Installation
• If this is new construction, we strongly recommend using
drywall. It's heavier and more expensive than ½" material, but it's far,
far superior in terms of acoustic/mechanical integrity and rigidity. We
also strongly recommend that the drywall be screwed to the studs every
6 inches or so, instead of the more common practice of nailing it every
12-18". Use screws for at least a full stud bay on either side of where the
IW-28 SUB will be mounted.

Mounting Template
Mounting Template
Mount frame as shown,
with IR knockout in
upper-right corner.
Remove scrim before
painting grille.
After determining the best location for the speaker as outlined earlier, use a
level with the template to mark out the hole. Then using care, cut the proper
size hole. (11 1/8" x 20 3/8")
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 Speaker Assembly

Insert the speaker assembly into the cutout and using a level carefully align
the speaker so it is level. Loosen the mounting screws ½ turn, then tighten
them, which will cause the attached clamps to unlock, 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 wall surface, and the frame not to rattle from the speaker's
vibration, but be very careful not to over tighten the screws.
Painting the Speaker Assembly
holes that are filled in with paint. When the grille is dry, re-apply the scrim
cloth. You may need to use a light coat of low tack spray adhesive to hold
the scrim in place.
IW-28 SUB In-Wall Subwoofer
The clamping mecha-
nism accommodates wall
material from ½ to 1½
inches (13 to 38 mm) in
thickness. There must be
a minimum depth behind
the wall face of 3-5⁄8" (92
mm). As noted earlier,
be sure to keep the edges
of the cutout at least 1½
inches (38mm) away from
any stud or obstruction,
as the rotating clamps will
not operate properly if you
don't. There are holes in the
baffle providing access to
the rotating clamp screws
(See fig left). There is no
need to disassemble the
speaker for installation.
The white plastic frame and 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. You will need to remove
the baffle from the frame before
painting. 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. Start at one corner and gen-
tly peel the scrim from the grill.
After painting the grille, use air
pressure to "blow out" any grille
