Overview: The Niles Audio CM7PR Ceiling Mount speaker is designed for
primary and secondary listening rooms, and home theater applications. It can be
used as a left or right speaker in a stereo configuration, or left, center, or
right in a home theater application. The CM7PR comes with a magnetically-attached paintable
Note: The CM7PR is packaged as a single speaker.
Drivers: The CM7PR has a rigid 7" glass fiber cone
woofer. The integrated woofer/baffle design enhances the low frequency response,
and allows you to mount a 7" speaker in locations where many competitor's
speakers with the same frame diameter can only use a 6-1/2" driver. The 1"
fluid-cooled Teteron dome tweeter provides smooth highs and a
focused high frequency sound. The proprietary bridge-mounted pivoting tweeter adjustment
lets you aim the sound up to 20° in any
Grille: The CM7PR includes a 10" diameter MicroThin grille,
attaches magnetically to the speaker. The 1/4" thick grille is easy to install,
and blends with the room's aesthetics. It is rust-resistant, and paintable to match any décor.
SG7C square grille is also available, if desired.
Treble Switch: The CM7PR has a 3-position switch that allows
you to adjust the output of the tweeter to compensate for room acoustics. For acoustically
bright rooms with wood or tile floors, you should move the switch to the minus
(-) position to reduce the tweeter output by 3dB. For rooms with carpet,
drapery, and plush furniture--surfaces that absorb high frequencies, you should
move the switch to the plus (+) position to increase the tweeter output by 3dB. The
center position (0) does not affect the tweeter's output.
Weather-Resistant: The frame, speaker, and grille are
weather-resistant, so you can install the speaker in moist environments,
including bathrooms and outdoors under eaves.
Speaker Terminals: The CM7PR is equipped with spring clip
terminals, which can accept up to 12-gauge
speaker wire. For wire runs of less than 80 feet, 16-gauge wire is recommended.
You should use 14-gauge wire for runs of 80-200 feet, and 12-gauge wire for runs
over 200 feet.
Note: When running speaker wire inside walls or ceilings, special
jacketed cable (CL-2 or CL-3) should be used to protect the wire and for
fire prevention. If unsure, you should consult your local building
inspectors about code compliance requirements.
Installation: Installing the speaker requires a 8-1/2"
cutout. The speaker requires a depth of
3-3/4" behind standard 5/8" drywall. There are three spring-loaded
mounting clamps with screws that tighten from the front.
