Locate joist work
When you have chosen your speaker
locations, before cutting a hole in the
plasterboard it is important that you locate
the position of the wall studs. Ensure the
spacing between them is at least 350mm
(133/4”) for a portrait orientated speaker.
01
Create 455 x 350mm aperture
Using a sharp knife or pad saw, cut an
aperture with dimensions 455mm x 350mm
(18” x 14”) in your plasterboard wall or ceiling.
Ensure aperture is created between
supporting joists or stud work.
We strongly advise that joists are not cut to
make space for the backbox. Any activity of
this sort may well influence the structural
integrity of your property.
Important: Double check the size of the
aperture is 455mm x 350mm (18” x 14”) as
this is important further on into the
installation process.
