SPeaker Placement

PLaciNg tHe sOuNdBar ON a taBLe 

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.

Determine the location for the soundbar on the wall. Make sure that 

1. 

the top of the soundbar will not block your view of the TV screen 

when it is mounted on the wall.
 Mark the locations of the soundbar wall-mount bracket holes on the 

2. 

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.

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.

Attach the two wall-mount brackets to the wall at the locations 

3. 

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.

After making all of the connections described in the 

4. 

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 (

1

) 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 (

2

) 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).
