Drywall Installation
1. The installation of drywall around the back can location is best done using
a single large sheet with the vertical center line centered over the back can
vertical centerline (Fig. 6). Alternatively, the cover can be left on, and the
drywall installed in
four sections around the cover.
2. If you want to cut the drywall aperture before installation, use the back can
cover as a guide. Step 4 below describes cutting after the installation. Use the
method you prefer.
3. Use adhesive on the wall studs and the front face of the back can, and install
the drywall using drywall screws approximately 8 to 10 inches apart. This will
help prevent wall rattling and drywall movement and noises during operation.
If the back can is being installed on an interior wall, then adhesive and extra
screws may also be added to the drywall used in the room behind the back can.
CAUTION: Make sure that no drywall screws go into the wooden case of the
back can at any point.
4. After the drywall installation, carefully cut out the hole in the drywall with
a suitable handtool, using the aperture in the back can as a guide (Fig. 7).
Be careful not to cut inside the back can aperture, or cut the speaker wires.
Make sure the drywall aperture is no larger than the aperture of the back can.
Remove any dust or debris from within the back can.
5. The cover may be reinstalled until it is time for the loudspeaker installation.
PCI 7DC IW Installation
With the PCI 7DC IW back can wired and installed and the drywall cut as shown
in the previous instructions, the PCI 7DC IW loudspeaker assembly can be fitted
into the back can.
Procedure
1. With the help of an assistant, lift the PCI 7DC IW loudspeaker assembly close to
the drywall aperture, and securely attach the four-pin wiring connector into
the corresponding connector inside the back can (Fig. 1).
2. Install the loudspeaker assembly into the back can, by  rst pressing in the four
screws as far as they will go, and then hand-tightening (Fig. 2). Make sure that
you do not trap the speaker wiring, or your  ngers during the installation.
CAUTION: Do not over tighten the screws - this is unnecessary to achieve a
strong acoustic seal to the back can or wall, and risks damage .
Painting
1. A paint mask is supplied to protect the loudspeaker ba e and drivers from
paint, dust, and debris. It allows you to paint and  nish the wall after the
installation of the loudspeaker assembly into the back can.
2. Press the paint mask into the front of the frame, where it will be kept in
place by magnets. This mask is left in place while the wall and frame surround
are painted (Fig.3).
3. It is strongly recommended that the metal perforated grille is sprayed
separately, as this will avoid clogging of the holes. If painting with a brush is
the only option, then several thin coats of paint will provide a superior  nish to
that achieved by one applied too thickly.
