Drywall Installation
1. T he insta ll ation of drywa ll around the back can l ocation is best done using
a sing l e l arge sheet with the vertica l center l ine centered over the back can
vertica l center l ine ( F ig. 6). A l ternative l y, the cover can be l eft on, and the
drywa ll insta ll ed in four sections around the cover.
2. I f you want to cut the drywa ll aperture before insta ll ation, use the back can
cover as a guide. Step 4 be l ow describes cutting after the insta ll ation. Use the
method you prefer.
3. Use adhesive on the wa ll studs and the front face of the back can, and insta ll
the drywa ll using drywa ll screws approximate l y 8 to 10 inches apart. T his wi ll
he l p prevent wa ll ratt l ing and drywa ll movement and noises during operation.
I f the back can is being insta ll ed on an interior wa ll , then adhesive and extra
screws may a l so be added to the drywa ll used in the room behind the back can.
CAUTION: Make sure that no drywa ll screws go into the wooden case of the
back can at any point.
4. After the drywa ll insta ll ation, carefu ll y cut out the ho l e in the drywa ll with
a suitab l e handtoo l , using the aperture in the back can as a guide ( F ig. 7 ).
Be carefu l not to cut inside the back can aperture, or cut the speaker wires.
Make sure the drywa ll aperture is no l arger than the aperture of the back can.
Remove any dust or debris from within the back can.
5. T he cover may be reinsta ll ed unti l it is time for the l oudspeaker insta ll ation.
PCI 7DC IW Installation
With the PC I 7 DC I W back can wired and insta ll ed and the drywa ll cut as shown
in the previous instructions, the PC I 7 DC I W l oudspeaker assemb l y can be fitted
into the back can.
Procedure
1. With the he l p of an assistant, l ift the PC I 7 DC I W l oudspeaker assemb l y c l ose to
the drywa ll aperture, and secure l y attach the four-pin wiring connector into
the corresponding connector inside the back can ( F ig. 1).
2. I nsta ll the l oudspeaker assemb l y into the back can, by fi rst pressing in the four
screws as far as they wi ll go, and then hand-tightening ( F ig. 2). Make sure that
you do not trap the speaker wiring, or your fi ngers during the insta ll ation.
CAUTION : Do not over tighten the screws - this is unnecessary to achieve a
strong acoustic sea l to the back can or wa ll , and risks damage.
Painting
1. A paint mask is supp l ied to protect the l oudspeaker ba ffl e and drivers from
paint, dust, and debris. I t a ll ows you to paint and fi nish the wa ll after the
insta ll ation of the l oudspeaker assemb l y into the back can.
2. Press the paint mask into the front of the frame, where it wi ll be kept in
p l ace by magnets. T his mask is l eft in p l ace whi l e the wa ll and frame surround
are painted ( F ig.3).
3. I t is strong l y recommended that the meta l perforated gri ll e is sprayed
separate l y, as this wi ll avoid c l ogging of the ho l es. I f painting with a brush is
the on l y option, then severa l thin coats of paint wi ll provide a superior fi nish to
that achieved by one app l ied too thick l y.
