Secure the speaker
Ensure the speaker cable is laid behind the
mineral wool and cannot rest against the
speaker itself.
Remove the backing paper from the 6
adhesive pads on the backbox mounting
tabs, carefully position the speaker onto the
support tabs and apply moderate pressure.
There should be an equal perimeter gap
between the backbox and the edge of
the speaker.
Use the flange head screws (supplied with
the backbox) to fix the corners of the
speaker to the four corner support tabs.
If the correct steps are taken to align the
backbox with the front face of the render, the
loudspeaker, when screwed in place, will also
sit flush with the front face of the render.
Do not adjust the screws in any way, make
sure they are tightly screwed in place and
the whole assembly is firm.
