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" (8 mm) or less 
and a shank diameter of 1/8" (4 mm) or less. With hol-
low walls, use a cable/pipe detector to check for any 
power cables or water pipes before making any holes.
• (HTP-680) Leave a gap of between 5/32" (4 mm) and 
5/16" (8 mm) between the wall and the base of the screw 
head, as shown.
(HTP-780) 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.)
We recommend using the provided stoppers to achieve the 
best possible sound from your speakers. The stoppers pre-
vent the speakers from moving, providing a more stable 
platform. 
■ SKF-680, SKR-680, SKB-680, SKC-680
Use rubber stoppers for the speakers.
■ SKC-780
Use cork stoppers for the center speaker.
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 sup-
plied pads underneath the subwoofer’s feet. The pads also 
provide a stable base for the subwoofer.
