INTRODUCTION
Thank you for selecting the Russound Contractor Series In-wall/In-ceil-
ing Speakers. Like all Russound speakers, they combine acoustic technol-
ogy with durability and will provide years of musical enjoyment. An
added feature of models SP-C503, SP-C522 and SP-C622 is the dual
voice coil design. This is unique in that both left and right signals can
function in one speaker, which is ideal for smaller installations or where
there is no preferred listening position.
Russound Contractor Series speakers should only be installed by autho-
rized personnel.
SPEAKER WIRE
The amount of wire you’re going to need will of course vary with speak-
er placement. We recommend labeling speaker wires with “left” and
“right” and room location. This takes the guesswork out of which wires
go where when installing speakers later.
What kind to use:
We recommend using Russound AW series speaker cable or any rep-
utable brand of 16 to 12 gauge multi-stranded wiring for amplifier-to-
speaker connections.
Selecting the proper gauge:
Wire is measured in gauges: the bigger the number, the smaller the
wire. For example, 18-gauge is thinner than 14-gauge. The gauge of
wire you need is determined by the distance between your
amplifier/receiver and the in-wall speakers. Remember, the longer the
run, the heavier the gauge needed. Use the following chart as a guide:
Length Minimum Gauge
0 to 100 ft. 16
50 to 150 ft. 14
100 to 200 ft. 12
WHERE TO PLACE YOUR CEILING SPEAKERS
Placement can make all the difference in how your Russound speaker
system sounds. There are at least four factors to consider for your
layout:
• How you intend to use the ceiling speakers
• Where they’ll sound best (stereo imaging and acoustic considerations)
• Where they can be installed (wall and ceiling surfaces)
• Where speaker wire can be run
STEREO IMAGING
If your Russound Ceiling Speakers are going to be your primary listening
source in a room, you need to consider some other factors to insure
proper imaging. The term “stereo imaging” refers to a speaker system’s
ability to project music so that it sounds like the performers are in a
three-dimensional space between the speakers. It’s the whole point of
having stereo instead of monophonic sound.
OTHER ACOUSTIC CONSIDERATIONS
For best fidelity, there are several other factors to keep in mind before
you start actual installation.
