Figure 12 - Bowers & Wilkins ISW-3 Mode D'emploi

Use the cut-out template (e) to mark the aperture on
the drywall panel. The six protrusions correspond
to the outer dimensions of the louvre fascia and are
provided to indicate necessary clearance. Do not
mark round these protrusions, but rather along the
dotted lines that cross them (Figure 12).
At this point, you may apply flexible mastic to the
face of the subwoofer cabinet to prevent rattles
against the ceiling panel.
Fit the frywall panels to the ceiling joists (Figure 13)
and apply the final skim coat.
Paint the ceiling at this stage and, if desired, paint
the louvre fascia moulding (b) to match. The part will
take all normal wall paints.
Attach the louvre (c) to the front of the opening
and secure it to the louvre frame using the two M3
machine screws (i) through the two bars. Do not
over-tighten. There should be slight bending tension
in the two louvre bars, but the surround should not
be distorted or the fascia will not fit correctly.
Clip the fascia (b) to the louvre (c) (Figure 14).
