Mount/Remove Speakers
The in-ceiling speakers include four toggle clamps and four
stabilizing spring clips that simplify the mounting process.
If grilles are mounted on the speakers, remove them
before proceeding. (Refer to “Install/Remove Grilles”,
below.)
1. Connect the speaker cable wires to the spring termi-
nals by pressing the top of the terminals down and
inserting the exposed strands into the hole. Make sure
that left and right channels are connected to the left
and right speakers, respectively, and that the
+
wires
go to the
+
(red coded) terminals, and the
–
wires go to
the
–
(black coded) terminals.
2. With the toggle clamps turned inward, insert the
speaker into the opening; the stabilizing spring clips
will help to hold the speaker in place. As you tighten
the four screws on the front of the speaker, the toggle
clamps will first rotate into clamping position (refer to
the figure to the right) and then begin holding the
speaker to the ceiling. Tighten the screws until the
speaker is secure; do not overtighten.
3. Speaker removal is accomplished by reversing the
procedures given in steps 1 and 2 above.
a. Loosen the front screws to unclamp the speaker.
Continue to loosen the screws until the toggle
clamps rotate inward.
b. When the speaker is loose, carefully reach up into
the opening and press the spring clips inward so
the speaker can be removed from the opening.
c. Disconnect the wires from the terminals.
Install/Remove Grilles
To install the grille, place it in position and carefully press
until the surface of the grille is flush with the surface of the
outer flange.
To remove the grille, insert a slim, flat-blade screwdriver
between the grille and the outer flange, and carefully pry
the grille up and out.
It may be necessary to press one or more of the mounting
screws and toggle clamps toward the front to push the
grille free of the flange.
Before finalizing the speaker locations, check to
make sure there are no fixtures, pipes, air ducts,
joists, or other possible obstructions. Use a good
quality stud finder to locate joists.
If you do not have access to the area above the
ceiling, and you are unable to verify that there are
no obstructions, carefully drill a small hole just
through the ceiling near the middle of the proposed
speaker location(s) and use one of the commer-
cially available inspection devices designed for this
purpose, or do one of the following:
● Use a piece of stiff wire, bent into an “L”
shape, with one end long enough to explore an
area equal to the size of the speaker with the
toggle clamps extended. Insert the wire into
the hole, make sure it rotates freely in a
complete circle and that there is sufficient
depth,
or
● Use a drywall saw to cut a small hole at a 45°
angle toward the inside of the hole. An angle
cut simplifies repair since the removed piece
can be reinserted to help plug the hole.
If there are no obstructions, use the supplied
template to trace outlines of the mounting holes on
the ceiling. Cut the final mounting holes at a 90°
angle to the ceiling.
Paint the Speakers/Grilles
Speaker rim and/or grille painting should be done
prior to mounting.
1. Leave the painting plug installed in the front of
the speaker.
2. Carefully remove the material on the underside
of the grille and set it aside for reinstallation. It
may be necessary to use a knife or other
sharp instrument to free an edge of the
material so it can be peeled away. Use care to
avoid cutting the material.
3. Dry brush or lightly spray the surface to be
painted. Use care to avoid clogging the holes
in the grille.

Determine Placement In Room
Speaker placement depends on the size
and primary purpose of the room.
For home theater applications, the Excite
in-ceiling speaker line is an excellent
choice for the surround and back chan-
nels.
As indicated in the figure to the right,
suggested placement is at the angles
from the 0° primary viewing/listening
angle.
For applications such as classrooms,
conference rooms, and multi-room audio
distribution installs, other considerations
in speaker placement are ceiling height,
and whether listeners are more likely to
be seated or standing.
The table below and the diagram to the
right help to show proper speaker
spacing for optimum sound coverage.
