C. Retrofit a Distributed Series Loud-
speaker (driver/face plate without back
can) into an existing back can using a
corresponding Distributed Series Face
Adapter Ring .
D. Retrofit an entire Community Dis-
tributed Series Loudspeaker Assembly
(including back can) into an existing back
can using a corresponding Distributed
Series Can Adapter Ring .
Note : If you are retrofitting a new loudspeak-
er alone, without back can, into an existing
low-profile back can for a 4.5

competitor’s
model (minimum 3.5
"
/ 89 mm deep), you can
use the D4-FO loudspeaker alone, but if you
wish to drop an entire Loudspeaker Assembly
into an existing 4.5
"
can, use the D4LP (with
Can Adapter/Trim Ring). While the latter
includes a shallow back can, both the D4 and
D4LP use the same D4-FO loudspeaker which
has a shallow depth.
Note : We do not offer a Face Adapter Ring for
our larger model loudspeakers.
Details for 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. See Figure 29, and refer to the chart
on page 11 for sizes and model numbers.

Dry-Wall Ceiling Installation
There are four basic ways to install a Com-
munity Distributed 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.
A. The preferred method for new
installations is to use the optional New
Construction Bracket, pre-installing it di-
rectly 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.
B. An alternative method for new in-
stallations – where the ceiling has already
been completed – is to use the C-Ring Sup-
port Plate along with the Tile Bridge Sup-
port Rails. While there are in fact not going
to be truss members across which the rails
fit, nonetheless they will distribute the
weight of the loudspeaker assembly across
a greater area than the C-Ring Adapter
alone and will thus avoid sagging 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 anything else. It’s then
easy to pass the Tile Bridge Support Rails
through the cutout and snap the C-Ring
