UNPACKING AND INSPECTION
CLOUD12 loudspeakers are inherently rugged and 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 file a
claim directly with the freight company. It’s very important to contact the freight company as soon as
possible after receiving your shipment, 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
denied 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 responsibility of the party receiving the shipment to file the damage claim.
It’s always a good idea to retain the carton and packing materials indefinitely, if po ssible, in the event that
the unit may need to be returned to your dealer or distributor for repair in the future.
Each shipping carton contains the following items:
• CLOUD12 ceiling loudspeaker mounted on a standard ported baffle (Qty 1)
• Four 8/32 screws (for mounting the baffle to a C12BB3 backbox sold separately)
• Operation manual (Qty 1)
• Warranty card (Qty 1)

CLOUD12 OVERVIEW
Thank you for purchasing your new Community CLOUD12 Series High Output Ceiling Loudspeakers. The
CLOUD12 and CLOUD12SUB ceiling loudspeakers are extremely high output devices, intended to m eet the
needs of the professional sound contractor for a variety of professional sound installation applications.
Available in either 60 x 60 degree or 90 x 90 degree coverage patterns, and in both 8 ohm and 70V/100V
formats, the 12-inch woofer and high output co-axially mounted 1-inch tweeter deliver high quality sound
over a wide coverage area. For installation s that require extra bass output, the CLOUD 12SUB provides a
matched 12-inch ceiling-mount subwoofer.
The CLOUD12 and CLOUD12SUB are provided with multi-terminal barrier strips for amplifier connection. The
70V/100V versions of the CLOUD12 and CLOUD12SUB are provided with the following 70V wattage taps:
25/50/100/200W. For applications outside North America, the following 100V taps are offered:
50/100/200W.
The CLOUD12 and CLOUD12SUB loudspeakers employ Community's advanced technology DYNA-TECHTM
driver protection system. Functioning as a multi-stage limiter, DYNA-TECH circuitry provides precise and
repeatable protection by reducing excessive power to the drivers under abusive conditions. There are
numerous advantages to this type of multi-stage protection circuitry. The trip point is pre-set to engage at
exactly the same time on all loudspeakers that are powered from the same amplifier. The initial stages of
DYNA-TECH protection circuitry do not rely on, and are not affected by heat build-up. If the system is
operated in the second-stage mode of protection for a long period of time, or if the input level is increased
to try to overcome the volume drop from the second-stage protection circuitry, a solid-state circuit breaker
will trip and remove all signal from t he loudspeaker until the input level is reduced. Because this circuit
breaker is heat sensitive, it provides a final level of protection that takes heat into account as well as power.
The CLOUD12 and CLOUD12SUB come mounted on a standard ported baffle, and are equipped with eight
(8) mounting points for industry standard backboxes. Each package includes four (4) 8/32 screws for
mounting the baffle to a backbox.
The CLOUD12 and CLOUD12SUB can be flush-mounted into any ceiling type, or alternatively can be
suspended in an open ceiling. For proper installation, the CLOUD12 assembly must be mounted to a
backbox, such as the Community C12BB3 heavily braced 3.0-cubic foot metal backbox. Additional
accessories av ailable for the CL OUD12 include the C12SQGRL square white grille, and installation channel
rails in 23.75-inch, 30-inch and 47.75-inch lengths (RAIL24-PR, RAIL30-PR and RAIL48-PR, respectively).

and channel rails are assembled together. Please note that the C12BB3 ships as a backbox only, and all
other parts shown are optional accessories.
Community CLOUD12 – Operation Manual - Page 14
WIRING AND INSTALLATION
This manual will serve to assist in wir i ng and physically mounting CLOUD1266, CLOUD1266T, CLOUD1299,
CLOUD1299T, CLOUD12SUB and CLOUD12SUB-T loudspeakers. The directions include assistance to those
installers using a complete Community package of loudspeakers and accessories, including the C12BB3
backbox, C12SQGRL square grille and appropriate tile rails. If accessory products from a different
manufacturer are used, please refer to the installation manuals supplied with those products.
For protection against electrical shock and to meet the requirements of the UL2043
standard, the speaker assembly must be installed in a Listed Community Model C12BB3
Back Box or similar UL1480/UL2043 listed enclosure. Minimum dimensions for the
enclosure must be 23” wide x 20” deep by 12” tall with a minimum wall thickness of
1.2mm.
Installing Backbox Fittings for Conduit and Strain Relief
Required tools:
• 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.
NOTE: All electrical installation connections for speaker lines are subject to local, state, and federal
building & fire codes. The selection of appropriate electrical hardware to interface with the C12BB3
lies solely with the installation professional. Community recommends that an appropriately licensed
engineer, electrician, or other professional identify and select the appropriate conduit, fittings, wire,
Instructions for installing bac kbox fittings for c onduit and strain rel ief:
etc. for the installation.
1. The C12BB3 comes equipped with knockout fittings on each side panel measuring:
a. 21/32” (17mm) to accommodate 3/4” fittings
b. 15/16” (24mm) to accommodate 1” fittings
2. The knockouts are removed with a hammer and punch using the same techniques for removing
knockouts in other types of electrical boxes. A step-bit can be used to modify the diameter of the
knockout to accommodate larger conduit sizes.
3. Insert appropriate fittings and tighten sufficiently for wire path concealment and strain relief, in
accordance with applicable codes.
4. The acoustical damping batting material on the interior of the C12BB3 backbox should not cover the
inside surface of knockouts. If the batting covers the knockouts, peel back about four inches to
expose the knockouts. Trim off any excess batting that has been peeled back so that it will not
interfere with the loudspeaker’s function.
White mastic acoustical material on the C12BB3 (looks like white plaster) can be chipped away as needed to
allow electrical fittings to seat securely on the metal surface surrounding the knockout.

Connecting the Loudspeaker Cable for 8 Ohm (Low Impedance)
Figure 16: Attaching the loudspeaker cable to the CLOUD12 input panel
Connections
Connect the common side of the speaker cable to the " - " terminal on the input block. Connect the positive
side of the speaker cable to the " + " terminal on the input block. 14 AWG twisted pair speaker cable is
recommended for most 8 ohm applications w hen using spade or ring terminals. The speak er in p ut block will
accept up to 10 AWG cable directly without spade terminals. For multiple speakers, attach the subsequent
speakers by parallel connecting them to the " - " and " + " input terminals of the previous speaker.
NOTE: Community recommends crimping a spade terminal (1/4” width spade) to the end of the
speaker wire prior to connection to the terminal block. In the absence of spade terminals, wire
ends can be stripped ¼” (7mm) and connected to the terminal block. Be careful not to strip too
much as frayed wire ends can short across the terminal block. Ring terminals do not fit.

Connecting the Loudspeaker Cable for 70V/100V Connections
Connect the common side of the speaker cable to the “common” terminal on the input block. Connect the
positive side of the speaker cable to the appropriate 70V/100V wattage tap ba sed on the requirements of
the project. For multiple 70V/100V speakers, attach the subsequent speakers by parallel connecting them to
the “common” and appropriate autoformer input terminals of the previous speaker.
NOTE: Community recommends crimping a spade terminal (¼" width spade) to the end of the
speaker wire prior to connection to the terminal block. In the absence of spade terminals, wire
ends can be stripped ¼" (7mm) and connected to the terminal block. Be careful not to strip too
much as frayed wire ends can short across the terminal block. Ring terminals do not fit.

CLOUD12SUB Ceiling Mount Subwoofer Overview
The CLOUD12SUB ceiling subwoofer is the same size and weight as the full-range CLOUD12 Series of ceiling
loudspeakers. All mechanical assembly and installation instructions and procedures are the same for the
CLOUD12SUB as the full-range assemblies. The autoformer tap selections on the 70V/100V version
CLOUD12SUB-T and the full-range assemblies are identical. Differences in sensitivity among the various
models will require different wattage taps, and all amplifier power is calculated using the total number of
loudspeakers, regardless of the mix of full-range and subwoofer assemblies.
Community CLOUD12 – Operation Manual - Page 18
NOTE: The electrical damping factor of the subwoofer amplifier is a critical factor when selecting
Figure 18: CLOUD12SUB and CLOUD12SUB-T
CLOUD12SUB-T (70V/100V OPERATION)
CLOUD12SUB (8 OHM OPERATION)
equipment to support the CLOUD12SUB. Damping factor refers to the power amplifier’s ability to
stop (or “dampen”) a reproduced frequency. The higher the dam ping factor, the better the amplifier
will control the LF driv er. Bass frequencies are more difficult to control than higher frequencies, and
therefore the damping factor becomes more important to the overall system. The higher the
damping factor, the better the amplifier will control the LF driver. The damping factor of an amplifier
is dependent largely on its output impedance. A high damping factor indicates that an amplifier will
have greater control over the movement of the speaker cone, particularly near the resonant
frequency of the driver’s mechanical resonance. Community recommends that the damping factor of
the subwoofer amplifier be greater than 1 00 @ 8 oh ms . Additionally, th e cable ch osen sh ould be a t
least 14 AWG for optimum LF reproduction with minimum line loss and minimum reduction in
damping factor. It should be further noted that damping factor is more of an influence in a low
impedance (8 ohm) system than a high impedance (70.7V) system.
The CLOUD12SUB ceiling subwoofer is shipped with 24 inches of two-conductor, 16 AWG speaker cable
attached via crimped spade terminals on one end. The other end is stripped and ready to connect via wire
nut to incoming cable. See the figure below for input terminal designation.

•
Attaching Channel Rail Kits to the C12BB3 Backbox
Community offers rail kits in three popular lengths: 24 inches, 30 inches and 48 inches. Choose the
appropriate size kit to fit the architectural structural supports for the CLOUD12 speaker and C12BB3
backbox assembly. The CLOUD12 speaker system is meant primarily for installation in ceilings, and these
instructions follow that path. Other installation locations, such as in walls, are also possible.
Rail kits can be installed directly to the building structure, and can be used to create additional rigging
solutions. Please remember that when using rail kits for rigging supported by st eel wire, rope, chain, or
similar materials, the center of gravity of the assembly might be above the attachment points on the rail kit.
NOTE: The rail itself may not provide sufficient stiffness if rigged from a point located far
from the backbox tabs. Community recommends all mounting and rigging methods be
approved by a qualified Professional Engineer.
Required tools:
• Two 7/16” (11mm) wrenches, socket drivers, or spin-tights (nut drivers).
• Torque wrench (as needed) to verify proper fastener torque.
Community CLOUD12 – Operation Manual - Page 20
Figure 21: Channel rail kit with tools and accessories
Instructions for a tt aching the channel rails to the backb ox :
1. Unpack the RAIL24-PR, RAIL30-PR, or RAIL48-PR kit and find the following contents:
a. Two mounting rails
b. (4) 1/4-20 x 1” Hex Head Screws
c. (4) 1/4” Hex Nuts
d. (8) 1/4” Flat Washers
e. (4) 1/4” Lock Washers
f. Liability Waiver Card
2. Set rail along one side of the C12BB3 backbox so that the leg of the rail aligns with the slotted ho l es
against the slotted tabs.
3. Orient the leg with the row of ten 9/32” holes in th e desired direction for it to fasten to the building
structure. The installer will likely orient the rail so that this leg faces the same direction as the
speaker and will rest on top of the ceiling structure. However, keep in mind there are oth er
installation scenarios that require placing the rail in the opposite orientation.
4. Assemble the hex screws hardware. For each ta b location, use one hex screw, one hex nut, two
washers, and one lock washer.
5. Tighten the hex screws to a maximum 10 lb-ft torque.
6. Repeat the above steps for the other rail on the other side of the C12BB3.
7. Please note that the slotted hole in the rail can be used to adjust the position of the rail horizontally
for best installation location.
8. Please note also that the slotted tab on the C12BB3 permits the rail to be adjusted vertically to
adjust the trim height of the loudspeaker in the ceiling.

Figure 22: Tightening the rail kit to the backbox
Suspending the C12BB3 Backbox
The C12BB3 backbox will generally be installed in tile-based ceiling systems, but can also be installed in
open space. Use eyebolt kits (part number 1/4EYBLTKIT) to fasten conventional rigging hardware to the
C12BB3.
Required Tool:
Instructions for suspending the backbox using eyebolts:
NOTE: There are several 1/4-20 suspension points located in the back panel of the
C12BB3. These can be used as alternate support and rigging points for open ceiling plan
installation. Community recommends all mounting and rigging methods be approved by a
qualified Profess i onal Engineer.
• Stiff screwdriver (or similar tool) f or snugging eyebolts
1. Unpack the 1/4EYBLTKIT and find the following items:
a. (4) 1/4” Forged Shouldered Eyebolts
b. (4) Cup Washers
2. Set aside (4) cup washers as they are not used for this application.
3. Insert one eyebolt kit in each suspension point and turn it until seated snug on the rear of the
cabinet surface.
4. Do not over-tighten the eyebolt. Once seated, the eyebolt will only need 1/8-turn to ¼-turn to
firmly tighten. Insert a stiff tool through the eye to help “snug” the eyebolt into position, but do not
use that as a tightening (or “torquing”) tool.
5. In some cases shims (not included) will be necessary to adjust the orientation of the eyebolt so that
the plane of the eye correctly aligns with the direction of the attached suspension cable.
6. The eyebolts should be installed tight enough to prevent accidental unfastening, but not tight
enough to damage the insert threads.

Figure 23: “Snugging” the ¼-inch eyebolts
Figure 24: Eyebolt load ratings
Eyebolt Suspension:
The eyebolts must be screwed in so that the shoulder firmly contacts the surface of the enclosure. In all
cases the direction of pull on the eyebolt and mounting point should not exceed a maximum of 45º from the
vertical axis of the mounting point hole. Multiple cables that can independently support the loudspeaker
must also be used. See the following figure.
NOTES:
• There is no benefit in tightening the eyebolt more than hand tight. Never pull an eyebolt sideways
or at 90° to a vertical pull angle.
• The CLOUD12 family of loudspeaker assemblies must be installed in a backbox prior to permanent
installation. In order to conform to local electrical codes, do not install any CLOUD12 loudspeaker
assembly in a ceiling without an appropriate backbox such as the Community C12BB3.
• The CLOUD12 loudspeakers can generate substantial vibrations, which can cause the ceiling tile or
other parts of the support structure to audibly buzz. Depending on the nature of the ceiling tile and
the overall structure, the installer may elect to adhere dampening material (not provided) such as
neoprene under the tile rails or the edges of the tiles themselves to eliminate buzzing or rattling.

Attaching the CLOUD12 Loudspeaker to the C12BB3 Backbox
Figure 25: Proper handling of the CLOUD12 loudspeaker
NOTE: The CLOUD12 loudspeaker weighs approximately 20 lbs and the C12BB3 backbox
weighs at least 40 lbs. Both are awkward and difficult to handle. Lift the CLOUD12 by the
speaker basket or main support backing only; do not use the terminal strip or the autoformer
(70V/100V versions only) as a lift point. It is highly recommended that two people work as a
team to install the C12BB3 backbox into the ceiling and the CLOUD12 assembly into the
backbox. Beware of sharp edges on the cast woofer basket. These are a normal remnant
of the casting process.
Required tools:
• One #2 Philips Screwdriver
• Safety glasses and other related personal safety gear are always recommended when working
overhead.
• It is highly recommended that two people participate in this portion of the installation. Placing and
installing loudspeaker assemblies in a ceiling is a dangerous enterprise for one person to undertake.
Instructions for a tt aching the CLOU D 12 to the backbox:
1. Refer to instructions in this manual related to suspending the C12BB3 and supporting the C12BB3
safely.
2. Make all necessary conduit or other wire path ingress installations before proceeding with the
installation. For more information on interfacing common conduit fittings with the C12BB3, please
refer to the portion of this manual addressing that topic.
3. After removal of the CLOUD12 loudspeaker from the shipping container, find the following items:
Parts List for fastening CLOUD12 Loudspeaker to C12BB3 backbox:
(1) CLOUD12 Ceiling Loudspeaker (1) Warranty Documentation
(4) 10-24 x 1/2" Philips Truss Head Screws (1) Warranty Registration Card
(4) #10 Flat Washers (1) Waiver of Liability Card
(4) #10 Lock Washers (1) Installation and Operation Manual
(4) 8/32 Screws (1) Specification Sheet
4. Refer to instructions earlier in this manual to make the necessary electrical connections to the
loudspeaker’s amplifier circuit, being careful to observe polarity and to use the correct taps for
transformer-equipped (70V/100V) units.
Community CLOUD12 – Operation Manual - Page 24
5. Set the CLOUD12 into the square hole in the C12BB3. Handle the speaker assembly by its metal
frame or baffle plate. Be careful to not handle the weight of the assembly by the electronic parts or
the speaker’s paper cone. It will likely require the assistance of a second worker to hold the
CLOUD12 speaker assembly. Alternately, a fixture might be devised to safely support the speaker
frame while fastening it into the C12BB3.
6. Be sure that the neoprene rubber gasket material surrounding the outer edge of the speaker frame
makes contact and seals all the way along the perimeter of the raised square flange on the C12BB3.
7. Insert and start threading all four 10-24 x ½" Philips Truss Head Screws using one #10 Flat Washer
and one #10 Lock Washer as shown in Figure 12. After all four screws have been threaded one or
two turns; tighten screws hand-tight so that the neoprene gasket is evenly compressed. Do not
over-tighten the Philips head screws, but do take care to ensure that they are firmly seated and that
the lock washer has compressed.
8. Check and review that all steps above have been carefully followed.

Attaching the C12SQGRL Grille to the CLOUD12/C12BB3 Assembly
Figure 28: C12SQGRL grille in place on the CLOUD12 assembly
Required tools:
• One #2 Philips Screwdriver
• Superlative vision and a flashlight to see the tiny black holes behind the grille when inserting the
screws
• Safety glasses are highly recommen d ed
Instructions for a tt aching the grille to the loudspeaker a nd backbox assembly:
1. Unpack C12SQGRL and inspect contents to find the following:
(1) C12SQGRL white grille
(4) 8-32 x 1-1/2” Philips truss head screws
2. The C12SQGRL is provided in white. The grille can be painted if another color is desired. Use a high
quality spray paint only. Prior to painting, the surface should be treated to remove the sheen from the
polyester powder coating. This can be done with fine grit sanding or chemical sheen removers such as
trisodium phosphate. Primer and finish coat paint is applied in the same manner as other metal
surfaces. If the C12SQGRL grille is roller or brush painted, the mesh material may become clogged with
paint, resulting in attenuating of high frequencies and subsequent poor sound.
3. Please note the two locations at each corner of the CLOUD12 loudspeaker baffle plate for
attaching grilles. The holes closer to the perimeter of the baffle plate are used for the
C12SQGRL. The holes closer to the speaker cone are used for other manufacturer’s
compatible grilles.
4. Place the C12SQGRL grille over the face of the CLOUD12 loudspeaker so that the edges of the grille
wrap around and conceal the edges of the baffle plate and surrounding ceiling material.
5. Line up one of the 8-32 x 1-1/2” Philips truss head screws through one hole in the C12SQGRL and insert
it into the correct hole in the CLOUD12 baffle plate. Turn the screw one or two turns to get it started.
Repeat this process for the remaining three screws.
6. Carefully snug all four mounting screws evenly so that both edges of the grille make firm contact with
surrounding ceiling material or so that the upper surface of the grille makes firm contact with the baffle
plate (for installations where the CLOUD12 speaker and backbox are installed in free space).
7. Be su re the grille is tightened enough to be securely fastened to the CLOUD12 loudspeaker, and snug
enough to the ceiling material (or the baffle) so that the grille does not vibrate.
