Product Details

Bowers & Wilkins CM Series 12" Gloss Black Subwoofer, Model ASW12CMGB

For the ultimate in bass production, there is no better choice than the Bowers & Wilkins ASW12CM Subwoofer. Part of the CM Series line of speakers, this B&W subwoofer combines massive bass with an elegant, simplistic design.

The ASW12CM subwoofer employs a switch mode power supply and 500W Class D amplifier to move a 12-inch dual voice coil driver. This long-throw driver is constructed of a paper and Kevlar combination, creating a lightweight cone with unmatched stiffness. These features all work together to create imposing bass, with a frequency range as deep as 18Hz.

Aesthetically mimicking the rest of the CM Series of B&W speakers, the ASW12CM subwoofer is encased in a robust enclosure and wrapped in a majestic gloss-black veneer. Its heft and footprint—nearly two square feet—imbue the ASW12CM with an unshakeable stability, for rattle-free bass production. This hulking B&W subwoofer may look stoic when placed in the corner of your home theater, but once the movie starts you'll hear that it is anything but.
