About the Bose® 251® environmental speakers
Take sturdy, weather-resistant outdoor speakers. Provide them with angled drivers in a unique Articulated Array® design that reproduces sound over a larger listening area. Then add top-notch Bose audio technology, with patented multi-chamber bass enclosures for deep bass without audible distortion. The result? Bose 251® environmental speakers and a whole lot of outdoor music enjoyment.
These innovative speakers can withstand temperature extremes from 158º F to -40º F, and passed the rigorous salt fog test 66% longer than required by the Marine Industry Standard. That means they can handle direct exposure to the elements so they make just as much sense for your dock or boat as they do for your patio. And with weather-resistant mounting brackets and hardware included, and a 5-year warranty, you can count on years of groovin' in the great outdoors.

Drivers: The Bose 251 environmental speaker features a 5-1/4" woofer and two 2-1/2" Twiddler drivers with ultra-durable, polymer fiber composite cones built to withstand temperatures from a blistering 158° F to a frigid -40° F. Additionally, the speaker can withstand salt fog, sun, high humidity (100% RH), vibrations and mechanical shock.
Articulated Array Speaker Design: By precisely positioning the drivers inside the speaker cabinet, an Articulated Array speaker design can provide a large, consistent sound field. This allows for a more even sound coverage with these outdoor speakers.
Water-Resistant Cabinet: Engineered with a water-resistant, weather-tight polypropylene housing, these speakers provide extra durability through extreme weather conditions and still deliver great high-fidelity sound. For additional protection, the speaker uses a galvanized, powder coated steel grille.
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.
5-Way Binding Posts: The nickel-plated brass 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.
Mounting: Weather-resistant mounting brackets are also included to allow for easy installation. The speakers can be moved up and down in the mounting brackets, allowing you to position them for optimum imaging.
