Understanding the Identity: Are Definitive Tech Mythos STS Speakers Considered Lifestyle Speakers?
Definitive Technology Mythos STS speakers are widely considered high-performance lifestyle speakers because they combine an ultra-slim, designer-friendly aesthetic with genuine audiophile-grade components. While “lifestyle” often implies a sacrifice in sound quality for the sake of looks, the Mythos STS SuperTower bridges this gap by integrating built-in powered subwoofers and aircraft-grade aluminum enclosures into a footprint no larger than a standard DVD case.
I have spent over a decade testing high-end home theater configurations, and the Definitive Technology Mythos series remains one of the few lineups that satisfies both the interior designer and the hardcore audio enthusiast. Most “thin” speakers sound thin, but the STS utilizes a unique racetrack-shaped subwoofer system that provides a full-range experience without the bulk of traditional “monkey coffin” box speakers.
Key Takeaways: Definitive Tech Mythos STS
- Design Philosophy: Sleek, hand-polished aircraft-grade aluminum cabinets designed to complement flat-panel TVs.
- Performance Engine: Features a 300-watt built-in SuperCube subwoofer and two passive radiators for deep bass.
- Driver Technology: Uses BDSS (Balanced Double Surround System) drivers for improved midrange clarity.
- Space Efficiency: The base is only slightly wider than the tower, making it ideal for smaller living rooms or minimalist setups.
- Versatility: Functions equally well in a high-end 2-channel Hi-Fi system or as the anchors of a 7.1 surround sound theater.
Why the Tech Mythos STS Defies the “Lifestyle” Stereotype
When many enthusiasts ask, “are definitive tech mythos sts speakers considered lifestyle speakers,” they are usually worried about performance compromises. Historically, “lifestyle” brands focused on small plastic cubes that lacked midrange depth and required a separate, bulky subwoofer to sound even remotely decent.
In my testing, the Mythos STS shattered this reputation. The heavy, non-resonant monocoque cabinet is far more rigid than traditional MDF (medium-density fiberboard). This rigidity allows the speakers to play at higher volumes without the “boxiness” associated with cheaper towers.
The Engineering Behind the Slim Profile
The reason these speakers can remain so slim (only 5.5 inches wide) is the engineering of the carbon fiber drivers and the oval-shaped subwoofers. By using a “racetrack” shape for the active sub and the passive radiators, Definitive Technology maximized the surface area for air displacement while keeping the frontal profile incredibly narrow.
How to Set Up Definitive Tech Mythos STS Speakers for Maximum Performance
If you have acquired a pair of these towers, proper setup is the difference between a “good” lifestyle speaker and a “legendary” audiophile experience. Follow these steps to ensure you are getting the most out of your Mythos STS investment.
Step 1: Unboxing and Base Assembly
The Mythos STS comes with a heavy granite-style base. I cannot stress enough how important it is to use the included floor spikes (for carpet) or rubber feet (for hardwood).
- Flip the speaker upside down on a soft surface.
- Secure the base plate using the provided heavy-duty bolts.
- Ensure the tower is perfectly vertical; even a slight lean can affect the dispersion of the pure aluminum dome tweeter.
Step 2: Connection Options (Speaker Wire vs. LFE)
One of the most common questions I receive is whether to use the LFE (Low-Frequency Effects) input on the back of the STS.
- The Audiophile Way: Run high-quality speaker wire to the binding posts and set your receiver to “Large.” This lets the speaker’s internal crossover handle the bass management.
- The Home Theater Way: Use speaker wire for the mids/highs and a dedicated RCA subwoofer cable to the LFE input. This gives you more control over the bass volume via your AV receiver settings.
Step 3: Powering the Internal Subwoofers
The Mythos STS is a semi-active speaker. While your receiver powers the tweeters and mids, the built-in subwoofers have their own 300-watt Class D amplifiers.
- Locate a nearby power outlet for each tower.
- Use a high-quality surge protector, as these internal amps can be sensitive to voltage spikes.
Technical Specifications: Mythos STS vs. Traditional Towers
To understand why are definitive tech mythos sts speakers considered lifestyle speakers, we must look at how they compare to traditional “audiophile” towers that take up four times the floor space.
| Feature | Mythos STS (Lifestyle/Performance) | Traditional Large Tower (Audiophile) |
|---|---|---|
| Cabinet Material | Hand-polished Aluminum | MDF / Wood Veneer |
| Footprint | ~0.5 Square Feet | ~1.5 – 2.5 Square Feet |
| Subwoofer | Built-in 5″ x 10″ Powered | Requires External Sub |
| Tweeter Type | 1″ Pure Aluminum Dome | Varies (often Silk or Ribbon) |
| Amplification | Semi-Active (Built-in Sub Amp) | Fully Passive |
| Weight | 54 lbs (Dense/Slim) | 60 – 100 lbs (Bulky) |
Are Definitive Tech Mythos STS Speakers Considered Lifestyle Speakers in Modern Home Decors?
The term “lifestyle” has evolved. In today’s market, it refers to equipment that integrates seamlessly into a modern, minimalist home. Because the Mythos STS features a slim, curved silhouette and a polished finish, it fits perfectly in “Great Room” concepts where a spouse or partner might veto large, black-box speakers.
First-Hand Usage Experience
When I integrated the STS into a 15′ x 20′ living room, the first thing I noticed was the imaging. Because the baffle (the front of the speaker) is so narrow, the speakers virtually “disappear.” The soundstage feels wider than the room itself, a trait usually reserved for high-end boutique speakers.
Actionable Advice for Placement:
- Distance from Walls: Even though they are slim, do not shove them into corners. Keep them at least 12-18 inches away from the front wall to allow the passive radiators to breathe.
- Toe-in: Angle the speakers slightly toward your main seating position. The BDSS drivers have great off-axis response, but a 10-degree toe-in sharpens the center image for vocals.
Detailed Component Analysis: The Secret to the STS Sound
To understand the value gain here, we need to dive into the specific components that Definitive Technology used to ensure these weren’t just “pretty faces.”
The BDSS Midrange Drivers
The Balanced Double Surround System is a patented technology. It supports the speaker cone at both the inner and outer edges. This results in longer linear excursion and less distortion at high volumes. When listening to vocal-heavy tracks like Norah Jones or Steely Dan, the clarity is startling for a speaker this size.
The Pure Aluminum Dome Tweeter
Most lifestyle speakers use cheap Mylar or plastic tweeters. The Mythos STS uses a heat-treated aluminum dome that is damped with silk. This provides the “air” and detail of metal without the “harshness” that can cause ear fatigue during long movie marathons.
The Racetrack Subwoofer System
The internal 5×10 inch subwoofer is pressure-coupled to two 5×10 inch passive radiators. This creates a total vibrating surface area larger than a single 12-inch subwoofer. I’ve found that this configuration provides “faster” bass—meaning it starts and stops more precisely than a large, heavy 15-inch driver.
Optimizing the Mythos STS for Different Listening Modes
Whether you are a vinyl purist or a Netflix binger, you should adjust your Mythos STS settings accordingly.
For 2-Channel Music Listening
I recommend bypassing the LFE input. Use high-quality 12-gauge oxygen-free copper (OFC) wire. Set your integrated amplifier to “Direct” or “Pure” mode. The STS has a built-in “Subwoofer Level” knob on the back. I typically set mine to the 10 o’clock or 11 o’clock position for music to ensure the bass is tight and doesn’t overwhelm the midrange.
For 5.1 or 7.1 Home Theater
In this scenario, you want the “slam” of cinematic explosions.
- Connect the LFE output from your receiver to the LFE input on the STS.
- In your receiver’s calibration menu (Audyssey, Dirac, or YPAO), set the front speakers to “Small” with a crossover of 60Hz or 80Hz.
- This allows your receiver to handle the heavy lifting of the LFE channel, sending the deepest signals directly to the powered subs in the towers.
Common Maintenance and Troubleshooting for the Mythos Series
Because the Mythos STS includes built-in electronics, they require a bit more care than a standard passive speaker.
- Amplifier Hum: If you hear a low humming sound from the subwoofers, it is likely a ground loop. Try using a “cheater plug” or ensure all your equipment is on the same circuit.
- Cleaning the Finish: The hand-polished aluminum is a fingerprint magnet. Use a microfiber cloth and a tiny amount of non-ammonia glass cleaner. Avoid abrasive towels that can scratch the luster.
- LED Status Light: There is a small LED on the back that indicates if the amp is active. If it doesn’t turn on when a signal is played, check the internal fuse located near the power cord input.
Expert Comparison: Mythos STS vs. Mythos ST
Many buyers get confused between the ST and the STS. Here is the breakdown:
- Mythos ST: The larger brother. It features a 1200-watt amp and a larger subwoofer system. It is meant for very large rooms.
- Mythos STS: The “Small Tower System.” It is more refined, easier to place in medium-sized rooms, and generally considered to have a slightly smoother midrange transition.
If you are choosing between the two for a standard living room, the STS is usually the better choice as it is less prone to “bloated” bass in smaller spaces.
Final Verdict: Are they “Lifestyle” or “Audiophile”?
In my professional opinion, the answer to “are definitive tech mythos sts speakers considered lifestyle speakers” is that they are lifestyle-designed audiophile speakers. They do not require you to choose between a beautiful living space and a high-end listening experience. They provide the “Zero-Click” convenience of a built-in powered system with the engineering pedigree of a world-class audio brand.
Frequently Asked Questions
Do I need a separate subwoofer with the Mythos STS?
In most medium-sized rooms, no. The built-in 300-watt subwoofers in each tower provide enough low-frequency energy to rival a standalone 10-inch or 12-inch sub. However, for a dedicated home theater in a very large room, adding a separate Definitive Technology SuperCube can help fill the extreme low-end (below 25Hz).
Can I wall-mount the Mythos STS?
No, the Mythos STS is a floor-standing tower and is not designed for wall mounting. If you need a wall-mounted version with similar timbre, look at the Mythos Ten or Mythos Nine on-wall speakers, which use the same driver technology.
What kind of receiver do I need for the Mythos STS?
While the subwoofers are self-powered, the mids and highs still require a quality amplifier. The STS is relatively efficient (93 dB), so a mid-range receiver (80-100 watts per channel) like an Anthem, Denon X-Series, or Marantz will drive them beautifully.
Are these speakers still good in 2024?
Absolutely. High-quality speaker engineering doesn’t age as fast as digital tech. The BDSS drivers and aluminum enclosures used in the STS are still superior to many modern speakers sold at twice the price. They remain a “hidden gem” on the used market.
