Installation
Mounting the BackboxSW
• Make a small hole in the rubber
grommet at the cable entry point and
pull the speaker cable through it and
into the BackboxSW.
• There are four keyhole slots in the
back of the BackboxSW. Using
suitable screws and wall plugs (not
supplied), fix the BackboxSW to the
brickwork/concrete within the cavity.
• Check that the BackboxSW is fitted
securely into the cavity.
• To complete the installation it is
recommended to add expanding
foam behind and around the sides of
the BackboxSW to prevent resonance.
• Render or make good up to the
plastic trim. Allow to dry.
• Remove the plastic trim immediately
prior to installing the speaker and
apply the finishing plaster skim coat.
