Locate cable and position backbox
Choose speaker location and create aperture
by following steps 01 + 02 on page 05.
(remember to keep the 455mm x 350mm
(18” x 14”) cavity)
Next, pull the speaker cable through the
rubber grommet in the top side of the
backbox and ensure speaker cables are
pulled through with a manageable length
available.
Apply the Backbox through the hole at an
angle until the end cheeks rest against the
back side of the plasterboard.
Use the fold out tabs at either end of the
backbox to help support it in position before
securing it to the plasterboard.
A 75mm/3" cavity depth is required to fit a
Backbox FS or Backbox FSS.

Fix backbox
Using a minimum of 8 drywall screws (4 at
each end) fix the backbox by screwing
through the plasterboard and self tapping
into the flat end cheek areas at each end of
the backbox. When positioned correctly, the
backbox's speaker mounting lip with soft
foam surface should be visible along all four
sides of the aperture.
Connect the speaker by following step 05 on
page 07.
