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. they are very competitively priced for such a high-performance loudspeaker, you can have conidence you made the right choice.
Their high power handling, high sensitivity,
and therefore higher overall output capacity

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 relection 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. loudspeakers, or front-mounted soft dome high frequency loudspeakers (typically found in ceiling speakers at this price point) that at­tempt to emulate a true coaxial design.
Community does not use OEM or off-the-shelf utility loudspeakers in the Commercial Design Series. We designed these units from the coil formers to the back cans. We expended great

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.

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 retroit 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.

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.

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.

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).

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 retroit 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!

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.

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 bafle. 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 bafle before installation. In cases where it needs to be inished along with the ceiling, the loudspeaker bafle 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 bafle 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 bafle with a light solvent such as mineral spirits, rubbing the bafle 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 dificult 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).

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 relex 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 bafle.
