With the QS loudspeaker series the traditional brand MB Quart offers a successful mix of a very good price/performance ratio and optimal installability. The linearly tuned speakers also impress with their natural sound performance. By using a 3 ohm voice coil, the MB Quart QS speakers have a very high efficiency. This means that even with low power (as they often come directly from the car radio), a very good sound performance and volume is achieved.

Due to the rear ventilation of the voice coil, a constant cooling of the magnet driver is guaranteed, so that nothing stands in the way of lasting music enjoyment. The developing of the QS Component systems was focused on good sound quality, but also on easy installation. The very compact 12dB cable crossover fits in every little gap.
