Corners and Reflections:
When a ceiling speaker is placed close to the corner of a room, bass fre-
quencies are emphasized. This is fine if both speakers are mounted near
corners (while maintaining stereo imaging), but try to avoid placing just
one speaker in a corner and another on a long flat surface. In general,
the best acoustic performance will result if both speakers face a similar
type of surface and are placed in similar positions on the same type of
wall or ceiling.
Installation:
When installing the speakers, avoid:
• T-bar “drop ceilings” with very thin fiberboard panels which can buzz
and vibrate. If you suspect this will happen, reinforce the drop-in
panel with wood or particle board.
• Any wall which can’t provide proper depth (clearance) for the back of
the Russound speaker. This includes brick or concrete walls where the
wallboard or paneling is attached to thin furring strips.
• Inside wall space less than 10” wide and 24” in height
• Ceilings and walls where you know that there are pipes, heating
ducts and ESPECIALLY AC wiring in the general vicinity. For example,
if there is an outlet along the baseboard, there is often a live wire
running partly up the wall at that point. The same applies for ceiling
fans, overhead lighting, etc.
SPEAKER WIRE PATHS
In general, you should pay particular attention to the following areas:
• Avoid running speaker wires close to house electrical wiring for any
distance. If you have to run them parallel, make sure to space the
speaker wires at least two feet from the AC line. It is permissible for
speaker wires to cross paths with AC lines or go through the same
hole together with house wiring if they separate before and after.
• Make sure that the entire path between speakers and amplifier is
clear and not obstructed by a floor or ceiling joist or masonry wall
which you won’t be able to drill through.
• Remember that the other end of the wires has to come out some-
where to connect with the amplifier. Confirm ahead of time that you
can drill an outlet hole easily and in an unobtrusive spot.

Russound ceiling-mount speakers may be used for rear surround sound
channels by placing them (1) behind, (2) on each side of the viewing
position or (3) in the ceiling just behind the viewers. The available
SP-C550 and SP-C650 speakers also make excellent, unobtrusive front
channel home theater speakers for 5-channel listening (4,5).
Optimally, Russound wall-mount speakers should be located with the
tweeters at ear level when the listener is seated.
