Bower & Wilkins - AS2 Subwoofer speaker set

The Bowers & Wilkins AS2 is a compact and powerful active subwoofer, originally designed as part of the highly acclaimed Mini Theatre series. What makes this subwoofer unique is the integration of the control knobs on the top of the enclosure for easy operation. The extremely stiff 10-inch Mica cone driver is driven by a hefty 150-watt amplifier. Thanks to B&W's patented Bass Overload Suppression System (BOSS), nuisance distortion during unexpectedly loud movie explosions is effectively prevented, resulting in crystal-clear and extremely tight bass response.

Specifications:
Frequency Range (-6dB): 20 Hz – 140 Hz
Frequency Response (±3dB): 32 Hz – 125 Hz
Signal-to-Noise Ratio: > 90 dB

The subwoofer works perfectly.
