The Bose 251 Environmental Speakers deliver full, rich sound for your listening pleasure on the deck, by the pool or on the porch. Built to withstand the elements, these award-winning speakers provide reliable, year-round performance that will have you humming in the sun or singing in the rain.
Two 2 1/2" Twiddler drivers in an Articulated Array® speaker design
Lifelike stereo sound over a larger listening area instead of in one small "sweet spot" as with conventional speakers.
One 5 1/4" woofer in a patented multi-chambered bass enclosure
Uniquely structured, the chambers within this patented design filter out unwanted audible distortion in the low-frequency range. They also improve speaker efficiency, resulting in deeper bass from a small enclosure.
Talc- and glass-filled polypropylene cabinet
Added durability against extreme conditions.
Patented multi-chamber bass enclosure for deep bass without audible distortion.
Engineered to withstand snow, sun, rain, ice and saltwater spray.
