Unpacking the carton
Thank you for purchasing your Bose® Free Space® 51 speakers. These high-performance
outdoor speakers are engineered to provide sound quality far beyond that of most outdoor

come (see “Environmental capabilities”, page 9).
Carefully unpack your Free Space 51 speakers and save all packing materials for possible
future use. Check that your sys tem c ont ains a ll part s id en tifi ed in Fig ure 1. Do not attempt to
use your speakers if any components are missing or appear damaged. Inst ead, notify Bose

Prior to installation, carefully select locations for your Free Space® 51 speakers. The
English
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:
• 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
te
r drainage.

• Do not block the drainage ope ning on the bo tto m of th e speaker.

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
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 connect ions.

Stripping the wires
WARNING: Before making any connections, turn off your receiver or amplifier and unplug it
from the AC power (mains) outlet.
Preparing the speaker cord
Speaker cord consists of two insulated wires. Usually one is ribbed or red (+), and the other
plain or black (–). Direct-burial cable has a protective outer jacket around the wires.
Consider the following guidelines
• Measure the length of cord needed to connect each speaker to your receiver/amplifier
• Strip the outer jacket back 2". Strip the inner insulation on both wires back

Reinforcing the wire nuts
Connecting the speaker cord to the speakers
1. Connect the positive (ribbed or red) speaker wire to the positive (red) wire from the
speaker cable. Twist the stripped wires together.
2. Secure the wire nuts with a twisting motion. If you prefer to reinforce the wire nuts, use
elec
trical tape (Figure 5).
3. Connect the negative (plain or black) wire to the negative (black) wire from the speaker
cable, as in steps 1 and 2 above.
Connecting the speaker cord to the receiver/amplifier

Checking the connections
Check the speaker connections carefully. Make sure no loose strands of wire touch across
terminals. This could create short circuits and damage an amplifier or receiver.
Tighten any loose connections before you plug in the receiver/amplifier.

Testing the connections
To make sure your speakers operate correctly, follow these steps:
1. Center the balance control on your receiver/amplifier.
2. Set the stereo/mono control to MONO.
3. Play some passages of music containing deep bass through the speakers.
The sound should seem to come from a point between the two speakers. The bass should be
ll a
nd natural. If not, the connections may be reversed, causing the speakers to play out of
fu
phase. To correct the problem, make sure all the cords are connected positive to positive (+
to +) and negative to negative (– to –).
