Enjoy a rich, balanced stereo sound over a much wider area than most outdoor speakers thanks to the Articulated Array design. 2 - 2-1/2" speakers and a 5-1/4" driver are set at precise angles in each enclosure to produce an extremely wide sound field, creating consistent stereo effects as you move around outdoors. The multi-chambered enclosures are uniquely structured to eliminate audible distortion from low frequencies. As for Mother Nature, in tests Bose has thrown the most extreme conditions at the 251s. They are built to withstand snow, salt, rain, and temperatures from 140 to -22 degrees F. Their sleek design blends seamlessly into your home's lines. Mounting hardware included.
