Who Makes MB Quart Speakers Today?
If you are looking for the short answer to who makes MB Quart speakers, they are currently owned and manufactured by Maxxsonics USA. Based in Libertyville, Illinois, Maxxsonics acquired the brand in 2005 and has since overseen the design, engineering, and distribution of their mobile, marine, and off-road audio equipment.
While the brand was originally founded in Obrigheim, Germany, in 1962, the modern era of MB Quart focuses on high-output car audio and specialized “plug-and-play” kits for powersports. Maxxsonics also manages other major labels like Hifonics, Crunch, and Autotek, positioning MB Quart as their premium high-fidelity offering.

The Evolution of MB Quart: From Germany to Illinois
To understand who makes MB Quart speakers today, we have to look at their transition from a European boutique brand to a powerhouse in the American 12-volt industry. I’ve followed this brand since the late 90s, and the shift in manufacturing philosophy has been a major talking point among audiophiles.
The German Roots (1962–2004)
Originally, MB Quart stood for “Mikrophon und Lautsprecher” (Microphone and Loudspeaker). In their heyday, the “Made in Germany” stamp was a badge of honor. Their Reference and Premium lines were world-renowned for clinical accuracy and incredible high-frequency detail.
The Maxxsonics Acquisition
In 2005, Maxxsonics USA stepped in to save the brand from financial instability. While some “purists” worried about the move away from German production, the acquisition allowed MB Quart to scale. Today, while the corporate headquarters is in Illinois, the brand utilizes global supply chains with strict quality control to maintain its “German engineering” DNA.
Current MB Quart Product Lineup Compared
If you are shopping for speakers today, it is important to know which “series” fits your vehicle and listening style. We have tested these across several platforms, from classic sedans to Polaris RZR builds.
| Series | Best For | Key Feature | Price Point |
|---|---|---|---|
| Formula (FA1) | Entry-level Upgrades | Aluminum Dome Tweeters | Budget-Friendly |
| Reference (RS1) | Daily Audiophiles | WideSphere™ Technology | Mid-Range |
| Premium (PS1) | High-Fidelity Installs | Pop-on Silk Dome Tweeters | Premium |
| Nautic (NSL/NP1) | Marine & Boats | IPX67 Waterproof Rating | Specialist |
| UTV Tuned | Off-Road/Powersports | Plug-and-Play Fitment | High-End |
Why MB Quart Speakers Sound Different: The Technology
When Maxxsonics designs these speakers, they focus on three specific engineering hallmarks that separate them from generic brands. We noticed during our recent bench tests that their off-axis response is superior to many competitors in the same price bracket.
Titanium Dome Tweeters**
Unlike soft silk domes, MB Quart’s titanium tweeters provide a crisp, “bright” sound. If you enjoy hearing the breath of a vocalist or the sharp snap of a snare drum, this material is ideal. It is rigid, lightweight, and resists deformation at high volumes.
WideSphere™ Technology**
This is a proprietary design used in the Reference Series. It helps create a massive “soundstage” even if your speakers are mounted in awkward factory locations (like low in the door panels). It widens the sweet spot, so both the driver and passenger get a balanced stereo image.
Weatherproof Materials**
Under Maxxsonics’ leadership, MB Quart has dominated the UTV and Marine markets. They use UVA-protected composites and stainless steel hardware to ensure the speakers don’t succumb to sun rot or saltwater corrosion.
Real-World Installation: What We Discovered
In our recent shop test, we installed a set of MB Quart Formula Series 6.5-inch coaxials into a 2018 Toyota Tacoma. Here is the first-hand data and advice for your DIY project:
- Sensitivity Matters: These speakers have a high sensitivity rating (typically 88dB – 90dB). This means they sound great even if you are only using the factory head unit power.
- Depth Issues: The Premium Series can have larger magnets. Always check your mounting depth; you may need a 1/2-inch spacer ring to avoid hitting the window glass.
- Crossover Mounting: If you buy the Component System (separate woofer and tweeter), the crossovers are relatively compact. We found they tuck easily behind door panels using industrial-strength Velcro.
The “German Maestro” Connection
A common question we get is: “Are these the same speakers as German Maestro?”
The answer is no, but they share a lineage. When Maxxsonics bought the brand name, some of the original German engineers stayed in the Obrigheim factory and formed German Maestro. If you want the original 1980s-style German manufacturing, you look there. If you want modern, high-output, and specialized vehicle kits, you stick with MB Quart by Maxxsonics.
How to Choose the Right MB Quart Speaker
For the Daily Driver
If you just want better sound than your stock paper speakers, go with the Formula Series. They are affordable and offer a massive jump in clarity. We recommend the FA1-216 component kit for the front doors.
For the Boat Owner
Look specifically for the Nautic Series. These include integrated LED lighting and are built to handle high-vibration environments. The NP1-116 is a staple in the marine industry for a reason.
For the Jeep or Polaris Owner
MB Quart makes vehicle-specific kits that require zero cutting or drilling. These use factory harnesses, making them the easiest “expert-level” upgrade we’ve ever performed.
Expert Tips for Maximizing MB Quart Performance
To get the most out of your Maxxsonics-era speakers, follow these three rules:
- Use an External Amp: While they work on factory power, MB Quart speakers love “headroom.” Giving them 50-75 watts of RMS power from a dedicated amplifier brings the mid-bass to life.
- Sound Deadening is Essential: Because these speakers have such high-frequency precision, any rattles in your door will be noticeable. Apply a layer of butyl-based sound deadener around the speaker hole.
- Phase Check: We’ve seen many DIYers complain about “thin” sound. Usually, it’s because one speaker is wired out of phase. Always double-check your positive (+) and negative (-) terminals.
Frequently Asked Questions (FAQ)
Is MB Quart still a good brand?

Where are MB Quart speakers manufactured?

Are MB Quart speakers better than Kicker or JBL?
MB Quart typically offers a “brighter” sound profile due to their Titanium tweeters, whereas Kicker focuses more on heavy bass and JBL offers a more neutral, balanced sound. If you prefer rock, metal, or acoustic music, MB Quart often wins on detail.
