Bose® Free Space® 51 environmental speakers
Our take on the Bose® Free Space® 51 environmental speakers by Crutchfield's Julie Govan
The Free Space® 51 environmental speakers are yet another example of Bose®'s commitment to making great sound possible just about anywhere. They're perfect for placement in a garden or backyard, so you can enjoy your favorite music outdoors. And you don't have to worry about placing the speakers in a protected spot constructed of ultra-durable green plastic, these sturdy speakers are ready to handle the toughest weather and sound good doing it.
Bose's innovative radial design lets each speaker disperse sound in a 360º pattern, while protecting the weather-resistant driver no worries about finding the perfect "sweet spot" for listening. Plus, these rugged, flexible 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. They're designed for placement flexibility, too they can be placed on or around decks or patios, secured in-ground, mounted onto hard surfaces, or just left free-standing. And with a 5-year warranty, expect years of expansive outdoor music.

Downward-firing 4-1/2" Full-range Drivers: Each woofer cone combines a pulp and plastic mixture with waterproofing agents for high-quality sound reproduction that is resistant to the type of deterioration often caused by extreme conditions. Because the drivers are downward-firing, they are further protected from the elements to help deliver high fidelity, long-lasting sound. Each woofer uses a treated cloth surround.
Radial Design: The Free Space 51 speakers offer exceptionally broad, even coverage thanks to a radial design that enables 360-degree sound dispersion.
Environmentally Tested: While all Bose speakers are thoroughly tested, the extreme demands placed on outdoor speakers require an even more rigorous evaluation. Bose engineers re-create extreme environmental conditions, like exposure to sunlight, rain, heat, ice, even corrosive salt and fog. They also simulate years of exposure to these conditions to ensure that these speakers can deliver reliable, long-lasting performance.
Green Speaker Enclosures: The speaker enclosures blend in with backyard greenery.
Centrally Located Ports: The centrally located port on each enclosure enhances low-frequency performance to help preserve the depth and richness of your favorite music outdoors.
Domed Port Grilles: Positioned over the centered port, this grille reflects high-frequency tones into the listening area to help deliver clear, consistent performance.
Wire Grooves: Wire grooves on the bottom of each speaker enclosure prevent the speaker from rocking on the speaker wire and enables a professional-looking installation on decks, patios and other flat surfaces.
Base Flanges with Mounting Holes: The mounting holes in each base flange provide easy, solid and secure installation on hard surfaces or in the ground.
In-ground Installation: Each speaker can be buried up to 7-1/4" in the ground. With the speakers buried, 7-5/8" of each enclosure will remain above ground.
