IW-155 LCR THX Ultra2 In-Wall Thin Bezel LCR Speaker
Installing the Speaker
The clamping mechanism allows
the wall material to range from
½ to 1½ inches (13 to 38 mm) in
thickness. There must be a mini-
mum depth behind the wall face
of 3
5
⁄
8
” (92 mm). As noted above,
be sure to keep the edges of the
cutout at least ½ inch (13 mm)
away from any stud or obstruc-
tion, as the rotating clamps will
not operate properly if you don’t.
There are holes in the baffle
to allow access to the rotating
clamp screws (see adjacent illus-
tration.) There is no need to
disassemble the speaker before
installation. The rotating clamps
crews have a Phillips #2 head.
Insert the speaker assembly into
the cutout and using a level or
square carefully align it so it is
level. Tighten the rotating clamp
screws, which will cause the
attached clamps to rotate and
position themselves properly
behind the wall.
Continue to tighten until the frame is snug in the wall. You want the
frame to conform to the wallboard, and not rattle from the speaker’s
vibration,
but be very careful
not to overtighten the screws.
Painting the Speaker
Assembly
The plastic frame and the metal
grille may be left as is, or painted
to match your décor. You can
paint the frame before or after
it is installed in the wall. Spray
painting (using slightly thinned
paint) is the best method to use
for painting the grille.
Before painting the grille, carefully peel off
the cloth scrim from inside the grille.
After painting the grille, use air
pressure to “blow out” any grille holes that are filled in with paint. Once
the paint is dry, re-apply the scrim to the inside of the grille.
Speaker Connection and Assembly
Strip about ½” (13 mm) of insulation from the connecting wires. Con-
nect them to the appropriate push terminal, being careful to observe
polarity (positive to the red terminal, negative to the black terminal).
