Installing the Drywall
1. The installation of drywall around the back can location is best done
using a single large sheet centered around the back can location (Fig. 4).
Use adhesive on the front face of the back can, and on the ceiling joists, and
install the drywall using drywall screws approximately 8 to 10 inches apart.
This will help prevent ceiling rattling and drywall movement and noises during
operation. CAUTION: Make sure that no drywall screws go into the wooden
case of the back can at any point.
2. After drywall installation, carefully cut out the hole in the drywall with a
suitable handtool, using the rectangular aperture of the back can as a guide
(Fig. 5). Be careful not to cut the speaker wires or any of the back can wood.
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.
3. Install the back can cover using the four screws. This cover can be left in place
during painting and finishing of the ceiling, and then removed when the
loudspeaker assembly is ready for installation. (Painting can also be done when
the loudspeaker assembly is position, as it is supplied with a painting mask.)

Installation into the Back Can
With the back can installed and wired as shown in the previous pages, the
loudspeaker assembly can now be installed into the ceiling and back can.
1. Remove the back can cover if it is in place.
2. With the help of an assistant, hold the speaker assembly up close to the
back can aperture.
3. The loudspeaker has four wires and a connector attached. Securely join this to
the matching connector in the center of the back can aperture.
4. The speaker assembly can now be connected to the back can using four screws
as shown. Take care not to trap or pinch the speaker wiring, or your fingers or
tie (Fig. 6).
Painting
1. A paint mask is supplied to protect the loudspeaker from paint, dust, and
debris. It allows you to paint and finish the ceiling after the installation of the
loudspeaker into the ceiling.
2. Press the paint mask into the loudspeaker assembly, and it will be kept in
place by magnets. This is left in place while the ceiling and frame surround is
painted
3. It is strongly recommended that the metal perforated grille is sprayed, 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 finish to that achieved
by one applied too thickly.
