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
BackboxSW with the (eventual) front
face of the base coat render.
• Use expanding foam to fill any
cavities behind and to the sides of the
BackboxSW.
• If base coat render is not in place,
render up to the plastic trim.
• Once the render is dry, remove the
plastic trim and replace the denim
pad ready for installation of the
loudspeaker and then application of
the final skim coat.
