UNPACKING YOUR SPEAKERS
After carefully unpacking your speakers, the carton and the
packing material should be saved for possible use later. If
any speaker appears to be damaged, do not attempt to
repair or to connect the unit to the amplifier. Repack the
speaker and notify your distributor or M&S Systems for
replacement or repair.
SPEAKER LOCATION
Careful consideration must be given to the speaker location
to realize the full frequency range. Ceiling speakers should
be spaced 6 to 8 feet (6 feet for 8-foot ceilings and 8 feet
for 10-foot ceilings and above) apart but no closer than 2
feet to any adjacent wall. Avoid placing speakers in air re-
turn cavities. Some type of protection will be required for
the back of the speaker if blown insulation is used. The fol-
lowing is a partial list of ways to protect the speaker:
•
•
Use an RE-16 speaker cover (sold separately).
Use a piece of wood that will cover at least 3’ on either
side of the speaker opening. The ends may be partially
closed to keep the blown insulation from reaching the
speaker, however, a minimum gap of 2” at each end is
better than a sealed box.
•
•
Use a piece of bat insulation at least 3” thick over
the back of the speaker. This insulation should not
have a backing or if it does, the backing must be in-
stalled facing away from the speaker.
Use a fine mesh to cover the back of the speaker to
protect against bulk type insulation materials. This
will not work with insulation containing fine pow-
ders.
Do not install speakers in stud cavities containing
120/240V appliances, within 18 inches of dimmer light
fixtures, security wiring and other control wiring.
SPEAKER INSTALLATION FOR
NEW CONSTRUCTION
Step 1. After you have determine the speaker locations
using the guidelines above, secure a 16 gauge 2 conductor
cable, such as the M&S Systems MS16X, (DO NOT USE
STAPLES) for attachment to the speakers after the dry
wall has been installed. NOTE: On the model S40C2,
you will need to run 2-2 conductor cables to the speaker
location for connecting the left and right signals to pro-
duce a monaural sound. Leave at least 18 inches addi-
tional cable for the connection during final speaker instal-
lation. Run the other end of the speaker cables to the
speaker volume control location and secure in a single
gang box along with a 4 conductor 16 gauge cable, such
as the M&S Systems MS164X, that will connect to the
amplifier. NOTE: Make a drawing of each speaker
location. This will assist you in locating the wires that
have been covered after the sheet rock has been
installed.

Step 2. To begin installation of the speakers, first locate
the area where the wires are installed. At each location,
cut a hole to the dimensions shown for the model being
installed (Mounting Dimensions) in the tables found on
pages 1-3. The cutout should be centered in the stud
space opening. Prepare the speaker wiring by stripping off
approximately 3 inches of the outer jacket (care should
be taken so the insulation on the wires inside the jacket
are not damaged) also strip approximately 3/8 inch off the
ends of the two inside conductors. Twist the ends of the
stranded cable so the wires are tight.
Step 3. You are now ready to install the speaker. Re-
move the front grille from the speaker. (Be careful not
to touch the speaker cones in order to prevent any dam-
age). Attach the speaker cable to the speaker by pressing
down on the red (+) or black (-) tabs and inserting the
red wire in the red terminal and the black wire in the
black terminal. See Figure 1. Make sure that none of the
strands from the black and red wires are touching each
other. This can create a short circuit that can damage
your electronics. Index the mounting tabs to make sure
that all tabs will clear the opening. Insert the speaker in
the wall and tighten the tabs with the screws on the front
of the grille. DO NOT OVERTIGHTEN THE SCREWS,
the screws should only be tight enough to secure the
speaker.
Step 4. After the speaker is mounted, adjustments to
the swivel tweeter (small speaker) can be made by either
directing the sound visually or by using a musical source
to determine the best sound coverage for the listening
area. To position the tweeter, press at the outside edge
of the tweeter cone area (DO NOT PRESS ON THE
CONE DIRECTLY).
Step 5. Divide each adhesive bead strip in half.
(Adhesive bead strips are in the clear self-closing bag).
Place strips on the edge of the grill as shown in Figure
2. Reinstall the grill on the speaker.
Step 6. Follow the instructions included with the vol-
ume control and amplifier to complete the installation.

SPEAKER INSTALLATION FOR EXISTING
CONSTRUCTION
For existing construction, use the same guidelines for
new construction with the following precautions. It is
very important to determine what is behind the wall
space that you will open when installing the speakers.
Check for standard stud spacing (16” on center pre-
ferred) so you will not need to cut studs and check the
wiring path to the volume control and amplifier. Avoid
120V wiring and air return duct and pipe. Proper
speaker spacing is also critical to a good system.

The only difference between new and existing
construction is the order in which the process is done
(steps 1, 2 and 3). In existing construction the speaker
hole is cut, the wire is run to the volume control box,
and the speaker is connected to the wiring and installed
in the wall. You are ready to complete the process using
steps 4, 5, and 6 for new construction.
