PAINTING ThE GRILLES
The CM loudspeaker grilles can be painted without priming, but the fabric scrim
must rst be removed. The installation template has die cut standoffs that can be
used to position the grille off the ground while painting. Use several light coats
sprayed from different sides and angles to cover all surfaces and not ll in any
holes. If you do ll some holes, use compressed air to open them before the paint
dries. It may be helpful to slightly dilute the paint to prevent it from clogging the
grille holes.
INSTALLING ThE GRILLES
The Niles MicroThin™ speaker grille installs magnetically over the speaker.
Carefully center the grill over the speaker and let the magnets do their work,
verifying that the grill sets ush against the ceiling at all edges.
APPLICATIONS
The Niles CM7SD Loudspeakers are designed to be installed in any standard
ceiling. When choosing a location, thought should be given to the sound
coverage of the loudspeaker, and ease of running the speaker wire. The shallow
mounting depth of the CM7SD allows it to be mounted in a space that is only
2.75” deep.
STEREO SOUNd APPLICATIONS
The best stereo effect will be achieved if both
loudspeakers are at an equal distance from the
listening area. Ideally all loudspeakers should
be on the same horizontal plane (Figure 6). Avoid
installing loudspeakers near corners to prevent
a “boomy” or diffracted sound. Also note that
the lower the ceiling, the closer the loudspeaker
should be placed to the listener.
