Installation
Retrofit / pre-skimmed solid wall cutaway
(Feathered plaster finish)
Finishing
This method positions the speaker for
a large area (approx. 1m
2
(39”)) to be
skimmed over it. This 2mm (
5
/
64
”) thick
skim is then feathered outward at the
edges and blended into the existing wall/
ceiling finish.

Cavity depth
The cutaway drawing on the right shows
the alignment of the BackboxSW in the
cavity.
• Temporarily remove the denim pad.
• Use shims between the back of the
BackboxSW and the inside of the
cavity to align the front edge of the
plastic trim with the front face of the
finished wall.
• Use expanding foam to fill any
cavities behind and to the sides of the
BackboxSW.
• Replace the denim pad.
• When the BackboxSW is fixed
securely into the cavity, remove the
plastic trim ready for installation of
the loudspeaker and then application
of the final skim coat.
