Active subwoofer, bass reflex, downfire
The Quantum 731A is the perfect low-bass counterpart to the Quantum 750 series. Besides the extremely low-resonance 45 mm case front on a corpus with multiple stiffening, it offers a clear and modern language of shape that is available in perfect high-gloss or silk-matt varnish finishes. The latest-generation computer-optimised long-throw subwoofer chassis delivers uncompromisingly clean and dynamic basses.
The Quantum 731A is available in a black, white or black-mocha finish. A long-throw subwoofer chassis with a diameter of 300 mm and hardened paper cone, high-strength die-cast basket and ventilated high-performance voice coil 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 power amplifier guarantees highest level reserves.
