Our best wall-mount outdoor stereo speakers deliver balanced stereo sound over a much wider area than most conventional outdoor speakers. And these award-winning exterior speakers are guaranteed to withstand harsh weather.

Mount 251 environmental speakers to your exterior walls, connect to your stereo components or Lifestyle system and SA-3 amplifier, and enjoy quality Bose sound across a much wider listening area.

Speakers that have you covered

With conventional outside speakers, stereo sound can be heard in only a few "sweet spots" and not throughout the broader range of your patio, pool or yard. And 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. And 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 and tested to withstand snow, rain, salt and temperature extremes of 60 °C to -30 °C. They are also protected by a five-year limited warranty.

Bring Lifestyle system performance outdoors

If you own a Lifestyle system, simply add the 251 environmental speakers/SA-3 amplifier package to bring Lifestyle system performance outdoors. Experience a patio speaker that brings music to the pool, the decking or wherever you like to listen outside, even while the same Lifestyle system plays different music or movies indoors.
