Bowers & Wilkins Active vented-box subwoofer system

The AS1 is a compact active subwoofer, designed to provide deep bass extension in home theatre and hi-fi applications that incorporate the other speakers in the B&W Leisure Monitor range, the VM1, LM1, and M1. Despite its muscular 85 watts the AS1 is compact enough to take up a discreet, out-of-the-way position on the floor of the typical livingroom. It includes B&W’s Flowport and a music/movie switch that modifies the subwoofer’s output to precisely fit the demands of each type of material. The AS1’s controls are easily accessible, being located on the top panel, rather than hidden at the rear.
