This will prevent the gypsum in the drywall from
being knocked loose from speaker vibration. Do
not allow the edge of the masking tape to
protrude more than ¼” beyond the cutout on the
outside wall surface. Masking tape within ¼” of
the cutout will be hidden by the speaker frame.
If the wall contains insulation, remove the
insulation at the cutout and approximately 1 foot
above and below it. This ensures adequate air
volume for the M-CS to operate. Secure any
loose insulation above the cutout.
If the wall is not insulated, it is recommended
that the wall cavity is stuffed with approximately
2 feet of fiberglass insulation both above and
below the cutout, starting at about 1 foot above
and below the cutout. The insulation will provide
damping to the speaker and isolate vibrations.
Speaker Wire
In wall speakers should be connected to the
amplifier with UL rated CL2/CL3 speaker wire –
this is required by building code for most
consumers. Avoid installing speaker wire in
parallel with household AC wiring to avoid
potential hum. It is okay for speaker wire to
cross AC wiring at a right angle, however.
It is recommended that a professional or
licensed electrician perform the speaker wire
installation if you are uncomfortable with the task.
The gauge or thickness of the speaker wire can
affect the performance of the M-CS. Always
choose a CL2/CL3 rated in-wall speaker wire of
the appropriate gauge to prevent excessive
speaker wire resistance. Using undersized
speaker wire can result in lose of volume, detail,
and dynamic range. Please select speaker wire
for the M-CS based on the following minimum
recommendations:
50' or less - 16 Gauge 2 Conductor CL2/CL3
50' - 80' - 14 Gauge 2 Conductor CL2/CL3
80'-120' - 12 Gauge 2 Conductor CL2/CL3
120'-200' - 10 Gauge 2 Conductor CL2/CL3
Amplifier speaker output terminals are typically
color coded with black for negative (-) and red
for positive (+). Similarly, the M-CS have
speaker wire terminals with a black and red
color coding. When connecting speaker wire,
ensure that the positive terminal on the amplifier
is connected to the positive terminal on the M-
CS. And similarly, the negative terminal on the
amplifier should be connected to the negative
terminal on the M-CS. Speaker wires typically
use at least one of several possible methods to
help maintain correct polarity, including color
coded insulation or conductor strands, or
printing of text and symbols along one side of
the wire insulation.
Removing the Grill
The M-CS has 6 mounting tabs on the back that
rotate. While looking at the back of the speaker,
rotate the tabs fully counter clockwise so that
they stick out away from the speaker frame.
Slide each tab towards the front of the speaker
and when the tab screw comes in contact with
the grill, push gently so that the grill comes away
from the speaker.
The grill is held in place by contact pressure.
Take care when removing and reinstalling the
grill to not distort it due to excessive force.
Mounting the Speaker
While looking at the back of the M-CS, rotate the
tabs fully clockwise so that they are inside the
speaker frame (See Figure 2). If a tab does not
stay rotated, tighten its screw until it stays
rotated – do not over tighten.
Figure 2
Place the speaker into the wall cutout. One at a
time, loosen each of the six screws until the tabs
can turn freely. Next tighten each screw
clockwise until the tabs press firmly against the
inner wall surface. The speaker need only be
properly aligned and held securely to the wall –
do not over tighten to break the tabs or damage
the wall.
