MECHANICAL INSTALLATION 110SR
NEW / EXISTING CONSTRUCTION INSTALLATION PROCEDURES:
6) Leave some excess wire hanging through the opening in the pre-installation ring so the drywall contractors can cut
a hole and drop the wires through. You may also want to consult with them on cutting the opening for the sub as
they will likely have power tools. (Fig. 11) necessary to quickly and accurately cut out the opening (Fig. 5).
7) If you are inexperienced, but plan on doing this yourself, the job can be made easier by proceeding in two steps.
A) “Hog” out the major inside portion of the material (Fig. 5).
B) Carefully cut out the recess for attaching the subwoofer (Fig. 6).
8) A word about the Rotozip™ tool for cutting holes in wallboard: using the correct bit and accurately setting the cutting
depth will greatly reduce any errors caused by the tool “getting away” or cutting into the pre-installation ring. Use
only a Guidepoint™ bit (Fig. 11); it will follow the inside perimeter of the pre-installation ring. For the first cut, set
the depth to the thickness of the wallboard plus 5/8” (the thickness of the pre-installation ring). Example: 5/8” pre-
installation ring plus 5/8” wall board equals 1 -1/4” cutting depth.
9) After the majority of the material has been removed from the center of the pre-installation ring, you can set the
cutting depth for the second step. Holding the tool up to the opening, set the depth gauge so that the Guidepoint™
bit will now follow the recessed cutaway in the pre-installation ring.
10) After cleaning the remaining debris and dust from the opening, it should look like (Fig. 6). Take note of the location
and color of the 11 “T” nuts are gold in color, to differentiate them from the remaining seven which are for securing
the 110SR in place.
11) You must align the cutout on the 110SR with the same control access cutout (indicated with red paint) on the pre-
installation ring, that will allow you to make adjustments to the system later. Orient the signal cable to the cutout
and prepare to make the AC mains connection before completing the next step.
12) Put the subwoofer into place, resting it on an angle (Fig.7) on the secondary wooden installation “ledge” on the side
of the sub; this will assist you in getting a hand free to operate the screw gun (Fig. 8). There are seven 3” Phillips-
head, 8 - 32 black machine screws for securing the 110SR to the pre-installation ring.
13) The subwoofer is normally installed in place after painting is completed to keep the sub looking new (Fig.9). Installing
the grille (Fig. 10) with the four remaining white 3” Philips-head 8-32 screws completes the 1110SR installation.
