Installation in the Ceiling
Dry-Wall Ceiling Installation
There are three basic ways to install a Community C SERIES loudspeaker
assembly into a drywall ceiling (a.k.a. sheet rock or gypsum board). Some are for
new construction, others for retrofit to existing construction. We recommend
some methods over others and of course the choice is yours.
1. The preferred method for new installations is to use the optional New
Construction Bracket, pre-installing it directly to the supporting beams
before the sheet rock is applied. Multiple small holes on wings to either side
of the main cutout hole allow the installer to use screws or nails to secure
the ring to the straddling beams. See the following subsection for step-by-
step details and variations.
2. An alternative method for new installations – where the ceiling has already
been completed – is to use the Tile Bridge Support Rails. While there are no
truss members across which the rails fit, nonetheless they will distribute
the weight of the loudspeaker assembly across a greater area and will thus
avoid sagging or having the mounting clamps cut into the ceiling that might
otherwise occur over time. You can cut the hole using the provided template
or using a New Construction Bracket as a cutting guide, even though this
bracket won't be used for the actual installation. It's then easy to pass the
Tile Bridge Support Rails through the cutout, then the Spacers, and align the
loudspeaker mounting clamps so they rest top of the rails. Refer to Figures
9 and 10.
3. Retrofit an entire Community C SERIES Loudspeaker Assembly into an
existing oversized ceiling cutout using a corresponding C SERIES CATR Can
Adapter Trim Ring.
Pre-Installation in a New Drywall Ceiling
Optional New Construction Brackets are available for installing loudspeakers
in new construction before drywall or plaster is put in place. Refer to the chart
on page 13 for sizes and model numbers.
The New Construction Brackets support the loudspeakers in plaster/dry
wall ceilings. Multiple holes in the bracket's two "ears" permit convenient
attachment to nearby ceiling beams. The drywall typically is cut with a router-
type tool, in which case the bracket central hole will serve as a cutout guide for
the router bit.
Inserting the Loudspeaker Assembly into the Drywall Ceiling
1. Bring the wiring from the ceiling to the top of the can and attach it to the
terminal block (see the Wiring Section and Figure 2). Secure the wiring with the
top plate/strain relief clamp.
2. Before sliding the back can into the ceiling hole, slightly bend each
Drop-Stop™ installation assistant tab outward from the back can 1/2 inch
(12mm). Slide the loudspeaker into the hole. When pressing the unit fully into
place, the two Drop-Stop™ tabs will spread atop the tile support bridge rails,
and you may hear them "snap" into position; you can now continue without
having to hold the back can in place. The illustration in Figure 7 shows how
the Drop-Stop™ tabs work, and is equally applicable with New Construction
Bracket installations in drywall ceiling
3. Locate the two Phillips-head can clamp actuators around the perimeter of the front flange, and using a #2 Phillips
screwdriver twist each actuator clockwise until you feel tension as the clamps securely lock the loudspeaker into
the ceiling (Figures 8 and 9 on page 10). These clamps open fully to 2.35" (59.6 mm), but we allow at least 0.60"
(15.2mm) to grab the Tile Bridge Support Rail atop the ceiling. Loudspeakers leave the Community factory with these
clamps fully open so that approximately 1.75
