The MB Quart QL 60 C Extra Quality is more than a speaker; it is a philosophy. In an era where DSPs can make any cheap speaker sound flat, the MB Quart demands that you rise to its level. It is uncompromising, occasionally unforgiving, but always exhilarating.
If you find a clean set, treat them with respect. Give them clean power, proper installation, and high-quality source material. In return, they will deliver a soundstage so wide and detailed that you will close your windows, turn off the navigation voice, and simply listen.
The "Extra Quality" was never just about the polypropylene cone or the titanium dome. It was about the extra quality of experience. And that, dear audiophile, never goes out of style.

Analytical Clarity: These speakers are known for an uncolored, honest sound. Reviewers often note their "German" sound signature—extremely detailed and crisp in the high frequencies, often attributed to the high-quality titanium dome tweeters.
Precision Bass: Unlike consumer-grade speakers that boost "muddy" low-end, the QL 60 C features a front-ported design that provides tight, fast, and musical bass that does not overwhelm the midrange.
Soundstage: When paired with a quality amplifier (such as vintage Yamaha or Denon units), they are praised for creating a deep, three-dimensional soundstage where the positioning of instruments is clearly defined. Build and Legacy
The QL 60 C cabinets are often finished in high-quality veneers, such as black ash or cherry, with a solid build that survives well on the second-hand market.
The Buyout Factor: Many enthusiasts seek out the QL series because they were manufactured in Germany before MB Quart was acquired by Maxxsonics in 2005. Post-2005 models often saw a shift in manufacturing locations and materials.
Current Value: On the used market, these speakers are considered a "hidden gem" or a "steal," often outperforming modern speakers that cost significantly more.

The MB Quart QL 60 C “Extra Quality” variant represents the pinnacle of the legendary QL series, engineered for audiophiles seeking reference-grade sound in a vehicle. With premium materials and tighter tolerances, this version delivers superior dynamics, clarity, and low-end authority over standard models.
The passive crossovers included with the QL 60 C are substantial. They aren't cheap circuit boards hot-glued into a plastic box. They are heavy, potted units designed to handle serious power. They typically offer selectable tweeter attenuation (usually 0dB, -2dB, -4dB), which is essential for tuning those titanium domes to your specific listening environment.
Before diving into technical specs, it is crucial to understand MB Quart's naming hierarchy. The "QL" series traditionally sat in the mid-to-upper tier of their catalog. The "C" denotes a component system (separate woofer and tweeter with an external crossover). The phrase "Extra Quality" is not just marketing fluff; historically, it indicated upgraded materials compared to the standard "QL" line.
Key indicators of the "Extra Quality" badge include:
For the buyer, this translated to a speaker capable of handling slightly more RMS power (typically 60-80 watts RMS) while delivering lower distortion at high volumes than its standard siblings.
