 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.

Mounting Template

Mount frame as shown, 

with IR knockout in 
upper-right corner. 

Remove scrim before 

painting grille.

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).
