With enhanced performance, revitalized styling and smaller, sleeker cabinets, the industry's most popular outdoor speaker is now even better. The Bose® 151® SE environmental speaker system features Stereo Everywhere® speaker performance for balanced stereo sound over a wide area instead of in a small sweet spot to accommodate the way people enjoy listening outdoors. Slot-port tuning provides deep low-note performance that remains clean, even at high volumes. Compact, contoured cabinet mounts horizontally or vertically and blends unobtrusively into the environment. Rugged design and enclosure withstand harsh weather from season to season, year after year. Backed by a comprehensive five-year limited warranty.
