INSTALLATION CONSIDERATIONS
We recommend using the following tools and material to install your Niles CM loudspeaker:
• Cordless drill with 1/4 – and 1/2inch drill bits and a 1-inch paddle
drill bit (for drilling through studs)
• Stiff wire, fish tape or glow rods
for routing cables
• Rubber gloves and protective
eyewear
Before starting the installation, please observe the following precautions:
• Turn off all system power before
making any connections
• Always wear protective eyewear
when using tools
RUNNING WIRES IN WALLS OR CEILINGS
When running loudspeaker wire inside walls or ceilings, use special jacketed cable (a minimum of 18 to 16-gauge two-conductor CL-2
or CL-3 rated loudspeaker wire) to protect the wire and for fire prevention. In some areas, conduit is also required. For a trouble-free
installation, low-voltage wire such as loudspeaker wire must be run in accordance with the National Electrical Code and any applicable
provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a
professional audio/video installer, building contractor, or the local building and inspection department.
SELECTING THE LOCATION FOR YOUR LOUDSPEAKERS
The CM730DSFX, CM750DSFX or CM760DSFX loudspeakers are designed to be installed in any standard ceiling. There are two
considerations for placing the loudspeaker; ease of running the cable to the loudspeaker and coverage of the loudspeaker. The
CM730DSFX, CM750DSFX or CM760DSFX will be most convincing if both of the loudspeakers are at equal distance from the listener.
Avoid installing the loudspeakers near corners to prevent a “boomy” or diffracted sound. The CM730DSFX, CM750DSFX or CM760DSFX
loudspeakers will cover an area of a circle with a 16-foot diameter when mounted at an 8-foot height and pointed straight down.

EXISTING CONSTRUCTION INSTALLATION
IMPORTANT: BEFORE YOU CUT INTO ANY WALL, REVIEW THE PRIOR SECTION ON LOUDSPEAKER PLACEMENT WHEN SELECTING THE
LOCATION FOR YOUR LOUDSPEAKERS.
1. When determining the location of the loudspeaker cutout, keep in mind that the mounting dogs will extend 3/4" beyond the cutout.
Make sure that you do not place the edge of the cutout directly next to a ceiling joist. Locate the joists using a stud sensor or by hand
knocking. Use the supplied cutout template (remove the largest perforated circle and use cardboard square with hole as the template) to
determine how large of a hole you will need to cut. These templates are packed with your loudspeakers between the styrofoam packing
and the ends of the box.
2. Once you have determined a possible position for the cutout, drill a 1/8" pilot hole just barely through the ceiling (1/2" to 5/8" deep in
most homes) in the center of your proposed loudspeaker location.
BE VERY CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU
ARE DRILLING, STOP.
