Bowers & Wilkins Active vented-box subwoofer system

Specifically designed to complement the 300 Series the compact active ASW300 adds the weight and power required to reproduce the special low- frequency effects of movies and the lowest octaves of music. The ASW300 features a 200mm driver with an extremely rigid cone designed to withstand the large forces generated by dynamic bass signals Its output is reinforced by Flowport, B&W’s familiar dimpled design that reduces turbulence noise to negligible levels.
