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).
The Home Theater means that you can enjoy surround
sound with a real sense of movement in your own home —
just like being in a movie theater or concert hall.
Front left and right speakers (SKF-791)
They should be positioned facing the listener at about
ear level, and equally spaced from the TV. Angle them
inward slightly so as to create a triangle, with the
listener at the apex.
Center speaker (SKC-791)
Position it close to your TV (preferably on top) facing
forward at about ear level, or at the same height as the
front left and right speakers.
Surround left and right speakers (SKR-780)
Position them at the sides of the listener, or slightly
behind, about 2 to 3 feet (60 to 100 cm) above ear
level. Ideally they should be equally spaced from the
listener.
Surround back left and right speakers (SKB-780)
These speakers further enhance the realism of surround
sound and improve sound localization behind the
listener.
Position them behind the listener about 2 to 3 feet (60
to 100 cm) above ear level.
Subwoofer (SKW-791)
The subwoofer handles the bass sounds of the LFE
(Low-Frequency Effects) channel and bass from the
satellite speakers when a crossover is specified. The
volume and quality of the bass output from your
subwoofer will depend on its position, the shape of
your listening room, and your listening position. In
general, a good bass sound can be obtained by
installing the subwoofer in a front corner, or at one-
third the way along the front wall, as shown.
Speaker Connection Precautions
Read the following before connecting your speakers:
• Turn off your receiver before making any connections.
• Pay close attention to speaker wiring polarity.
Connect positive (+) terminals to only
positive (+) terminals, and negative (–)
terminals to only negative (–) terminals. If the
speakers are wired incorrectly, the sound will be out of
phase and will sound unnatural.
• Be careful not to short the positive and negative wires.
Doing so may damage your amp.
Note
When you connect the front high left and right speakers, prepare
for it separately, or use the surround back left and right speakers.
Caution
• With other audio-video components, connect the
subwoofer’s LINE INPUT to the subwoofer pre out jack
of your equipment. Never plug any kind of musical
instrument to the subwoofer.
