PAINTING YOUR MTX IN-WALL SPEAKERS
MTX In-Wall Speakers are designed to accept all types of interior and exterior paints. Spray or roller
application should provide excellent results. A paint shield is included with all MTX In-Wall Speakers
to protect the speakers during the painting process. When paintng the grilles, simply remove the cloth
backing material before painting by pulling the material gently away from the grille. After the paint is dry,
reinsert the cloth backing material behind the grille mesh.
LOUDSPEAKER PLACEMENT
MTX In-Wall Speakers are designed to work within any interior decorating scheme. They can be installed
in virtually any location where flush mounting is possible. To maximize their sound performance however
certain guidelines should be followed. For the best stereo reproduction the two loudspeakers should be
placed an equal distance from your listening position and separated so that the speakers and the listener
form an equilateral triangle, with all sides of the triangle being the same length.
Listener
Diagram 1
For best stereo imaging, we recommend that the units be placed so that the tweeters are as close as
possible to the ear level of a seated listener. Also, the speakers should be placed so that the offset
tweeters are nearer to the inside edge of the speakers. The left and right speakers should have the
tweeter nearer to the center of the room. See Diagram 1.

INSTALLATION PREPARATION-NEW CONSTRUCTION
When installing the H615W into a newly built wall, please follow these instructions carefully.
1) Determine placement
Determine the location in the wall the speakers will be placed, using the recommendations in the
"Loudspeaker Placement" section.
2) Mount a Rough-In Kit
For best results, mount a RIK6W Rough-In Kit form Mitek Corp. (available at your MTX dealer). Follow
the instructions included with the kit.
3) The location is ready for dry wall
The RIK6W bracket provides a stable opening around which the drywall installer can cut out an opening,
providing a perfect location for the installation of the H615W.
INSTALLATION
STEP 1
Using a stud finder (available at low cost at most hardware stores) or other accurate method, locate
center point between two studs and mark. Using template provided, trace hole pattern on surface of
wall. Placing a bubble level on either the horizontal or vertical guidelines of template will assist you in
leveling the hole pattern.
STEP 2
Using a sabre saw, keyhole saw or very sharp utility knife, cut hole in wall, following traced pattern.
STEP 3
Run loudspeaker wires to sound source location. There are several methods you can use to accomplish
wiring, depending on the construction characteristics of the room or house. You can add a professional
touch to your installation by using a speaker terminal plate at the source location. Leave sufficient amount
of wire at speaker location (8 to 10 inches) to complete connection.
