IWTS-28 SUB In-Wall Subwoofer
After determining the best location for the speaker as outlined above, use
the template included with the GFR-626 to cut the proper size hole.
WARNING: EXERCISE
extreme care before making any wall cuts to
ensure that you will not cut through any wires, pipes, or other items
that may be in the wall. You may sometimes, but not always, be able
to determine the approximate location of wires and pipes by looking
at the locations of nearby outlets and plumbing. But their location or
absence is never an assurance that there is not something within the
wall cavity.
Installing the Mounting Frame
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 1½ inch (38mm)
away from any stud or obstruc-
tion, as the rotating clamps will
not operate properly if you don’t.
The speaker baffle is designed
to mount into the white frame,
after the frame is mounted into
the wall.
Insert the frame into the cutout and using a level or square carefully align
it so it is level. Tighten the mounting 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 bezel
to conform to the wallboard, and the frame not to rattle from the speaker’s
vibration, but be very careful not to overtighten the screws.

Painting the Speaker Assembly
The white 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. Be sure to
remove the scrim cloth before
painting the grille. After painting
the grille, use air pressure to “blow
out” any grille holes that are filled
in with paint. Then re-apply the
scrim cloth.
Speaker Connection and Assembly
Strip about ½" (13 mm) of insulation from the connecting wires. Connect
them to the appropriate push terminal, being careful to observe polarity
(positive to the red terminal, negative to the black terminal).
