5. Using a Pre-mount Kit
Custom install pre-mount kits enable the locations of
in-ceiling and in-wall speakers to be defined before
the sheetrock (plasterboard) is fitted to the studs
(joists). Routing and cutting of speaker cable is also
made easier using pre-mount kits. A pre-mount kit
(PMK) comprises a plastic moulding that defines
the aperture size of the specific speaker model, two
perforated metal straps and four plastic clips.
To use a PMK, first attach one strap to each side
of the moulding using the plastic clips. The PMK
assembly can now be attached to the studwork
by nailing the metal straps to the studs so that
the plastic moulding is located at the appropriate
position.
When the sheetrock (plasterboard) is subsequently
fitted (marked on the outside to denote the position
of the pre-mount kit) the PMK plastic moulding
serves as an internal cut guide that significantly
eases cutting the speaker aperture.
Diagrams 6-9 illustrate PMK installation.
