Bose 161 speakers offer outstanding performance in a design that blends into your decor. Their Articulated Array speaker design reproduces sound over a larger area. Bose Stereo Everywhere speaker performance lets you hear rich stereo sound almost anywhere in the room, instead of one small "sweet spot" as with conventional speakers. Using two proprietary Twiddler drivers in each enclosure, 161 speakers deliver the kind of performance you might expect from much larger speakers. And with their slim elegant design, 161 speakers can be used as part of a stereo system or home theater system. Multipurpose speakers.
