„ „ Installation: Existing Construction
(retrofitting finished walls)
Warning: Exercise caution when drilling into existing walls. Do not drill
through existing wires, pipes, conduits, heating or air conditioning ducts. If
you feel resistance while drilling, stop immediately.
1. Using a studfinder or the “knocking” method, locate the wall studs in the wall
area where you wish to mount the speaker. The speaker will be mounted
between adjacent studs, no closer than two inches from either stud (fig.7).
2. Determine that there are no obstructions behind the desired cutout area. This
may be accomplished by drilling a hole in the center of the cutout area and using
an “L”-shaped piece of metal (like a coat hanger) to “feel around” behind the wall.
If you discover an obstruction, fill the hole with patching compound and try anoth-
er location.
3. If there are no obstructions found behind the wall, use the supplied cutout tem-
plate and a pencil to draw a 12-1/8”H x 8”W outline of the area to be cut out. Use
a level to ensure that the cutout is precisely positioned. Begin by drilling the four
corners with a 1/4” bit (fig.7). Then cut out the wall section with a utility knife or
keyhole saw, following the lines traced around the mounting template. If the wall
is painted or wallpapered, use the keyhole saw.
4. If the wall is constructed of lath and plaster, outline the penciled marks with
masking tape, drill the four corners with a
1/4” drill bit, and use a utility knife to cut through the plaster down to the lath. Use
a saber saw with a metal cutting blade or a pair of tin snips to gently cut through
the lath, being careful not to vibrate plaster off the wall.
5. Insert the SuperOne Ci mounting bracket diagonally through the cutout in the
wall, then pull forward into position. If the cutout was cut correctly according to
the cutout template, the bracket should fit snugly into place. The plastic tabs on
all sides of the bracket will rest flatly against the back side of the wall (fig.8).
6. While holding the bracket flatly against the rear side of the wall with one hand,
attach the bezel to the bracket with six 4 x 16mm flathead screws that line up with
the six raised bosses on the bracket (fig.9). If the bezel is not installed in the prop-
er orientation, all six screw holes will not line up. Tighten screws snugly, making
sure not to over-tighten, as this may compromise the fit of the bezel. The use of
power screwdrivers is not recommended. The absorptive strips on the back of the
bezel’s outer frame prevent unwanted vibrations against the drywall, and will com-
press slightly to allow the frame to rest flush against the wall on all four sides.
When installed correctly, the bracket and bezel “sandwich” the drywall.
7. If the SuperOne Ci bezel frame and grille are to be painted in the wall, paint
