Introduction
Thank you for selecting the Community Distributed found in ceiling speakers at this price point) that
Design Series™ of ceiling loudspeakers. attempt to emulate a true coax design.
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 they are very competitively priced for such a high-performance, durable loudspeaker, you can have confidence you made the right choice.
The Distributed Design Series is built to satisfy safety agency standards, with quality assured by Community’s long history of building highperformance, durable loudspeakers for sound reinforcement and contracting applications.
The Distributed Design Series is comprised of these seven models:

Each model is available as a complete assembly, including everything needed for standard installations, or you can purchase packages for the face portion only or the back can portion.
Each of these packages has components for two loudspeakers. The D4LP Low Profile model fits where deeper units cannot and may be retrofitted into existing shallow cans.
Except for the D10SUB subwoofer, each of the other six models is a true coaxial loudspeaker.
This means it has 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™ highfrequency waveguide. This special construction provides consistent, wide dispersion right up to 16 kHz, all but eliminating high-frequency narrowing. You don’t have the reflection and diffraction problems at multiple frequencies found
(and its’ concentric HF driver) dead-center in the baffle, as contrasted to the offset designs used by many others.
where the grille is attached, and the low-frequency driver is rear-mounted behind the grille plate.
Such designs produce unwanted reflections and diffraction effects such as frequency response peaks and nulls, polar irregularities, and phase response problems. To avoid these issues,
Community Distributed Design baffles are very close to the grille (less than 1/8 inch away).
The loudspeaker baffle and ceiling thus form an uninterrupted planar surface for diffractionfree HF driver acoustic loading and a smooth, predictable pattern. This makes it easy to lay out your loudspeaker installation for optimum coverage without those unwanted dead zones or too-loud overlaps.
The Distributed Design Series saves you money in several ways. (a) Their powerful magnetic structures and efficient coils ensure high output, which gives you more headroom per power amplifier so you can use a smaller amp that will save you money. (b) These loudspeakers are very competitively priced and (c) Community designed this series with place-through-the-cutout Tile
Support Bridge Rails, Drop-Stop™ installation assistant tabs, Twist-Assist™ loudspeaker face retainer tabs, and other innovations so that one person on a ladder is easily able to install the loudspeaker in the ceiling. Overall, this saves a tremendous amount of time and labor during the installation. You can use 8-ohm or constant voltage distribution for which you get a 70 volt /
100 volt transformer built in.
We urge you to read these instructions carefully and familiarize yourself with the features and contact Community right away.
with "straight tube" coaxial loudspeakers, simple
"whizzer-cone" loudspeakers, or front-mounted
Further pattern improvement is achieved by precisely mounting the low frequency driver
Most competitive ceiling loudspeakers typically have a half-inch or greater, "step" in their face installation methods before you begin the job.

Optional Accessories
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.
Retrofit rings are available in two types for various loudspeaker group sizes. The Face Adapter
Ring allows you to place the Distributed Design loudspeaker alone in a non-Community made back can. The Can Adapter/Trim Ring allows you to mount an entire Distributed Design loudspeaker assembly with its Community back can in a larger non-Community back can or to mount the loudspeaker assembly into an existing but oversize ceiling cutout hole. If you’re performing a retrofit, you will want to order the type of adapter you need in the size suitable for the loudspeaker.
(These rings are not offered for the 8 or 10 inch diameter loudspeakers.) As suggested by its name, the Can Adapter ring can be used as a
Trim Ring. When used as a trim ring, white rubber hole plugs (included) fill the 4 countersink indents intended for mounting the ring to an existing larger industry back can
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.

• One hammer and knockout punch tool
• One 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.
2. The knockout strain relief ports are opened with a hammer and punch using the same techniques for removing knockouts in standard electrical boxes. A step-bit can be used to modify the diameter of the hole to accommodate larger conduit sizes.
1. All Distributed Design Series loudspeaker back cans have dual-diameter knockout strain relief fittings on each side. These fittings each measure:
• 21/32 fittings

Installing the Back Can in the Ceiling
General
Lay out the loudspeaker locations according to the requirements of the specific 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 Forecaster ceiling system software to assist you in distributed loudspeaker system design. Please visit the Product Selection area of Community website for this software.
We also encourage you to use the provided seismic safety tabs to secure the back cans to the building structure. Again, please be guided by applicable building codes here; we cannot provide detailed rigging instructions due to the wide global variations in such codes and practices.
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. We 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 can cutout," and the adjacent space is unobstructed, of course you should feel free to use the more sensible alternative and just drop the rails into place.
Figure 24 Cutout template dimensions
3. Guide the C-ring support plate through the cutout hole and position it centered in the hole and aligned so its attachment clips are closest to the tile bridges you just placed. Slide these bridges as necessary so the C-ring clips can be pressed onto the raised rail ribs, and now snap the C-ring clips onto the rails. See Figure 25.
1. Mark the hole location on the ceiling tiles and, using the cutout template provided with your
Distributed Design Series loudspeakers, cut a hole to the precise size. See Figure 24.
Attachment Clips
2. Insert the 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 clips on the C-ring support plate. See
Figure 25.
Note: The bridge support rails each have a raised rib with a flat stabilizing flange on one side which keeps the rail from tipping toward the loudspeaker it is supporting.
For this reason, be sure to place the rails so that these stabilizing flanges are facing inward toward the cutout.
Stabilizing flanges

4. Slide the back can into the hole, aligning it so that its input terminal block OR its knockout strain relief locations are consistent with the wiring distribution you have mapped out. When
5. Locate the four Phillips-head can clamp actuators around the perimeter of the back can’s front flange (see Figure 27). Using a #2 Phillips screwdriver twist each actuator clockwise until you press the can fully into place, the four spring-loaded Drop-Stop™ tabs will spread atop the C-ring, and you may hear them "snap" into position; you can now continue without you feel resistance as the can clamp presses against the ceiling. having to hold the can in place. See Figure 26.

(Temporarily holds can in place even before you secure it with the steel mounting clamps)
Figure 27 Turning the can clamp actuators clockwise securely locks the back can into the ceiling
Rotate the back can as necessary to ensure all of the clamps are oriented to contact and compress the C-Ring to the ceiling tile during step five as follows.
Note: If you’re using loose wires, rather than conduit, it makes sense to first connect the wires to the terminal block atop the can, and secure them with the top cover/ strain relief, before installing the can through the cutout and into place in the C-Ring.
6. This concludes a single back can installation for a standard suspended ceiling. Repeat for as many loudspeakers as you need to install.
Refer to page 28 for instructions on installing the loudspeaker into the back can.

Dry-Wall Ceiling Installation
There are four basic ways to install a Community
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 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.

C. drywall ceiling
Use the Tile Bridge Support Rails and C-Ring Support Plate.
Retrofit a Distributed Series Loudspeaker
(driver/face plate without back can) into an existing back can using a corresponding Distributed
Series Face Adapter Ring.
B.
An alternative method for new
installations – where the ceiling has already been completed – is to use the C-Ring Support
Plate along with the Tile Bridge Support 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
Support Plate on top of them. Refer to Figure 25 on page 23 and to Figure 28.
D.
Retrofit an entire Community Distributed
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 loudspeaker 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.
Community Distributed Design Series Installation and Operation Manual Page 25
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.
Inserting the Loudspeaker Assembly into the
Back Can
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. Slide the back can into the hole. When you press the can fully into place, the four Drop-Stop installation assist tabs will spread atop the C-ring, 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 26 on page
24 shows how the Drop-Stop tabs work, and is equally applicable with C-Ring Support Plate or
New Construction Bracket installations in drywall ceilings.
Figure 29 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.
3. Locate the four Phillips-head can clamp actuators around the perimeter of the back can’s front flange, and using a #2 Phillips screwdriver twist each actuator clockwise until you feel tension as the clamps securely lock the back can to the ceiling (refer to Figure 27 on page 24).
The back cans leave the Community factory with these clamps fully open (so that approximately
1.5" / 38 mm thick ceilings can be accommodated).
Note. If you are thinking of using the Can
Adapter/Trim Ring to fit a complete Community
Loudspeaker Assembly into an existing oversize ceiling hole, PLEASE DO NOT! We do not
recommend this practice. The loudspeaker has minimal support and is more apt to cause the ceiling to sag. Also, this almost certainly would not satisfy seismic codes if any such codes are applicable.
Community Distributed Design Series Installation and Operation Manual Page 26
Painting the Loudspeaker
The loudspeakers’ textured white finish complements most decors and does not require further painting. However, if the interior design requires a custom loudspeaker finish, these loudspeakers are easy to paint.
It’s best to paint the baffle before installation. In cases where it needs to be finished along with the ceiling, the loudspeaker baffle 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 baffle accepts almost any type of latex or oil based paint. We recommend application of two coats.
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 first. 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).
Painting Process
Follow this procedure to obtain the best results:
1.
Clean the baffle with a light solvent such as mineral spirits, rubbing the baffle 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 flammable.
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 difficult to remove and that may actually cause damage.
Community Distributed Design Series Installation and Operation Manual Page 27
Secure the Loudspeaker In the Back Can
When you have made the electrical connections from the wires coming into the can to the loudspeaker then you can mount that loudspeaker into the can.
2. Twist the loudspeaker clockwise a few degrees so the Twist-Assist™ face tabs are positioned at the left of the face slots as you look at the front face (see Figures 30 and 31).
1. Four Twist-Assist™ face tabs protrude just inside the can opening. Align the four slots along the periphery of the loudspeaker face with the
Phillips-head can clamp actuators. The actuators should be positioned so that they are at the far right of the slots (viewed through the slot from the front of the loudspeaker).
3. Four 4mm sheet metal screws come from the factory partially inserted into the plastic face.
Use a screwdriver to install these captive screws into the can. Tighten so they are snug against the face, but do not over-tighten them. See Figure 32.
Note: Some codes now require that the grille have a safety cable; your local codes may vary. In any case, Community makes it easy to comply with an included security cable system, as detailed in Steps 4 through 6.

4. Once the loudspeaker is secured in the back can, you can attach the safety cable between the grille and loudspeaker.
There is a nylon mono filament loop attached to the grille and looped through a metal clip. Another mono filament line is located inside the bass reflex port of the face of the loudspeaker. Use the metal clip to link these two mono filament loops.
See Figure 33.
5. Carefully lower the grille until the cable holds it, and let go. It should hang harmlessly from the mono filament line.
6. 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, snap the grille into position on the face of the loudspeaker baffle.

Community Distributed Design Series Installation and Operation Manual Page 29
Loudspeaker Tap Setting
You can use a standard #2 or #3 Phillips or a medium slot-blade screwdriver such (not the one provided with the loudspeaker kit), or just press with your thumb firmly, and twist to adjust the power control dial on the front face of the loudspeaker baffle. As shown in Figure 34, you can make any of five different settings, although the dial has dual calibrations so at first 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 left side of
Figure 34’s closeup detail view are the power values for 100-volt connections, and on the right side the power values for 70-volt connections.
(The actual power values on this dial will vary with the model of loudspeaker installed.)
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 70-volt source.
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.
