The MB Quart QL 60 C is a hidden gem from the golden era of German high-fidelity engineering. Manufactured around 1995, these floorstanding speakers are celebrated by audiophiles for their "extra quality" construction and the signature neutral, detailed sound typical of classic German brands like Canton and Heco.

• You own a high-power amplifier (50W+ RMS).
• You have a treated, deadened vehicle.
• You crave treble extension and midrange purity over bloated bass.
• You appreciate legendary German build quality.

• Clear midrange and detailed highs
• Compact, shallow design for tight spaces
• Good value for an OEM-upgrade level speaker

• Air-core inductors (no core saturation at high power).
• Mylar capacitors (low distortion vs. cheap ceramics).
• Three tweeter level adjustments: 0dB, -3dB, and -6dB. This allows you to tame the titanium highs in reflective interiors like glass-filled cars.

• Poor condition (needs re-foam, scratches): $50 - $80
• Good condition (working, minor wear): $100 - $150
• Mint in box (NOS): $200 - $300

Users frequently describe the QL 60 C as offering a "tonally balanced" and "neutral" sound that avoids artificial coloration. High-Frequency Precision: The signature MB Quart titanium dome tweeters

The Crossover Network

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.
