Create aperture in brickwork/ concrete
Using the combination of an angle grinder
and a jackhammer drill, create a cavity of
460mm x 355mm (18
1/2
” x 14”) within the
brickwork. (460mm x 210mm for the HF
panel)
Before installing the backbox you will need
to know the thickness of render that will
be applied to the wall/ceiling prior to the
finish plaster skim.
Subtract that thickness from 50mm (2”) to
calculate the minimum cavity depth you
will need to create.
Create channel for cable
Using an angle grinder or hammer and
chisel, create a channel that runs into this
cavity, this will allow the speaker cable to
be pulled into a suitable position within the
cavity.
We recommend the cable is run in a
suitable conduit to protect it.
Leave enough cable slack to allow
connection to the speaker when it is held
away from the cavity.
