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.

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).
