Installing the front, center,
and surround speakers
Front speakers:
Place the two front speakers on the
left and right sides of the TV facing directly forward.
Surround speakers:
Place the left and right
surround speakers behind your listening position,
facing slightly inward.
The front and surround speakers can be placed on a
flat surface or wall- mounted.
See “Wall-mounting the speakers” for more
information.
Center speaker: Place the center speaker centrally
between the front speakers, facing directly forward.
Installing the subwoofer
Place the subwoofer on the outside of either the right
or the left front speaker, as shown in
A and B .
The placement shown in C is also possible, however, if
the subwoofer is placed directly facing a wall and your
listening position is in the center of the room, you may
not be able to obtain enough bass sound from the
subwoofer. This is because “standing waves” are
forming between the two parallel walls and cancelling
out the bass sounds. In this case, position the
subwoofer at an angle to the wall. It may be necessary
to break up parallel wall surfaces by placing
bookshelves, etc., along them.
Wall-mounting the speakers
You can mount the speakers on the wall as follows.
1
Install screws into a solid wall or wall support
as shown below. Use 3.5 to 4 mm (1/8")
diameter self-tapping screws.
2
Hang each speaker by its keyhole slots onto
the protruding screws.
Note
• Make sure the shaft of the screw is seated in the
narrow part of the keyhole slot. Otherwise, the
speaker may fall.
Warnings
• NS-B40 speaker weighs 0.59 kg (1.30 lbs.) and NS-
C40 speaker weighs 0.73 kg (1.61 lbs.). Do not
mount the speakers on thin plywood or on a wall
with a soft surface material. Otherwise, the screws
may pull out of the surface and the speakers may fall,
possibly damaging the speakers or causing personal
injury.
• Do not affix the speakers to a wall using nails,
adhesives, or unstable hardware. Long-term use and
vibration may cause the speakers to fall.
• To avoid accidents resulting from tripping over loose
speaker cables, affix the cables to the wall.
• Mount the speakers in a wall location that will be
unlikely to result in injury to an individual’s head.
