PAINTING YOUR MTX IN-CEILING SPEAKERS
MTX In-Ceiling 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-Ceiling Speakers to
protect the speakers during the painting process. Simply remove the grilles before painting the speakers
and replace with the paint shield.
LOUDSPEAKER PLACEMENT
MTX In-Ceiling 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 angle between
them, at the listening position, is between 40 and 60 degrees.

INSTALLATION PREPARATION- NEW CONSTRUCTION
When installing the H515C or H615C into a newly built ceiling, please follow these instructions carefully.
1) Determine placement
Determine the location in the ceiling the speakers will be placed, using the recommendations in the
"Loudspeaker Placement" section.
2) Mount a Rough-In Kit
For best results, mount a RIK5C Rough-In Kit for H515C or RIK6C for H615C from Mitek Corp.(available
at your MTX dealer). Follow the instructions included with the kit.
3) The location is ready for drywall
The RIK5C or RIK6C bracket provides a stable opening around which the drywall installer can cut out an
opening, providing a perfect location for the installation of the H515C or H615C.
INSTALLATION
STEP 1
Using a stud finder (available at low cost at most hardware stores) or other accurate method, locate center point between two joists and mark. Using template provided, trace hole pattern on surface of ceiling
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.
STEP 4
Attach loudspeaker wires to speaker terminals, observing correct polarity, and position speaker frame up
into cutout. Be careful not to pinch wires in the process.
