WARNING

● 

Each speaker weight 1.76 lbs (0.80kg). Do not mount them on thin plywood or soft 
surface material. If mounted, the screw may come out of the flimsy surface and the 
speakers may fall. This damages the speakers or causes personal injury.

● 

Do not install the speakers to a wall with nails, adhesives, or any other unstable 
hardware.

● 

To avoid accidents resulting from tripping over loose speaker cords, fix them to the wall.

● 

Secure installation is the purchaser’s responsibility.

Please place rubber feet as shown in the diagram 
prior to mounting the speakers on the wall.

Fasten screws into a film wall or wall 

support as shown in the figure, and hang 
the holes of the mounting bracket on the 
protruding screws.

Make sure that the screws are securely 
caught by the narrow sections of the “key 
hole” opening. Main and rear speakers can 
be mounted horizontally or vertically.

Place the center speaker on top of the TV, on the floor under 
the TV or inside the TV rack so that it is stable.
When placing the speaker on top of the TV, put the provided 
Velcro

TM

 strips at two points on both the bottom of the speaker 

and on top of the TV to prevent the speaker from falling.

Notes

● 

Do not place the speaker on top of the TV whose area is smaller than the bottom area of 
the speaker. The speaker may fall and might cause personal injury.

● 

Though this speaker is a magnetically shielded type, there may be some influence on a 
TV picture depending on the type of TV or the placement of the speaker. In such a case, 
place the speaker apart from TV so that there is no influence on TV picture.
