B&W (Bowers and Wilkins) ASW CM Active Subwoofer - 500W


Beautiful powered subwoofer for your home theater, in a real wood maple veneer finish.

(We also have the matching B&W CMC Center Channel Speaker available)

This ASW CM Subwoofer is in overall solid working condition, tested in our workshop and also in our listening lab to happy ears and smiling faces via recent Blu-Ray release test discs.

Please be sure to check out all of our photos as this subwoofer does have some scratches and a few corner dings.  

Summary Features:
•  This versatile subwoofer is compact enough not to physically dominate the smaller room, but powerful enough to fill the larger room with powerful, deep bass from either music or movie based sources.

•  The rugged 250 mm (10 in) driver, with its composite paper-Kevlar®-aluminium cone, large magnet and high-power voice coil, can move large volumes of air with exquisite control for accurate low-frequency output.

•  To ensure the driver can perform in the relatively compact cabinet, the subwoofer features a powerful 500W amplifier to apply the necessary equalisation. Equipped with audiophile full-range Class-D circuitry and a switch mode power supply, the amplifier is extremely efficient and operates reliably cool.

Standout features include:
•  Unbalanced stereo RCA inputs and high-passed outputs allow you to pass-through line level signals from sources that do not have a dedicated subwoofer RCA pre-out
•  Standby/Auto/On - selectable (auto signal sensing) power control
•  Control Knobs for Volume and Low-Pass Frequency
•  0 / 180 degree phase selector switch
•  Detachable power supply cord allowing you to use your own from Cardas, AudioQuest, etc.
