C Extra Quality: Mb Quart Ql 60

The MB Quart QL 60 C is a high-performance floor-standing speaker system originally released around 1995. Known for its precision German engineering, it was designed as a "four-way" bass-reflex system with a front-facing port, making it relatively flexible for room placement.  Technical Specifications  Design Type: 4-Way Floor-standing, Bass Reflex. Dimensions: 260 x 1020 x 290 mm ( ). Weight: Approximately 19.5 kg (43 lbs) per unit.

Retail Price (1995): Approximately 1149 DM (Deutsche Marks).

Tweeter Material: Pure titanium, which is a signature of MB Quart's "original recipe" German-made drivers.  Sound Profile & Quality 

Reviews from enthusiasts highlight several key performance traits: 

Clarity & Detail: The speakers are noted for being "clear, open, and robust". Users often describe the high frequencies as exceptionally crisp and detailed due to the titanium tweeters.

German Sound Signature: Often described as having a "German" sound—meaning neutral, balanced, and precise without artificial coloring.

Bass Performance: While they provide a "deep" and "very pleasant" bass that doesn't overload the ear, some users find them slightly bass-light depending on the room, though they remain highly capable for most musical genres.

Amplifier Sensitivity: They generally have a high sensitivity, meaning they don't require massive power to drive, but they benefit significantly from high-quality amplification (e.g., tube amps) to unlock their full musicality.  Collector's Value 

These speakers are relatively rare on the secondhand market today. They are considered "German Gems" by audiophiles who appreciate their build quality, which often surpasses modern speakers at similar price points.

MB Quart QL 60 C Extra Quality — Product Overview

The MB Quart QL 60 C Extra Quality is a compact 2-way coaxial car speaker designed for clear midrange and extended high-frequency response in aftermarket car audio systems. It’s aimed at listeners who want improved clarity and detail over factory speakers while fitting into common small-mount locations (e.g., 4"–6.5" openings depending on adapter).

1. The "Brightness" Factor – Taming the Titanium Dome

The #1 user complaint about the QL 60 C is the aggressive, piercing treble. This is by design (German "high-fidelity" monitoring sound), but it can be fatiguing.

Solutions:

• Tweeter Positioning (Critical): Do not aim the tweeters directly at your ears (e.g., on sail panels aimed at your head). Instead:
  • Mount them high (A-pillar or dash corners) and aim them across the windshield to reflect off the glass.
  • Or mount them low in the door kick panels, firing across the vehicle.
• EQ Settings: Cut frequencies between 2.5 kHz – 5 kHz by 2–4 dB. Leave the very top end (10 kHz+) flat or slightly boosted for air.
• Attenuation: Use the included -3 dB tweeter attenuation jumper. If yours is missing, add a 2.2 Ohm – 3.3 Ohm resistor in series with the positive tweeter wire.

Pros & Cons

Sound Signature: The Voice of the QL 60 C

To call the MB Quart QL 60 C "neutral" would be a lie. It is transparently forward. Here is what you actually hear:

Part 2: Unboxing and First Impressions – The Heft of Authority

If you manage to find a new old stock (NOS) set of the MB Quart QL 60 C, the first thing you will notice is the weight. Modern "budget high-end" speakers often feel hollow. The QL 60 C does not.

The Woofer (6.5" / 165mm):

• Chassis: A stamped steel basket, but unusually thick. MB Quart applied a special anti-resonance coating (often a black textured paint) to reduce ringing.
• Cone: The QL series utilized a polypropylene cone with a mineral-filled coating. The "Extra Quality" version often features a slight reinforcement weave.
• Surround: High-roll foam surround. Note for buyers: Foam rots over time. Vintage QL 60 C units need inspection, but fresh units offer superior damping and response speed compared to rubber.
• Motor structure: A substantial ferrite magnet with a vented pole piece to cool the voice coil.

The Tweeter (1" / 25mm):

• Type: Titanium dome. This is the classic MB Quart signature. Unlike silk or textile domes, titanium provides explosive attack and shimmering highs.
• Housing: The tweeter comes in a flush-mount cup and a surface-mount pod with a swivel mechanism for aiming.

The Crossover Network: This is where the "Extra Quality" shines. The crossover is not a tiny plastic brick. It is a sturdy board featuring air-core inductors and Mylar capacitors. The slopes are typically 12dB/octave (Linkwitz-Riley alignment) to ensure a smooth transition between the woofer and tweeter.
