DESCRIPTION

Bose had a hit on its hands when it released theAcoustimass-5 to stereo listeners. The Bose Acoustimass-15 transforms the AM-5's dual-cube design from two-channel stereo to five-channel surround sound. Each cube contains a tiny driver that turns on a hinge, allowing you to tailor the proportions of direct and reflected sound to your acoustic setting and listening tastes.Since the satellite speakers are rather small, Bose also gives you a large subwoofer module to beef up the bass, and says it can go pretty much anywhere in the room. Unlike the subwoofer in the less costly AM-10 system, the AM-15's sub is active, meaning self-powered. That in turn makes this system more directly comparable to other sat-and-sub systems on the market, which typically include powered subs. It also makes possible the integrated signal processing that keeps bass at realistic levels whether the overall volume goes up or down.
