IWCB Series In-Wall Closed Box Speakers
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 ½ inch (13 mm) 
away from any stud or obstruc-
tion, as the rotating clamps will 
not operate properly if you don’t. 
The speaker enclosure (the black 
box with the drivers mounted in 
it) 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. After painting 
the grille, use air pressure to “blow 
out” any grille holes that are filled 
in with paint.
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).
Installing the Speaker Enclosure into the Frame
Once the frame is mounted in the wall, the speaker enclosure simply fits 
into the frame. Note that there is a foam anti-vibration pad affixed to the 
rear panel of the enclosure. This pad will eliminate any slight vibrations 
that occur if the back of the speaker enclosure contacts the wallboard in 
the wall cavity. Due to the usual slight dimensional variances in home 
construction, the IWCB either may or may not contact the wall surface 
behind it.
Use the included screws to attach the enclosure to the mounting frame, 
but
be very careful not to overtighten the screws.
