Cambridge SoundWorks MC300IW In-Wall LCR Loudspeaker - Manual (Page 7)

1. Decide where you want the MC300IW speakers to
be placed. Using a stud-finder (or other means),
locate the nearest wall stud adjacent to this loca-
tion. Adjust your loudspeaker placement so that the
necessary wall cutout will not intersect the stud.
The resulting wall cutout should be at least 1/2"
away from any stud. When you are using the
MC300IW horizontally as a center channel there is
very little room for error.
2. Use the supplied template to scribe the area to be
cut out. It is recommended that a level or other
device be used to square the template to other
reference points within the room. While there is
some degree of freedom to adjust the speaker in
the hole, it is best to have a level mounting hole to
begin with.
3. Remove the cutout area using your preferred tool.
If you are cutting into a wall or ceiling with a plaster
skim-coat, drill a small hole at each corner first to
reduce the chance of a spreading crack.
Note: When cutting into a wall or ceiling, be careful
not to cut into items such as wiring, conduit, or
plumbing. It is often difficult to know exactly what
lies behind a cutout area. If you are not certain, first
make a smaller (3/4" – 1") inspection hole in the
center of the cutout using a drill. Using a flashlight
and a probe, inspect the area behind the wall
before making your final cut.
4. If your cut is on an outside wall, the wall will most
likely contain some form of insulation. Fiberglass
batting type insulation should be left in place, as it
is sonically desirable and will hold its own shape.
Blown-in cellulose or loose glass fibers must be
removed from the area behind the speaker, as they
will get agitated by the speakers’ vibration. If your
wall contains this type of loose insulation, remove it
from the area immediately behind the speaker and
replace it with a pad of fiberglass batting which is
at least 50% larger than the cutout in each direc-
tion. Also, if you are locating the speaker on an
inside wall, installing fiberglass batting in the space
between the studs is recommended, as it will
provide an improvement in sound quality.
