Installing the surround speakers
Place the left and right surround speakers
behind your listening position, facing slightly
inward.
When placing them on a flat surface (hard
floor, etc), affix the supplied non-skid pads to
the corners of the bottom of the speaker as
shown left (Fig. A). The pads will prevent the
speaker from moving around.
When wall-mounting them, affix the supplied
non-skid pads to the lower corners of the back
of the speaker as shown left
(Fig. B). For details, see “Wall-mounting the
speakers”.
Wall-mounting the speakers
You can mount the center and surround
speakers on the wall as follows.
1
Install screws into a solid wall or wall
support as shown left. 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
• Each speaker weighs 1.8 kg (4.0 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.
• When using speaker brackets (commercially available) to mount the speakers on the wall or ceiling, we strongly
recommend using safety wire (may be supplied with the bracket) between the speaker and bracket to prevent the
speaker from falling.
• If you are not sure of a safe way to install these speakers, consult a professional installer or a building contractor.
