Retro-Fit
Retro-fi t installations are more diffi cult to complete than pre-
construction because walls and ceilings are intact. Typically wires
must be fi shed into position through walls, fl oors and ceilings. Holes
must be cut and speakers mounted directly in the ceiling with no
rough-in brackets. Before cutting holes in any existing wall or
ceiling surface, probe the cavity behind each speaker’s installa-
tion location for obstructions!
Cutting Speaker Openings in Walls - No Rough-in Brackets
1. Use a stud fi nder to locate the studs around the intended
speaker location.
Note: A stud-fi nding device may not detect pipes, wiring, or other
obstructions located behind the drywall.
2. Use the inside portion of the speaker cutout template to confi rm
speaker placement.
3. Remove templates and drill or carefully punch a pilot hole in the
wall. A bent piece of wire or a coat hanger may be use to probe
the stud bay for obstructions. If you experience resistance of any
kind–– STOP! If any obstructions are detected, patch the pilot
hole and try again in another location.
4. Once it has been determined that the cavity is free from obstruc
tions, position the cutout template and use a pencil to lightly
trace the perimeter of the template.
5. Cut the opening using a keyhole saw, drywall router, or razor
knife.
