Award-winning 251 environmental speakers let you enjoy rich, balanced stereo sound over a much wider area than most conventional outdoor speakers. And 251 environmental speakers are tough enough to beat the weather. These speakers connect to your stereo components or Lifestyle system and mount to your exterior walls.With conventional outdoor speakers, sound can only be heard with impact in a few "sweet spots" instead of the broader range of your patio, pool or yard. But Bose 251 environmental speakers produce remarkably rich sound across a much wider listening area.Vital to that performance is Articulated Array speaker design, which houses two speakers set at precise angles in each enclosure. This produces an extremely wide sound field so that you experience consistent stereo effects as you move around outdoors.The small cabinets of conventional outdoor speakers often can't produce the low notes that provide impact. The 251 speakers blend with your outdoor surroundings, yet their technology and design eliminate the audible distortion often heard in other speakers. You can enjoy full, rich music without the need for large, bulky speakers.
