The Homewide powered speaker system sets a new standard in Bose\xae multi-room expansion. You can experience the full sound quality of your Lifestyle\xae system in another room with tiny, but powerful, Jewel Cube speakers. Only 4\xbd\" high, they deliver a level of sound you'd expect from speakers many times larger. A powered Acoustimass module provides emphatic low notes for dramatic movie effects and beautiful depth in your music. Together, the speakers and Acoustimass module ensure our highest level of stereo performance.\n\nThe quality sound you experience is customized to your room with the ADAPTiQ audio calibration system. This proprietary technology accounts for the unique acoustic characteristics of your room. And it allows for freedom of speaker placement while assuring consistent audio performance.\n\nYou'll control it all with the Personal\xae music center III remote (NOT INCLUDED). This easy-to-use remote lets you select any device set up to work with your Lifestyle\xae system and adjust its audio playback in your expansion room.
