Quantum 6725 A

Quantum 6725 A



Active subwoofer, bass reflex, downfire

The Quantum 6725A is the perfect low-bass counterpart to the Quantum 670 series. Besides the extremely stable design of the corpus with multiple stiffening, it comes in the elegant look of the Quantum 670 series with handsomely curved side panels. The computer-optimised long-throw subwoofer chassis with downfire array produces uncompromisingly clean and dynamic basses.

The Quantum 6725A is available with a black and mocha-coloured corpus, the front panel on both versions possesses a black piano-lacquer finish. A long-throw subwoofer chassis with a diameter of 250 mm with its linearised double-magnet system is responsible for ideal bass precision. The high-gloss base plate maintains a defined distance to the chassis for optimum level efficiency, the high-performance and full-featured power amplifier guarantees highest level reserves.
