Overview

All-around sound for outdoor spaces

Bring the subtle nuances of your favourite music to life in outdoor environments where wall mounting is not an option. Bose® Free Space® 51 speakers are our best performing outdoor speakers for placement in the garden, on the deck or on the patio. Connect them to your existing stereo receiver and enjoy natural sound throughout a broad listening area.

  • 360-degree sound coverage for our widest outdoor speaker coverage
  • In- or on-ground installation for landscape speaker or patio speaker placement
  • Engineered to withstand snow, sun, rain, ice and saltwater spray

Free Space® 51 outdoor stereo speakers offer broad, even coverage from a design that enables 360-degree sound dispersion. A centrally located port enhances low-frequency performance to help preserve the depth and richness of music outdoors. And a domed grille resting over that port reflects high-frequency tones across the listening area.

These speakers can be installed in the ground or on hard surfaces. Designed to blend in with garden greenery, you may hardly notice them when placed within your landscaping. And for use on a patio or deck, the grooves on the underside of the base allow you to neatly tuck in wires for a simple and professional-looking installation.

Rugged construction for year-round use

With all of their features, including a downward-firing, 11.4 cm", full-range driver, these weather-resistant speakers offer the durability you need outdoors with sound you'd expect indoors. Leave them outside all year long—these weather-resistant speakers are engineered and tested to withstand snow, rain, salt and temperature extremes of 60°C (140°F) to -30°C (-22°F). They are also protected by a five-year limited warranty.

Rated 5 out of 5 by from Best outdoor speakers Have had 2 pairs hooked to sonos amp for 3 years now, sound is perfect. Have so many people ask where the speakers are, since they allow sound from every direction with my set up around the pool & patio. One set is ~13 yrs old and the other ~11yrs old. Have survived a few hurricane floods and no damage to speaker or sound. Just had a single one get attacked by ants, and I think they did it in. No doubt in my mind will be replacing it with this same speaker soon.

Rated 5 out of 5 by from Great Speakers, hold up well! I’ve had these speakers at the corners of our spa for over 13 years. They sound great. I haven’t noticed any degradation in sound. I have and old pioneer receiver feeding them. So nice to listen to great sounds at the Spa, while Pandora streams. A great investment!

FAQs

What is the appropriate speaker wire for these speakers?

You must first determine the distance of your speakers from your receiver. That will help you choose the appropriate gauge (thickness) of speaker wire. If your installation requires the wire to be buried in the ground, use direct-burial rated cable or run the wire through a PVC piping channel. Always use moisture-resistant speaker wire.

What conditions and temperature extremes can these speakers withstand?

FreeSpace 51 speakers are designed to withstand:

    • Sun, high humidity (rain and snow), salt and fog
    • Temperature extremes (-40°C to 70°C; -40°F to 158°F)
    • Permanent outdoor installation

Can these speakers be combined with my Lifestyle or SoundTouch system?

Yes. You can combine these with the SA-5 amplifier to expand your Lifestyle SoundTouch entertainment system or SoundTouch home cinema system to a second room or outdoors.

What is the warranty on these speakers?

FreeSpace® 51 speakers carry a five-year limited warranty.
