These Bose® multi-purpose speakers offer high performance in a slim and elegant design for stereo surround sound use. Stereo Everywhere® speaker performance delivers stereo almost anywhere in the room. Articulated Array® speaker design features two 21⁄2" TwiddlerTM drivers that are angled to reproduce lifelike stereo over a larger listening area instead of one small “sweet spot.” The high-excursion Twiddler drivers generate more air movement from a small enclosure. Custom brackets enable easy mounting for stereo or surround sound use. Compatible with amplifiers and receivers rated 10 to 100 watts per channel. Size: 41⁄8"H x 11"W x 5"D. Available in black or white.
