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, fi sh 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 16-gauge two-conductor CL-2 or CL-3
rated loudspeaker wire) to protect the wire and for fi re 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 CM700DS series 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 best stereo effect will be achieved if both
the loudspeakers are at equal distance from the listener and closer together than the listener is from the loudspeakers. Avoid installing the
loudspeakers near corners to prevent a “boomy” or diffracted sound. The CM700DS series loudspeakers will cover an area of a circle with
a 16-foot diameter when mounted at an 8-foot height and pointed straight down. (See Figure 1)

• Keyhole or drywall saw

• Phillips screwdriver set

• Wire stripper

• Stud fi nder

• Cable ties

• Pencil

• Make sure hands are clean before
installation

• Wear gloves when working with
fi berglass insulation

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.
