Experience enhanced sound from Bose's most affordable, next-generation Acoustimass stereo speakers. The Acoustimass 3 system delivers bass that's the deepest and fullest yet. Two single-cube speakers--smaller than ever before--are elegantly designed to fit virtually any decor. And the module easily hides away behind furniture or off in a corner, so all the lifelike sound seems to flow from the tiny cubes. When you hear the Acoustimass 5 Series III speakers, you'll think you're listening to much larger speakers. Yet the spacious sound actually comes from two tiny cube speaker arrays and a hideaway Acoustimass bass module. The improved cube speakers offer enhanced performance, contemporary styling, and a smaller size than the Series II. And the improved module fills a room with even deeper, fuller bass. These Virtually Invisible speakers are the definitive answer to the question of how to combine spacious sound with space-saving design. Though the Virtually Invisible speaker design may seem like a disappearing act, the performance is quite noticeable. Full, resonating bass and crystal-clear highs envelop a room in beautiful stereo sound. It's all the result of years of intense research and testing. The Acoustimass 5 speakers accomplish what no conventional speakers can claim: big, lifelike sound without big, bulky speakers. Now or in the future, Acoustimass stereo speakers can be turned into a home theater set by simply adding the compatible Bose VCS-10 center-channel speaker. For full five-speaker surround sound, add the VCS-30 center-surround speaker package.
