Introduction
Thank you for selecting the Community
Commercial Design Series™ of ceiling loudspeakers. Whether you chose them because
they deliver exceptionally high quality sound,
because they have predictable, uniform coverage so spaces are easy to lay out, because they
are easy to install and save time, or because
all models in this series so that you can mix
sizes to optimize the layout without having
disconcerting changes in sound quality. If you
require deeper low frequency response, you
can add D10SUB or DS8SUB subwoofers from
the Community Distributed Design Series of
loudspeakers.

Community designed this series with place-
through-the-cutout Tile Support Bridge Rails
and their snap-on spacers, and Drop-Stop™
installation assistant tabs.
Since the loudspeaker is pre-assembled in the
back-can with its crossover network, and pre-
wired to an external Euro connector, the in-
staller simply inserts the units into the ceiling
These are true coaxial loudspeakers. This
means they have a real compression driver
concentrically arranged so that the upper
frequencies emerge through the center of the
low-frequency driver’s magnetic structure
and cone via a precisely tapered Tru-Phase™
high-frequency waveguide. This special
construction provides consistent, wide dispersion right up to 16 kHz, all but eliminating
high-frequency narrowing. You don’t have the
relection and diffraction problems at multiple frequencies found with “straight tube”
coaxial loudspeakers, simple “whizzer-cone”
in one smooth push of the hand and they snap
in place. They cannot then fall out, thus leav-
ing both hands free to tighten the two clamp
actuator screws, adjust the front-face power
setting dial, and snap on the grille. The wiring
cover plate also serves to clamp non-conduit
carried wires, and the cover does not need to
be removed for access... it just swings clear.
Because one person on a ladder is easily able
to install the loudspeaker in the ceiling, redun-
dant labor is eliminated. Overall, this saves a
tremendous amount of time and labor during
the installation.

Unpacking and Inspection
Community Commercial Design loudspeakers
are engineered and manufactured to be rugged and they are carefully packed in sturdy
cartons. However, it is wise to thoroughly
inspect each unit after it has been removed
from the packaging, as damage could occur
during shipping.
Please note that once the shipment has left
your dealer or the Community factory, the
responsibility for damage is always borne
by the freight company. If damage has occurred during shipping, you must ile a claim
directly with the freight company. It’s very
important to contact the freight company as
soon as possible after receiving your ship-
ment, as most freight companies have a short
time limit within which they will investigate
claims. Make sure to save the carton and the
packing material, as most claims will be de-
nied if these materials are not retained. Your
Community dealer and the factory will try to
help in any way they can, but it is the respon-
sibility of the party receiving the shipment to
ile the damage claim.

Community offers helpful optional accessories that are not included with the basic
packages. Please be sure to order these parts
separately if you need them.
Can Adapter Trim Rings allow you to mount
an entire Commercial Design loudspeaker
assembly into an existing industry back
can that is already in the ceiling from a
previous installation. If you’re performing
a retroit, you will want to order the type of
adapter you need in the size suitable for the
loudspeaker.

The Can Adapter Ring can be used as a Trim
Ring, allowing you to mount a Commercial
Design loudspeaker assembly into an existing
but over-size ceiling cutout hole. When
used as a trim ring, white rubber hole plugs
(included) ill the 4 countersink indents.
A New Construction Bracket is available for
installing loudspeakers in new construction
before drywall or plaster is put in place. The
drywall typically is cut with a router-type
tool or laser guided cutter in which case the
bracket hole will serve as a cutout guide.

Wiring
This manual will serve to assist in wiring
and physically mounting Commercial Design
Series loudspeakers. The directions include
assistance to those installers using a complete Community package of loudspeakers
and accessories, including the integral back
cans, grilles, tile rails and so forth. We include
instructions for use of optional Community
Commercial Design Series retroit adapters
so that Community Commercial Design Series
loudspeakers can be mounted in other manufacturer’s cutouts. If accessory products from
a different manufacturer are used, please refer to the installation manuals supplied with
those products.
Note: All electrical installation connections for loudspeaker lines are subject to all
applicable governmental building and ϔire codes. The selection of appropriate electri-
cal hardware to interface with the Commercial Design Series loudspeaker lies solely
with the installation professional. Community recommends that an appropriately
licensed engineer, electrician, or other qualiϔied professional identify and select the
appropriate conduit, ϔittings, wire, etc. for the installation.
Power Determination
As detailed subsequently, there is no need
to specially select different wire terminals
for 8-ohms or for various 70-volt and 100-
volt power taps. Instead, a face-mounted
tap switch allows you to make this selection.
Once the loudspeaker is mounted correctly
in the ceiling, set the tap switch to the appro-
priate tap setting before any audio is passed
through the loudspeaker. Do not change
the setting on the tap switch while the loud-
speaker is in use.
Installation in back cans without conduit
The only tool required is a screwdriver, which
is provided in the loudspeaker package.
Commercial Design integral back cans include
a swivel-out terminal access cover that also
serves as a cable clamp when tightened in
place. The terminal block in the can’s outer
recess has two (+) connections and two (-)
connections. If you are only connecting one
(dual conductor) cable, you can use either
(+) and (-) terminal, as illustrated on the next
page in Figure 8. If you’re daisy-chaining
a cable to the next loudspeaker, you may
connect the next cable to the remaining (+)
and (-) terminals. There is no need to connect
jumpers or try to stuff two wires into one
terminal block port because each pair of
(+) and each pair of (-) terminals is directly
jumpered together on the input connector.
Installation of conduit to the loudspeaker
Required tools:
• (1) Hammer and knockout punch tool
• (1) Step-bit for adjusting knockout
diameter (optional)
• Safety glasses, gloves and other personal
safety gear are recommended as this process involves striking metal parts and chipping away debris around the knockouts.
1. All Commercial Design Series loudspeaker
back cans have a dual-diameter knockout
strain relief itting on the top cover.
2. The knockout strain relief port is opened
with a hammer and punch using the same
techniques for removing knockouts in stan-
dard electrical boxes.

3. Insert appropriate ittings and tighten
suficiently for wire path concealment and
strain relief, in accordance with applicable
codes.

General
Lay out the loudspeaker locations according
to the requirements of the speciic installation and in compliance with applicable safety
and building codes. It is beyond the scope of
this manual to provide guidance in this area.
Community does, however, offer our Forecast-er HD Distributed Ceiling System Software to
assist you in distributed loudspeaker system
design. Please visit the Product Selection area
of Community’s website for this software.
We also encourage using the provided seismic safety tabs to secure the back cans to the
building structure. Again, please be guided by
applicable building codes here; Community
cannot provide detailed rigging instructions
due to the wide global variations in such
codes and practices.
Figure 10. Cutout template dimensions

Procedure (for suspended ceiling)
Note: The optimum situation for installation
is into a ceiling where the suspension grid is
installed and the tiles have not yet been placed.
Community designed this series to facilitate
installation into an already-placed ceiling, and
we are writing the instructions to conform to
this more restrictive condition. So when we say
something like, “pass the tile bridge support
rails through the loudspeaker cutout,” and
in your situation the adjacent space is unobstructed, of course you should feel free to use
the more sensible alternative and just drop the
rails into place.
1. Mark the hole location on the ceiling tiles
and, using the cutout template provided with
your Commercial Design Series loudspeakers,
cut a hole to the precise size. See Figure 10.
2. Insert the Tile Bridge Support Rails
through the can cutout and position them
across the rails on either side of the cutout,
approximately as far apart as the Bridge Rail
Spacer Bars. Then insert the pair of spacer
bars and clip them over the tile bridge support rails as shown in Figure 11.

Support Rails and Bridge Rail Spacer Bars
3. Make sure mounting clamps are parked
tight against sides of back can before slid-
ing the loudspeaker into the hole, aligning
it so that the mounting clamps are nearest
to the two bridge support rails, labels on
the loudspeaker face indicate the position
of the mount clamps and the required align-
ment. Before sliding the back can into the
ceiling hole, slightly bend each Drop-Stop™
tab outward from the back can 1/2 inch (12
mm). When you press the can fully into place,
the two spring-loaded Drop-Stop™ tabs will
spread atop the bridge support rails, and
you may hear them “snap” into position; you
can now continue without having to hold the
loudspeaker in place. The Drop-Stop tabs are
Community Commercial Design Series Installation and Operation Manual Page 13
designed to drop into the Tile Bridge support
rails channels, they will not work properly if
mis-aligned. See note and Figures 12 and 13
on the next page.
Note: If you’re using loose wires, rather than
conduit, ϔirst connect the wires to the terminal block atop the loudspeaker assembly, and
secure them with the top cover/strain relief,
before installing the can through the cutout
and into place.

to Bridge Support Rails During Installation
4. Locate the two Phillips-head actuators
around the perimeter of the loudspeaker’s
front lange (see Figure 14). Using a #2 Phil-
lips screwdriver twist each actuator clock-
wise until you feel resistance as the clamps
press against the ceiling bridge rails (Fig. 15).
Figure 14. Turning the two loudspeaker
clamp actuators clockwise securely locks
the unit into the ceiling.

Dry-Wall Ceiling Installation.
There are three basic ways to install a Community Commercial Design Series loudspeaker assembly into a drywall ceiling (a.k.a. sheet rock or gypsum board).
Some are for new
construction, others for retroit to existing
construction. We recommend some methods
over others and of course the choice is yours.
A. The preferred method for new in-stallations 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-bystep details and variations.
B. An alternative method for new
installations – where the ceiling has
already been completed – is to use the Tile
Bridge Support Rails. While there are in
fact no truss members across which the
rails it, 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 Figure 15 on
page 14 and to Figure 16 here.

Important! Do not mount the
loudspeaker into any material
without using either the New
Construction Bracket or the
Bridge Support Rails!
Community Commercial Design Series Installation and Operation Manual Page 15
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 17, and refer to the chart
of Figure 2 on page 7 for sizes and model
numbers.
Figure 17. New Construction Bracket for
Drywall or Lath-and-Plaster Installations
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.
Always attach a safety cable
to one or both seismic safety
tabs in all installations. Failure
to do so could result in injury or even
death in the event of a failure of the
primary mounting support system.
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 next Section of this manual for
details). 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 installa-
tion assistant tab outward from the back can
1/2 inch (12 mm). 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 13 on page
14 shows how the Drop-Stop tabs work, and
is equally applicable with New Construction
Bracket installations in drywall ceiling
3. Locate the two Philips-head can
clamp actuators around the perimeter
of the front lange, and using a #2 Phillips
screwdriver twist each actuator clockwise
until you feel tension as the clamps securely
lock the loudspeaker into the ceiling (refer
to Figures 13 and 14 on page 14). These
clamps open fully to 2.35” (59.6 mm), but
we allow at least 0.60” (15.2 mm) 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
” (44.4 mm) thick ceilings can
be accommodated.
Community Commercial Design Series Installation and Operation Manual Page 16
Loudspeaker Tap Setting
You can use a standard #2 or #3 Phillips or a
medium slot-blade screwdriver (not the one
provided with the loudspeaker kit), or just
press thumb irmly, and twist to adjust the
power control dial on the front face of the
loudspeaker bafle. As shown in Figure 19,
you can make any of ive different settings,
although the dial has dual calibrations so at
irst glance it appears to have ten settings.
The 8-ohm position is the same on both sides
and is for a low impedance connection. On
the lower-left side of the power tap control
shown in the close-up on Figure 19 are the
power values for 100-volt connections, and
on the upper right side are the power values
for 70-volt connections.
Note: The letters NC mean “no-connect” but
they do not actually break a connection. DO
NOT USE this setting if you’re using a 100-volt
distribution scheme as the loudspeaker may
draw excessive power; it corresponds to the
highest power that can be drawn with a 70volt source.
Caution: Set the tap switch initially
prior to applying audio, and only
change the switch setting while the
audio ampliϔier is shut off.
This control makes it very easy and fast to
balance an installation since there is no need
to drop the loudspeakers out of their back
cans and move wires to different terminals.

Painting the Loudspeaker
These loudspeakers’ textured white inish
complements most decors and does not require further painting. However, if the interior design requires a custom loudspeaker
inish, these loudspeakers are easy to paint.
It’s best to paint the bafle before installation.
In cases where it needs to be inished along
with the ceiling, the loudspeaker bafle can be
painted after mounting in the ceiling.
Note: The paint masks provided by Community
are intended to PREVENT the loudspeakers
from receiving any paint.
Type of Paint
The loudspeaker’s ABS plastic bafle accepts
almost any type of latex or oil based paint.
We recommend application of two coats.
Painting Process
Follow this procedure to obtain the best
results:
1. Clean the bafle with a light solvent such
as mineral spirits, rubbing the bafle with a
lightly dampened cloth. Do not use abrasives
such as sandpaper or steel wool.
Caution: Use only light mineral
spirits thinner as a cleaner. NEVER
use gasoline, kerosene, acetone,
methyl ethyl ketone (MEK), paint
thinner, harsh detergents or other chemicals.
These chemicals and agents may
permanently damage the loudspeaker and
some are also toxic and highly lammable.
2. Mask the loudspeaker so that the surround, cone and center area will not receive
any paint. If the loudspeaker is already in the
ceiling, you may wish to mask the ceiling as
well. Use a low-tack painter’s tape (typically
blue in color) to avoid damaging the loudspeaker surround when the tape is removed.
We advise against using conventional masking tape and NEVER use duct tape in this
application; these kinds of tape generally
leave adhesive residue that can be dificult to
remove and that may actually cause damage.
3. After cleaning, apply two or more two
thin coats of either latex or oil-based paints.
Latex paint will adhere better if an oil-based
primer is used irst. Apply the paint with a
roller or brush, or spray it on.
4. The grille should be painted separately,
and when it is not in place on the loudspeaker. We further recommend that you remove
the grille’s internal cloth mesh, then spray
paint the grille assembly. Avoid using a roller
or brush to paint the grille as its metal perforated holes may become clogged with paint,
which degrades sound quality and also may
attenuate the sound. Reinstall the internal
cloth mesh (or if damaged install a new cloth
mesh).
Community Commercial Design Series Installation and Operation Manual Page 18
Safety Cabling The Grille
Note: Some codes now require that
the grille have a safety cable; your
local codes may vary. Community
makes it easy to comply with an
included security cable system, as
detailed in Steps 1 through 3 below.
1. Once the loudspeaker is secured in the
ceiling, you can attach the safety cable between the grille and loudspeaker. There is
a nylon mono ilament loop attached to the
grille and looped through a metal clip. Another mono ilament line is located inside the
bass relex port of the face of the loudspeaker.
Use the metal clip to link these two mono ilament loops. See Figure 18.
2. Carefully lower the grille until the cable
holds it, and let go. It should hang harmlessly
from the mono ilament line.
3. If you’re proceeding with setup, you can
leave the grille hanging so you can adjust the
power setting as noted on the next page. Otherwise, install the grille into position on the
face of the loudspeaker bafle.
Figure 19. Grille Safety Clip and Line (left) Should Look Like This (right) When Attached.
