Bowers & Wilkins ASW825B 12 inch Active Subwoofer 1000 WATT

There are four subwoofers in the 800 Series and, although the ASW825 is the smallest of the four, it is still a substantial performer.

The 300mm (12 in) driver features our ultra-rigid Rohacell® sandwich cone that can move prodigious amounts of air with almost perfect piston-like control. It has a 100mm (4 in) diameter voice coil and massive magnet assembly for high power handling without compression, which enables the subwoofer to produce true low-frequency sounds, from the subtle recreation of the acoustic of a large space to the most demanding film special effect.

Powering this driver with consummate ease is our 1000W amplifier module; its Class-D operation and switch mode power supply offering efficient performance, with little energy wasted as heat.

Comprehensive controls are provided so that the subwoofer can be integrated seamlessly into either a multi-channel or 2-channel installation.
