ONKYO HT-R391 Manual Do Utilizador

We recommend using the supplied rubber stoppers to 
achieve the best possible sound from your speakers. The 
rubber stoppers prevent the speakers from moving, 
providing a more stable platform.

If the subwoofer is placed on a hard floor (wood, vinyl, 
tile, etc.) and playback is very loud, the subwoofer’s feet 
may damage the flooring. To prevent this, place the 
supplied pads underneath the subwoofer’s feet. The pads 
also provide a stable base for the subwoofer.

To mount the front/surround speakers vertically, use the 
keyhole slot shown to hang each speaker on a screw that’s 
securely screwed into the wall.

To mount the center speaker horizontally, use the two 
keyhole slots shown to hang the speaker on two screws that 
are securely screwed into the wall.

• If the center speaker is tilted, loosen the screw on the declined 

side to move upward so that the speaker could be adjusted 
vertically.

• A mounting screw’s ability to support a 

speaker depends on how well it’s 
anchored to the wall. If you have 
hollow walls, screw each mounting 
screw into a stud. If there are no studs, 
or the walls are solid, use suitable wall 
anchors. Use screws with a head 
diameter of 5/16" (9 mm) or less and a shank diameter of 
1/8" (4 mm) or less. With hollow walls, use a cable/pipe 
detector to check for any power cables or water pipes 
before making any holes. 

• Leave a gap of between 3/16" (5 mm) and 7/16" (10 mm) 

between the wall and the base of the screw head, as 
shown (We recommend that you consult a home 
installation professional).
