Cavity installation with backboxCV
Locate cable and position backbox
Choose speaker locations and create
apertures by following steps 01 + 02 on
page 05. Use the cut-out templates as a
guide.
Next, pull the speaker cable through the
rubber grommet in the end of each
backboxCV and ensure speaker cables are
pulled through with a manageable length
available.
Apply each BackboxCV through each
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 a vertical
position before securing it to the
plasterboard.
A 75mm/3” cavity depth is required to fit a
BackboxCV. If a fire rating is required, fit
an Amina Firehood 200/345 first before
fitting the BackboxCV200/ 345
Fix backbox
Using a minimum of 8 drywall screws (4 at
each end) fix each backboxCV by screwing
through the plasterboard and self tapping
into the flat end cheek areas at each
end of the backboxCV. 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.

It is recommended to add sound absorbing
mineral wool or natural fibre inside the
surrounding cavities to further reduce sound
transmission to adjoining spaces.
