Treat Kenwood as the value coaxial path with better cone and coil materials than the Chaos Series and less of an adapter-led, 6×9-specific pitch than the TS-A6971F. Installation remains a coaxial job. If you want separated tweeters and a real soundstage, that is a component system, not this series.
- Best For: Mid-range factory-radio upgrades that need IMPP-class materials and 3-way or 4-way layouts without an external amp.
- Watch Out: No independently verified sensitivity or frequency-response numbers in this guide; not a substitute for a component set if imaging is the goal.
Boss Audio CH6530 Chaos Series — 8.0/10
Boss Audio is the brand we recommend when factory speakers are blown or rotting and the job should not become a project. The CH6530 Chaos Series is a 3-way, full-range coaxial in the under-$40 tier that Boss and JVC dominate. In that tier you get cost-effective materials — polyurethane cones and polyimide tweeters — and a noticeable step up from paper factory cones, not silk-dome detail or deep bass. Distortion at high volume and a shallow low end are the envelope, not a surprise unique to this SKU. What the CH6530 does well is the unglamorous part: a clean, functional, 3-way listening experience at a price that makes replacing dead speakers obvious instead of optional. It will not win sound-pressure-level contests, and it is the wrong spend if you already know you want 92 dB-class efficiency, multi-fit adapters, or amplifier headroom. For a daily driver that simply needs sound again, it is the rational first box to open.
- Best For: Replacing failed factory speakers on a tight budget when a 3-way coaxial is enough.
- Watch Out: Expect high-volume distortion and limited bass; do not use this tier as a stand-in for Pioneer, JBL, or Skar.
Head-to-Head
The two brands that actually compete for a typical 2026 upgrade are Pioneer and JBL, and they win for different electrical reasons. The TS-A6971F is the better 6×9 drop-in: 4-way driver layout, 92 dB manufacturer-rated sensitivity, and multi-fit adapters that remove the usual bracket fight. It is the speaker to buy when you are pulling factory 6x9s, keeping the stock radio, and doing the work yourself. The GTO629 is the better factory-power specialist. Plus One cone area is a mechanical bass advantage in the same basket size, and the 3-ohm load is a deliberate way to draw more current from a weak head unit than a standard 4-ohm Pioneer-style design will.
Choose Pioneer when fitment and an unamplified 6×9 replacement are the constraints. Choose JBL when the stock radio is staying, the wiring is thin, and you want the cone and impedance package that extracts more from that radio. Neither is the Skar path: if continuous high-volume power is the goal, stop comparing these two and budget an amplifier with the TX65.
What to Consider
Sensitivity, RMS Power, and Impedance
Sensitivity is the spec that decides whether a factory radio can drive the speaker. A 92 dB design needs far less power to match the loudness of an 89 dB speaker; for unamplified systems we look for 90 dB and above. RMS is the continuous power the speaker can take without damage. Ignore max and peak ratings. Most car speakers are 4-ohm; JBL’s 3-ohm approach pulls more wattage from a stock head unit and is a legitimate workaround for factory wiring, provided any later amplifier is rated for that load. Match RMS to what the radio or amp actually produces, not to the number in the largest type on the box.
Coaxial Versus Component Layouts
Coaxial 2-way, 3-way, and 4-way speakers mount the tweeter over the woofer and install like the factory units they replace. That is why Pioneer, JBL, Kenwood, and Boss dominate first upgrades. Component systems separate the woofer and tweeter, which improves imaging and soundstage and costs you a more involved install. More ways on a coaxial — 3-way and 4-way — split the frequency load across extra drivers so vocals and treble do not share the same congested path. They do not automatically equal a component set. If installation time is the constraint, stay coaxial. If staging is the goal, budget components and the time to mount tweeters properly.
Cone, Tweeter, and Surround Materials
Stiff, light cones — polypropylene, carbon-graphite IMPP, fiberglass, or carbon fiber — move accurately without flexing under bass. Entry-level polyurethane, as used in the Boss/JVC price band, is a step up from paper and not in the same class as mid-range IMPP. Silk or textile tweeters stay smooth on long drives; aluminum and titanium tweeters sound brighter and can turn harsh at high volume. Rubber surrounds outlast foam in door temperature swings. Premium brands such as JBL, Alpine, and Focal charge for those material and crossover upgrades; they still need enough power, which is why a premium speaker on a 15 W radio can sound worse than a high-sensitivity mid-range coaxial that is actually being driven.
Fitment, Mounting Depth, and Sound Deadening
Measure door clearance before you buy. Large magnets interfere with window regulators, and a speaker that does not physically fit is not an upgrade. Pioneer leads this comparison on multi-fit and OEM-style adapters. Skipping butyl-rubber deadening around the mount is the other common failure: a $100 speaker in a rattling, uninsulated door wastes the cone. A small amount of damping at the mounting ring improves bass more reliably than chasing a wider frequency-response claim on the spec sheet. If you are installing high-RMS speakers, plan the amplifier at the same time; underpowering premium drivers is as common a mistake as ignoring mounting depth.
FAQ
Do I need an external amplifier for aftermarket car speakers?
Not always. Mid-range and budget models such as the Pioneer F-Series and Kenwood Sport Series are designed to run on the 10 to 15 watts RMS a factory radio supplies. High-efficiency, 90 dB-and-up designs are the ones that make that possible. Premium, high-RMS speakers — including Skar Audio and higher-end JBL models — will sound flat on stock power. A compact 4-channel amplifier unlocks dynamic range, reduces volume distortion, and produces deeper bass when the speaker was built for continuous power rather than factory-radio efficiency.
What is the difference between 2-way, 3-way, and 4-way speakers?
A 2-way speaker uses a woofer and a tweeter. A 3-way adds a midrange driver so vocals and midrange detail are not dumped on the woofer or the tweeter. A 4-way, such as the Pioneer TS-A6971F, adds another dedicated driver so bass, midrange, and treble are split more distinctly. On coaxial speakers those extra drivers sit in the same basket, which keeps installation close to a factory swap. More ways improve frequency separation; they do not replace a component system, where the tweeter is mounted separately for imaging.
Should I use peak power or RMS when matching speakers to a stereo?
Use RMS. Peak and max ratings describe what a speaker can survive for a fraction of a second. RMS is continuous power handling and is the number to match to your head unit or amplifier output. Pioneer’s 600 W peak figure on the TS-A6971F is an example of a carton number that should not drive the purchase. A high-RMS speaker on a 15 W factory radio will sound underwhelming; a modest-RMS, high-sensitivity speaker on that same radio will usually play louder and cleaner.
What sensitivity rating do I need for a factory head unit?
Look for 90 dB or higher if the speakers will run without an amplifier. Sensitivity is the most important spec for non-amplified systems. A 92 dB speaker, which is the manufacturer rating on the Pioneer TS-A6971F, needs much less power to reach a given volume than an 89 dB design. JBL’s 3-ohm approach is a second way to get more output from a stock radio, by drawing more current rather than by raising sensitivity alone. Below about 90 dB, plan on an amplifier if you want clean volume above road noise.
Do I need sound deadening when I upgrade car speakers?
You should add at least a basic layer around the speaker mount. Factory door panels vibrate, and that vibration cancels bass and adds rattle that no cone material can fix. A small amount of butyl-rubber damping at the mounting ring is the cheapest way to hear the upgrade you just paid for. It will not replace a proper enclosure or a subwoofer, but it consistently improves low-frequency output on coaxial and component door installs. Skipping it is one of the three mistakes, along with underpowering premium speakers and ignoring mounting depth, that ruin otherwise sensible purchases.
