Using the Rubber Stoppers for a More Stable
Platform
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.
Using the Floor Pads for Subwoofer
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.
Wall Mounting
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.
Tip
• If the center speaker is tilted, loosen the screw on the declined
side to move upward so that the speaker could be adjusted
vertically.
Caution
• 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).
