Installation

The loudspeaker can be installed both on the ceiling and 
on a vertical surface. It is strongly recommended that the 
mounting surface is flat (not curved).

Ensure that the mounting surface is free from 
obstructions, pipes or studs, either in front 
and behind the surface.

The cable runs and cable pipes shall be 
set according to the loudspeaker system 
configuration. The cables must be of 
adequate quality, suitable for the installation’s 
environmental conditions and with proper 
copper section to minimize power loss.

Remove the grill from the loudspeaker and keep it 
in a safe place.

Position the cutout template and mark the surface 
accordingly.
Drill a pilot hole, then cut all of the way around the 
circular outline with a cutting saw.

Pull the speaker wire out of the hole and connect 
it to the loudspeaker.

Insert the loudspeaker into the hole and tighten all 
the clamp screws with a Phillips #1 screwdriver.

Reposition the grill on the loudspeaker.
