Note: For Stereo Everywhere® speaker performance, horizontal mounting is required.
Note: Your 151® SE speakers can be mounted vertically. However, when mounted vertically you
will not experience Stereo Everywhere® speaker performance.
Note: If you choose to place the speakers on a flat horizontal surface, put a layer of suitable
material (such as rubber) under the speaker to prevent speaker movement or damage to the flat
surface due to vibration of the speaker.
CAUTION: Do not mount the brackets on surfaces that are not sturdy enough, or that have
hazards concealed behind them, such as electrical wire or plumbing. If you are unsure about
installing the bracket, contact a qualified professional installer.
CAUTION: Do not install near any heat sources, such as halogen lamps, registers, stoves or
other apparatus (including amplifiers) that produce heat.
CAUTION: Do not hang items from the brackets or speakers. Do not place items on top of the
speakers. The brackets were designed to support the weight of the speakers only.
CAUTION: The 151 SE speakers are not intended to be installed in automobiles.
Before mounting your speakers
• Check local building codes regarding the installation of outdoor speakers. If you are
uncomfortable about installing this product, contact your Bose dealer to arrange for a qualified serviceman to help you.
• Measure the length of speaker cord needed to connect each speaker to your amplifier. See
“Required tools and materials” for recommended wire lengths and sizes.
• Determine the best route to protect the wire.
• Make sure the speakers cannot fall and cause injuries.
• Keep the speakers at least 9 inches (23 cm) from any video screen or monitor.
Bose 151 SE speakers are not magnetically shielded.

2. Hold bracket part A in position against the wall and mark the left and right round holes for
the mounting hardware (Figure 4). If you plan to feed speaker cord through the wall, mark
the oval speaker cord feed-through hole also.

3. Drill holes using the appropriate drill bits for the wall material. Refer to “Required tools
and materials” on page 3.
Note: If you plan to feed the speaker cord through the bracket, feed the cord through the wall
before mounting the bracket.
4. Mount bracket part A to the wall using the appropriate hardware for wood (G) or concrete
(H and G). Make sure the hole for the bracket locking screw is on your left (Figure 4).
5. Mount bracket part B to the rear of the speaker using two machine screws E and two
lock washers F (Figure 4).

Adjusting speaker angle
Note: Your 151® SE speakers can be mounted vertically. However, when mounted vertically you
will not experience Stereo Everywhere® speaker performance.
Note: For vertical mounting, mount bracket part A so that the hole for bracket locking screw C is
at the lower end of the bracket. When mounted vertically, you can rotate the logo to be read horizontally. Gently pull out on the logo, rotate it into position and release.
Connecting your speakers to your receiver/amplifier
Speaker cord consists of two insulated wires. The wire marked with a stripe or rib is used
for the positive (+) red terminal connection. The plain wire is used for the negative (–) black
terminal connection. Strip approximately ½ inch (1.3 cm) of insulation from the ends of both
wires (Figure 6). Then, twist the ends of each wire so there are no loose strands.
CAUTION: Before making any connections, turn off your receiver/amplifier and unplug it from
the AC power outlet.

1. At the back of your speaker (Figure 6), unscrew the hex knobs on the terminal posts until
you can see the small hole going through each post.
2. Insert the marked (+) wire into the red (+) terminal. Insert the plain (–) wire into the black
(–) terminal. Tighten the knobs to secure the wires.
3. Check the speaker connections carefully. Make sure no loose strands of wire touch
across terminals creating a short circuit that can damage an amplifier or receiver.
Note: After making the connections, any bare lengths of speaker wire can be affected by exposure to the outdoor environment. To protect the speaker wires, apply a thin coating of silicone
caulking material, such as RTV adhesive, to any bare sections of speaker wire.
6. Secure the speaker with bracket part B to bracket part A using bracket locking screw C
and lock washer D (Figure 3). To adjust the angle, loosen screw C slightly (Figure 5),
move the speaker up or down, and retighten screw C.

4. Connect the speaker on the left side of the listening area to the left amplifier channel
(Figure 7). Attach the marked wire to the red (+) terminal. Attach the plain wire to the black
(–) terminal.
5. Connect the speaker on the right side of the listening area to the right amplifier channel.
Attach the marked wire to the red (+) terminal. Attach the plain wire to the black (–) terminal.
Note: If your speakers are being connected to your receiver or amplifier as a secondary set of
speakers, be sure to make the appropriate connections to the “B” channel.

Testing the connections
Set the balance control on your receiver or amplifier to normal (centered) and play some deep
bass passages of music through the speakers. Verify that the sound seems to come from a
point between the two speakers, and that the bass is full and natural. If not, check your connections again; they may be reversed, causing the speakers to play out of phase. Make sure
all the wires are connected positive to positive (+ to +) and negative to negative (– to –).
What to do

2. If your speakers are connected to the “B” output, check that the “B” output is selected.
2. Check the wires connected to the speaker that does not play. Make sure the wires are in good
condition and are firmly connected.
1. Disconnect the working speaker from the receiver or amplifier.
2. Switch the cord of the faulty speaker from its original receiver or amplifier jacks to the other set of
jacks (the working speaker was originally attached to those jacks). If the speaker now works, the
problem is your receiver or amplifier. Reconnect the speakers to a working unit. If the speaker still
does not work, continue.
3. Remove the cord from the working speaker and connect it to the faulty speaker. If the speaker now
works, the original speaker cord is bad. If the speaker still does not work, the speaker is bad.
4. If trouble persists, contact your authorized Bose dealer, who will arrange for service. Or, contact
Bose Customer Service. Refer to the list of phone numbers and addresses included in the carton.
