251® environmental speakers Speakers that have you covered With conventional outside speakers, stereo sound can be heard in only a few "sweet spots" & not throughout the broader range of your patio, pool or yard. & they often can't reproduce the low frequencies that provide impact. But innovative Bose® 251® environmental speakers use an Articulated Array® speaker design to produce an extremely wide sound field. Each outside speaker cabinet houses two speakers set at precise angles so you experience consistent stereo effects as you move around outdoors. & the unique multi-chambered design of the Bose® 251® exterior speaker cabinet minimises audible distortion from low frequencies, for sound with clear, natural impact. Bose® outdoor speakers are designed for harsh conditions. These weather resistant speakers are engineered & tested to withstand snow, rain, salt & temperature extremes of 60 °C to -30 °C. They are also protected by a five-year limited warranty. * Our best wall-mount outdoor speakers * Extremely wide sound field for larger outdoor areas * Outside speaker cabinet designed to reproduce low frequencies with minimal audio distortion * Tested to withstand snow, rain, salt & extreme temperatures * Five-year limited warranty
