Selecting the location for your speakers
Prior to installation, carefully select locations for your Free Space
®
51 speakers. The
speakers can be installed on almost any surface such as wood, concrete, or the ground.
When
choosing a location, please keep the following guidelines in mind:

Primary Coverage Area
• Select a level surface for your speakers. This will prevent movement or vibration during use.
• Place your speakers where the speaker cord cannot be tripped over, pinched, or pulled.
• Do not place your speakers in an area where water tends to collect.
• Do not bury your Free Space 51 speakers deeper than 7 1/4 inches (18.4 cm) (Figure 3a).
• Place 2 - 4 inches (5 - 10 cm) of crushed rock or gravel at the base of the hole to allow for
wa
te
r drainage.
• Do not block the drainage opening on the bottom of the speaker.
• Use wood screws to fasten the speaker to a wood surface, such as a deck, if desired
(Figure 3b).

Choosing the speaker cord (not provided)
WARNING: Before running speaker cord through a wall or under ground, check your local
building code requirements, or contact an electrical installer.
• Use the proper gauge (thickness) of speaker cord. See “Cord recommendations” under
“Te
chnical Information” on page 9 for proper gauge, or check with your authorized Bose
®
dealer.
• If your installation requires the cord to be buri
ed in the ground, use direct-burial rated cable
or run the cord through a PVC piping channel. Always use moisture-resistant speaker cord.
• Place speakers and run cord before digging holes or burying cord.
• If you think your speaker cord may be exposed to salt water or water containing chemicals
such
as chlorine or fertilizers, you may use a silicone caulking material as added protection
for the speaker connections.
