Diameter Hole Opening

Figure 1. CM4PR loudspeaker installation dimensions

These require a 4-5/8” (11.75 cm) diameter hole opening with a minimum of 3-5/16” (8.42 cm) depth when measured from the interior face of the drywall, plus at least 5” (11.75 cm) clearance to one side of the loudspeaker opening for the Rear Wave Control enclosure. To the sides of the hole you will need 1” for the mounting tabs to clamp the speaker to the drywall.

When running loudspeaker wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3 rating) to protect the wire and for fi re prevention. In some municipalities, conduit is required. For a trouble-free installation, low voltage wire such as loudspeaker wire must be in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional audio/video installer, building contractor, or the local building and inspection department.
