The Bose Acoustimass 5 Series III Speaker System (Black) features two cube array speakers and one Acoustimass subwoofer module. It's designed for use with your stereo or home theater receiver, but it can also be used as a rear speaker system in your component home theater setup. Its small size allows it to harmonize with your decor and the automatic protection circuitry stops the speakers from being overdriven, which affords added reliability. Plus, with magnetically shielded speakers, you can place them near your TV without worrying about interference to the picture quality.
