The performance you want. The reliability you need.
The award-winning Bose® 251® environmental speakers brings a new standard for performance and reliability to your outdoor listening experience. By using the Articulated Array® speaker design helps to reproduce sound over a larger listening area. And with the patented multi-chamber bass enclosure helps deliver full, deep bass without audible distortion, from a smaller design.
The products of rigorous testing.
The Bose® 251® Environmental Speakers are engineered and tested to withstand snow, rain, salt – even temperature extremes of 140° F to -22° F, the 251® environmental speakers deliver performance and reliability most conventional outdoor speakers – and many indoor speakers – simply cannot match. Weather-resistant mounting brackets and hardware are also included to allow for easy installation.
A simple expansion solution.
Combine the 251® environmental speakers with the Bose® Lifestyle® SA-1 stereo amplifier and bring the performance and simplicity of your Lifestyle® system outdoors. Want to enjoy music on the porch or patio, or maybe by the pool? A simple connection to the Lifestyle® SA-1 stereo amplifier, which was designed to expand Lifestyle® systems to the outdoors with our environmental non-powered speakers, is all you need to power your 251® environmental speakers and deliver rich, lifelike sound outside. It's that easy. So, why leave the music indoors?
