If your TV is placed on a table, you can place the soundbar on the
table directly in front of the TV stand, centered with the TV screen.
As long as the surface of the table is flat, the soundbar will rest on its
rubber bumpers.

If your TV is attached to a wall, you can use the included wall-mount
brackets to mount the soundbar on the wall directly below the TV
screen.
1. Determine the location for the soundbar on the wall. Make sure
that the top of the soundbar will not block your view of the TV
screen when it is mounted on the wall.
2. Mark the locations of the soundbar wall-mount bracket holes on
the wall. The holes for the left and right brackets are spaced
30-5/16” (770mm) apart, and are designed to accept 4mm
diameter screws. The top and bottom holes for each bracket are
spaced 1” ( 25mm) apart. See the illustration below.
30-5/16" (770mm)
1" (25mm)
(not to scale)
NOTE: To ensure that the soundbar will be level, use a carpenter’s
level, laser sight or other device to ensure that the two sets of holes
are at exactly the same height.
3. Attach the two wall-mount brackets to the wall at the locations
you marked, using hardware that is appropriate for the wall’s
construction and materials. Note that the soundbar weighs 2.5kg
(5.5 lb). Be sure to use hardware that can support this weight.
4. After making all of the connections described in the Connections
section, on page 5, attach the soundbar to the brackets by sliding
the brackets’ vertical tabs into the slots in the soundbar’s rubber
bumpers.

The performance of a subwoofer is directly related to its placement
in the listening room and its physical position relative to the other
speakers in the system.
While it is true that in general, our ears do not hear directional sounds
at the low frequencies where subwoofers operate, when installing
a subwoofer within the limited confines of a room, the reflections,
standing waves and absorptions generated within the room will
strongly influence the performance of any subwoofer system. As
a result, the specific location of the subwoofer in the room does
become important to the amount and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will
increase the amount of bass in the room; placing it in a corner ()
generally will maximize amount of bass in the room. However, corner
placement can also increase the destructive effect of standing waves
on bass performance. This effect can vary depending on the listening
position – some listening positions may yield very good results,
while others may have far too much (or too little) bass at certain
frequencies.
In many rooms, placing the subwoofer along the same plane as the
soundbar () can produce the best integration between the sound of
the subwoofer and that of the left and right speakers. In some rooms,
the best performance could even result from placing the subwoofer
behind the listening position ().

We strongly recommend that you experiment with placement before
choosing a final location for your subwoofer. One way you can
determine the best location for the subwoofer is by temporarily
placing it in the listening position and playing music with strong
bass content. Move around to various locations in the room while
the system is playing (putting your ears where the subwoofer would
be placed), and listen until you find the location where the bass
performance is best. Place the subwoofer in that location.
IMPORTANT: The maximum wireless operating distance between the
soundbar and subwoofer is approximately 50 feet (15.3m).
