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.
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.
