Install backbox
Make a small hole in one of the rubber
grommets and pull the speaker cable
through it and into the backboxSW. There
are four slots in the base of the backboxSW
and using suitable screws (not supplied),
fix the backboxSW to the brickwork within
the cavity. Ensure the front edge of the
backboxSW aligns flush with the front face
of the surface which will have the final 2mm
skim coat of plaster applied.
We recommend shims are fitted behind the
backboxSW to achieve a level solid fixing. It
is recommended to add expanding foam
around the sides and rear to prevent
resonance and also to add mineral wool
(max 1”) to the inside of the BackboxSW.
NB: If there is a layer of render to be applied
or already applied to the brickwork, be sure
to align the front edge of the backboxSW
to the front edge of the render (As shown in
the lower section of the image)
Connect speaker
Connect the speaker cable to the speaker
using a high quality crimping tool.
Your Evolution Series speaker is fitted with
blue butt splice crimp connectors which are
suitable for speaker cable thicknesses of
1.5mm
2
- 2.5mm
2
(16 - 14AWG). This type of
connector ensures a permanent “shake-
proof” connection is created inside your
wall cavity.
