The Bose 161 speaker system offers the ideal combination of outstanding performance and elegant, unobtrusive design. You hear rich, full music from speakers designed to blend easily into any room decor. Two key technologies allow 161 speakers to bring you such high-performance sound from a small enclosure. Two proprietary Twiddler drivers in each speaker help deliver the kind of performance you'd expect from much larger speakers. And our Articulated Array speaker design enables Stereo Everywhere speaker performance for lifelike stereo sound almost anywhere in the room, not just in one "sweet spot."
