Solid Surface Ceiling (Sheetrock)
In a sheetrock ceiling installation it is necessary to install the preconstruction ring and backbox assembly
before the installation of the sheetrock. Referring to Figure 3 mount the backbox to the speaker mounting
ring and attach the assembly to the ceiling joists using the appropriate hardware. Cut a 12 1/8” diameter
hole in the in the sheetrock to provide clearance for the speaker mounting ring and backbox assembly.
Before continuing speaker installation using a small screwdriver set Volume Control to 2/3
rotation.
Place the large rubber O-ring on the back of the speaker assembly and using the four screws
equipped with washers and O-rings mount the speaker assembly to the speaker ring/backbox assembly.
Do not over-tighten the speaker mounting screws. Hand-tighten only. For a proper seal the large O-ring
should compress slightly. It is not necessary for the edge of the metal grille to touch the ceiling for a
proper seal.
Refer to Figure 3.
