Introduction
Thank you for selecting Community’s W SERIES W2 premium all-weather/all-purpose installation loudspeakers.
WET is an acronym standing for Weather Environmental Technology, which describes one of the main design
goals of this product line.
W2 products are built using unique weather-resistant materials that can survive sustained exposure to harsh
climatic conditions. In addition to weather-resistance, these materials also possess favorable acoustical
properties. The result is a line of loudspeaker products that not only performs consistently in tough,
problematic environments, but also provides superlative acoustic performance, typically associated only with
high fidelity “indoor” loudspeakers.

Unpacking and Inspection
W2 loudspeakers are inherently rugged and are carefully packed in well-designed 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 is 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 is always a good idea to retain the carton and packing materials, if possible, 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:
•Loudspeaker System (Qty 1)
•Information packet with Operation and Installation Manual (Qty 1)
•Mounting Yoke for W2-218, W2-228 and W2-2W8 models only (Qty 1)

W2 Loudspeaker Systems from Community
The W2 models from Community combines all of WET’s original weather-defying characteristics with improved
styling and technology. W2 models are entirely constructed of corrosion-resistant materials like fiberglass,
stainless steel, polyimide and carbon fiber, using sophisticated technologies to ensure they will withstand
exposure to harsh environmental conditions.
W2 loudspeakers have been designed to be highly weather-resistant. W2 enclosures are fabricated entirely of
hand-laminated fiberglass, making it virtually impervious to weather-related effects. The drivers and their
diaphragms are made of highly weather-resistant materials, as in the case of the mid and high frequency
drivers, or are treated to repel moisture, as in the case of the low frequency drivers. All external hardware on
the loudspeaker is stainless steel. The three-layer Weather-Stop™ grille is acoustically transparent but highly
resistant to moisture intrusion. The crossover is located within a sealed chamber that forms the enclosure for
the low frequency drivers. A weather-tight gland nut provides a seal for the input cable. The input cable is a type
SJOW with neoprene insulation which is resistant to weather and UV effects.
W2 products offer a wide range of power levels, frequency response capability, and directional pattern control.
The W2 product line consists of a basic complement of six sizes of loudspeaker enclosures with multiple
dispersion patterns available in three of size formats.
The models in this range include:
•The W2-218 compact two-way, 8-inch full-range system
•The W2-228 quasi three-way, 8-inch full-range system
•The W2-2W8 compact two-way, dual 8-inch, fill loudspeaker with ultra-wide 120° HF pattern control
•The W2-312 three-way, 12” full-range system
•The W2-112 single 12” subwoofer system
•The W2-122 dual 12” subwoofer system
•The W2-125 dual 15” subwoofer system
W2 features greater precision and tighter tolerance fit. Frequency dividing networks have been fine-tuned for
improved acoustical linearity. Plus, a low-loss, low-distortion 200 Watt high fidelity autoformer has been
developed and is optionally available for 70V/100V applications in the W2-218, W2-228 and W2-2W8.
While handling outdoor applications with ease, the elegant styling of W2 makes them suitable for many indoor
applications as well. All W2 systems are available in standard black or white fiberglass finishes, with an
enclosure-matching black or white marine-grade grille finished with Community's powder-coating process.
White W2 enclosures include matching white grilles, white bezels, white gland nuts, and white cable, making
them perfect for cruise ships, clubs or residential applications. Custom color exteriors are also possible at a
nominal fee.
A black or white powder-coated stainless steel mounting bracket is included with smaller models W2-218,
W2-228 and W2-2W8, while optional mounting accessories are available for the larger full-range and
subwoofer systems. W2 models are protected by a five-year product warranty plus a fifteen-year enclosure
warranty. W2 loudspeakers are flexible, easy to install and most importantly, they provide unparalleled sound
quality. They are designed to withstand sustained use under severe climatic conditions, functioning year after
year in even the harshest environments.
This manual is intended to help you install and use W2 loudspeakers safely and effectively. It provides useful
information to help you obtain the best performance, sound quality, and reliability from your W2 systems. We
have provided a series of Quick-Start diagrams to enable you to install and operate the products immediately if
required; however, we recommend that you read this manual in its entirety, to help insure that your W2
installation meets the highest possible standards. While every attempt has been made to ensure this
information is correct and up-to-date, Community continuously incorporates worthwhile improvements to each
product, which may include changes and/or modifications not contained in this manual.

Important Note – Mounting/Rigging Provisions
The mounting/rigging points found on the sides and back of the enclosure must either be used for mounting
hardware or “plugged” with the bolts and washers provided. The rubber washer provides the water seal and
must be used. The reason for this is that if all these holes are not plugged up, they created leaks in the
enclosure that will compromise its weather-resistance. Open holes will also be detrimental to low frequency
performance with reduced output and/or distortion.
DANGER: All rigging fittings must be fitted with either optional mounting hardware or they must remain
sealed with the Stainless Steel hex-head bolts that come installed in the enclosure, in order to maintain
weather resistance. Additionally, if the rigging fittings are not sealed, air leaks could occur in the
enclosure that will compromise the low frequency performance with added distortion and reduced
output.
WARNING: W2 rigging fittings are rated at a Working Load Limit of 150 lbs (68 kg) per point. No single
rigging fitting should ever be subjected to a load that is greater than 150 lbs. Failure to heed this
warning could result in injury or death!
W2 Features and Technology
In addition to extreme weather-resistance, W2 loudspeakers offer numerous features and advances in
technology that provide unprecedented sonic quality and installation flexibility. Some of these include:
•Finely tuned internal crossover networks for reduced off-axis lobing, consistent coverage throughout
the crossover region, and greater acoustic linearity.
•Uniform-voicing filters minimize sonic variations among the different models.
•Geometrically correct large-format hand-laid fiberglass mid and high frequency horns. A wide selection
of dispersion patterns is available.
•Aesthetically pleasing, uniquely shaped curved fiberglass enclosures. The enclosure composition and
the enclosure geometry work together to reduce internal reflections and standing waves, resulting in
superior sound quality. Externally, the lack of flat surfaces minimizes water buildup.
•Envirotech coating seals crossovers against moisture.
•Stainless steel mounting points.
•Powder-coated stainless steel yoke brackets included with the four smaller models (W2-218, W2-228
and W2-2W8); and are available as optional accessory kits for larger models (W2-312, W2-112, W2-122
and W2-125).
•Optional internal 70V/100V autoformer available for the W2-218, W2-228, W2-2W8 and W2-312 for
constant voltage distributed systems.
•All models are available in black or white finish at no additional charge. Custom colors are available at a
nominal fee.

High-Pass Filters
We strongly recommend the use of an external, active high-pass filter to protect the cone drivers from
excessive low frequency excursion. Additionally, a high-pass filter will avoid wasting amplifier by attempting to
reproduce frequencies below the loudspeaker’s intended operating range. The recommended filter settings are
as follows:
Model High-Pass Filter
W2-218
70 Hz, 24db/octave
W2-228 60 Hz, 24db/octave
W2-2W8 60 Hz, 24db/octave
W2-312
55 Hz, 24db/octave
W2-112
50 Hz, 24db/octave
W2-122 45 Hz, 24db/octave
W2-125
30 Hz, 24db/octave
Many modern DSP loudspeaker controllers or loudspeaker management devices can provide the required high-
pass filter mentioned above, as well as general equalization to correct for room response problems, digital
delay to correct for timing differences among multiple loudspeakers, as well as other DSP ‘tools’ that can help
solve acoustic anomalies. Such devices can also be used as protective peak limiters to protect the system from
damage, as further described below.

W SERIES W2 - Operation and Installation Manual - Page 9
Connecting the Amplifier to the Loudspeaker
All W2 loudspeakers come with an attached input cable that is coated with an EPDM rubber jacket, twelve feet
in length and colored to match the finish of the enclosure. The cable enters the enclosure through a waterproof
gland nut. The other end of the cable is un-terminated.
A typical installation method is to bring the cable into a waterproof Junction Box equipped with a waterproof
gland nut. Connections within the J-Box may be made with barrel-type crimp connectors, wire nuts, solder and
heat-shrink, or terminal strips. We recommend using barrel-type crimp connectors that are crimped with a
forged crimp tool (such as Klein 1005) or a ratcheting tool (such as Klein T1720), as this method, when properly
executed, results in a gas-tight connection that is quick and easy to accomplish.
DANGER: When wiring the amplifier(s) to the loudspeaker(s), always power-down the amplifier(s) and
disconnect its AC Mains plug(s). Many modern, high-power amplifiers can deliver enough voltage and
current to cause a harmful or lethal electric shock. Shocks from very low frequencies, such as kick
drums, can cause the human heart to stop beating at relatively low voltage levels.
WARNING: After wiring the amplifier(s) to the loudspeaker(s), first power-up all devices that are
upstream of the amplifier, such as mixers, equalizers, compressor/limiters, etc., before powering-up
the amplifier. This is to avoid passing any clicks or pops that may originate in the upstream devices to
the loudspeakers. The amplifier should initially be powered-up with its gain controls turned all the way
down. After making sure that a continuous signal is present, such as a CD playing, slowly raise the level
of the gain controls to establish that the wiring has been installed correctly. Only then should the
loudspeaker be operated at normal output levels.
IMPEDANCE AND COMBINING LOUDSPEAKERS
Loudspeakers of identical type may be wired together on the same amplifier. This forms a parallel circuit. When
two loudspeakers are wired in parallel, the nominal impedance of the circuit will divide in half. For example, if
two 8 ohm loudspeakers are wired in parallel, the result will be a 4 ohm load and the power from the amplifier
will be divided equally between both. If four 8 ohm (or two 4 ohm) loudspeakers are wired in parallel, the result
will be a 2 ohm load and again, the power will be divided equally among the loudspeakers.
If an uneven number of loudspeakers are wired in parallel, you can use the following formula to calculate the
resultant impedance, where Z is the impedance in ohms: 1/Z + 1/Z +1/Z = 1/Zt = Z.
Here is an example: 1/8 + 1/8 + 1/8 = 1/.375 = 2.666 ohms.
UNEQUAL IMPEDANCES
It is important to note that when wiring loudspeakers of unequal impedances in a parallel circuit, the power will
not be divided equally among each loudspeaker.
For example, if an 8 ohm and a 4 ohm loudspeaker are wired in parallel the resultant load will be 2.6 ohms. The
4 ohm loudspeaker will draw twice as much power from the amplifier than the 8 ohm loudspeaker. In this
example, if the amplifier is capable of producing 1800 watts into the 2.6 ohm load of the paralleled
loudspeakers, the 4 ohm loudspeaker will receive 1183 watts while the 8 ohm loudspeaker receives 591 watts.
KNOW YOUR AMPLIFIER
Not all amplifiers can safely drive loads below 4 ohms. Very low impedance loads may cause the amplifier to
overheat which may lead to device failure. Even if the amplifier is quite stable driving a low impedance load, the
cable loss will be greater, the damping factor is reduced, and if the amplifier were to fail, a larger portion of the
sound system would be taken off-line. Note: Keeping the loads at 4 ohms or higher will lengthen the life of your
amplifier(s), while improving the reliability and overall sound quality of your sound system.

W SERIES W2 - Operation and Installation Manual - Page 10
70V and 100V Operation
USING POWER TAPS
A W2 loudspeaker equipped with an optional autoformer has four selectable power taps. These are set at 12.5W,
25W, 50W and 100W on the W2-218, and at 25W, 50W, 100W and 200W on the W2-228, the W2-2W8, and the
W2-312 for 70V systems (note: for 100V systems the taps equal twice the numeric value stated above; i.e. a 25W
tap becomes a 50W tap, and so on). Note that the autoformer has a maximum output capability of 200W
regardless of the primary voltage.
By choosing one of the four taps, you can govern how much amplifier power is available for each loudspeaker.
For example, if the 50W tap is selected, that particular loudspeaker will draw 50 watts of power when a 70V
amplifier is run at its maximum level. A second loudspeaker might be connected to the same amplifier, but
tapped at 100W (100 watts). In such case, the second loudspeaker will draw 100 watts from the same amplifier,
making it 3dB louder than the first loudspeaker. A third loudspeaker might be tapped at 200 watts, which would
make it 3dB louder than the second loudspeaker, and 6dB louder than the first.
By using the various taps, one can balance the relative sound levels in a system. A loudspeaker that is closer to
audience members will need to be tapped at a lower wattage than one that is farther away, in order to produce
similar output levels (of course, the amplifier must be capable of delivering output power that is at least equal
to the sum of the taps).
As a guideline, every time you double the distance from a sound source, the level typically will drop by 6 dB,
which is equivalent to one-fourth of the power. Although this is an acoustical law, and is true in a free space
environment such as outdoors, the effect of room acoustics can radically change the actual results. Even
outdoors, it is normally not possible to validate this acoustical law using a sound level meter, due to the ground
plane effect.
70.7V AND 100V SYSTEMS
Several voltage standards have been put in place regarding so called ‘constant voltage systems.’ In the United
States, 25V, 70.7V and 100V are common. Occasionally 140V systems can be found, usually in very large venues
such as racetracks, where the need to overcome cable resistance by scaling the voltage upwards becomes
extremely important, due to the very long cable lengths from the amplifiers to the loudspeakers. In Europe and
Asia, most constant voltage systems use the 100V standard.
A W2 loudspeaker equipped with an optional autoformer supports both the 70.7V and 100V standards. The same
physical conductors are used for both voltage standards, but the power level of each tap is different, depending
on whether the voltage is 70.7V or 100V.
A 100V system will produce twice the power at a given tap, as that of a system that is operated at 70.7 volts.
This can be verified by the simple Ohm’s Law calculation E2/Z = W, where E is the voltage applied, Z is the load
impedance, and W is the power expressed in Watts. Assuming a load impedance of 50 ohms, we can see that
70.7 x 70.7 / 50 = 99.97 and that 100 x 100 / 50 = 200. Therefore, when scaling up from 70.7V to 100V the power
will double; when scaling down, the power will halve.
CAUTION: Be sure to carefully observe polarity when wiring your loudspeakers. If one loudspeaker is
wired with the opposite polarity from another loudspeaker, acoustic cancellation will occur. The result
will be less power output than if only one loudspeaker were used by itself.

SELECTING AMPLIFIERS
Amplifiers are a vital part of the sound system’s performance and should be carefully selected for appropriate
power output. A table is provided below to help you size your amplifier’s power output capability to the various
models in the W2 product line.
Typically, it is good practice to select an amplifier that can provide substantially more power than the
continuous rating of the loudspeaker. This is so that enough reserve power will be available for transient peaks.
More loudspeakers are damaged by under-powering them than by over-powering.
If you know in advance that a particular loudspeaker, or zone of loudspeakers will never be used at, or near their
maximum rated power, then it is acceptable to select a power amplifier that is equal to, or slightly larger than
the loudspeaker’s power handling specification. We do not recommend operating W2 loudspeakers with an
amplifier that does not at least meet the rated power handling of each model.

Note: “WRMS” = “Watts RMS” = “Watts Root Mean Squared”
AMPLIFIERS FOR 70V/100V OPERATION
In past times, nearly all 70V/100V amplifiers were of modest power level and employed step-up transformers
to increase their output voltage to a fixed value of 70V (or 100V) at their maximum operating level. The purpose
of stepping up the output voltage is largely to decrease the wire size needed for a given system, particularly
when long wire runs are unavoidable. A basic rule of Ohm’s Law is that the higher the voltage and the higher the
load impedance, the less effect the cable resistance has on the absorption of power within the cable. A
70V/100V system achieves both of these desirable design goals.
A second important reason for constant voltage systems is that the use of a step-down transformer at each
loudspeaker (or in the case of W2 products… a step-down autoformer) permits the installer to choose among
several power taps at each individual loudspeaker location. This lets the installer adjust each loudspeaker’s
level in relation to the other loudspeakers, even though multiple loudspeakers are driven by the same amplifier
on the same circuit. Without a transformer (or an autoformer), level adjustment could only be accomplished by
adding resistance to one or more loudspeakers. Resistors would in fact reduce the operating level, but would
also consume valuable power from the amplifier, as well as produce unnecessary heat as a byproduct.

W SERIES W2 - Operation and Installation Manual - Page 13
AUTOFORMERS
Autoformers, or autotransformers as they are often called, perform similarly to transformers but with certain
distinct advantages. First, they exhibit inherently lower distortion and lower insertion loss than an equivalent
rated transformer. Second, they are less prone to magnetic core saturation than a transformer, providing better
linearity under peak operating conditions. Lastly, they can be manufactured to a greater level of precision than
that of a transformer at a similar or lower cost. For these reasons, W2 loudspeakers have been designed to use
autoformers rather than transformers, when equipped for 70.7V/100V constant voltage applications.
Installation Considerations
Installing W2 loudspeakers is simple and straightforward. In most cases, they will simply be affixed to a wall or
ceiling surface by means of the stainless steel yoke-style mounting bracket that accompanies the four smaller
models, and is available as an optional accessory to the larger models. Always pay close attention to the type of
fasteners used, the nature of the mounting surface(s), and the suitability of the mounting method.
CAUTION! If there is any doubt as to the structural integrity of the mounting surface(s) and/or the
nature and use of the fasteners or other mounting materials, means, or method(s), consult a licensed
professional engineer who can provide accurate information that will assure a safe and reliable
installation. The potential for injury and/or death resulting from improper installation practices and/or
inadequate materials is very high. Please read the section on Safe Rigging Practices for additional
information, found elsewhere in this manual.
Note: When installing W2 loudspeakers, particularly the larger models, it is helpful to wear a pair of
heavy-duty industrial grade rubber gloves. The glass surface material and the unique curved shape of
the enclosures can otherwise be difficult to handle.
INSTALLING WITH YOKES
When attaching a yoke bracket to a W2 loudspeaker, always make sure to use the rubber washers (supplied).
They are intended to be placed between the yoke and the loudspeaker enclosure. They provide a seal to inhibit
the penetration of water into the enclosure, as well as increase the friction between the enclosure and the yoke
assembly. The bolts should be fitted with a lock washer and a flat washer (supplied), and tightened to a torque
of approximately 8 to 12 foot lbs. Be cautious, as overtightening can cause deformation or damage to the
fiberglass enclosure. Use a torque wrench!
IMPORTANT! Make sure that all rigging and mounting fittings have bolts, lock washers, flat washers and
rubber washers installed before completing the installation. No rigging or mounting fitting should be
left open to the elements.

W SERIES W2 - Operation and Installation Manual - Page 14
Rigging and Mounting W2 Enclosures
One of the most important tasks the installer faces is the rigging and mounting of the loudspeaker system. W2
loudspeakers have been designed with rigging and mounting in mind; thus, there are numerous ways to safely
and easily install these loudspeakers in optimal locations in a venue.
SAFETY FIRST!
There is no way to overemphasize the importance of safety. But we will try. The kinetic energy of an 80 lb.
loudspeaker enclosure dropping from 30 feet and contacting a concrete floor is enormous. The loudspeaker will
be traveling at a speed of about 35 MPH at the time of impact. Imagine if you were seated under it. You might
have a better chance of surviving a dynamite blast.
If you do not have knowledge of safe rigging practices and experience in applying them, contact a qualified
rigging contractor to design and carry out the installation! Rigging that is improperly installed is like a time
bomb; sooner or later it will fail, with the potential to cause serious injury, paralysis, dismemberment, or loss of
life. Even if no one is directly in the line-of-fall of a failed suspension system, the panic that might ensue could
in itself cause multiple deaths. Do not take chances!
RIGGING GUIDELINES
The following guidelines on rigging are not intended as a comprehensive rigging manual, nor are they meant to
replace the knowledge of safe rigging practices that might be obtained from receiving professional training on
the subject. These guidelines are intended only to provide basic safety information, and to call your attention to
some commonly made mistakes. Books, seminars, and hands-on courses are available that teach safe rigging
techniques; we highly recommend that you seek them out if you do not already possess the requisite knowledge
and experience to perform rigging work safely.
DISCLAIMER: Community warrants that its loudspeaker systems and its optional mounting and rigging
hardware have been carefully designed and tested. Community loudspeakers may be safely mounted and
rigged when each loudspeaker model is installed with Community-manufactured optional mounting and rigging
brackets specifically designed for use with that particular model of loudspeaker. This warranty applies only for
use under normal environmental conditions,3and when all loudspeakers, component parts, brackets and
hardware are assembled and installed in strict accordance with Community’s installation guidelines contained
herein. Beyond this, Community assumes no further or extended responsibility or liability, in any way or by any
means whatsoever. It is the responsibility of the installer to insure that safe installation practices are followed,
and that such practices are in accordance with any and all local, state, federal, or other, codes, conditions, and
regulations that may apply to, or govern the practice of, rigging, mounting, and construction work in the relevant
geographic territory. Any modifications made to any parts or materials manufactured or supplied by Community
shall immediately void all pledges of warranty or surety, related in any way to the safe use of those parts and
materials.
Load Rated Components
All components of the rigging system such as wire rope, shackles, chain, eyebolts, etc., must be load rated. This
means that they are marked or rated with a Safe Working Load (SWL) or Working Load Limit (WLL). All such
items should be designed and manufactured by reputable companies that regularly supply the theatrical and
industrial rigging industries, such as The Crosby Group, or equivalent. It is strongly recommended that you
source your rigging items from an industrial supplier or specialty rigging house, never from a hardware store.
Items found in local hardware stores are often poor copies of the original designs and may not be safe, as well
as typically being more costly than items purchased from an industrial supplier. By planning ahead, you will not
be in the uncomfortable position of having to delay the work if you can’t locate a shackle or eyebolt at the last
minute.
3Normal Environmental Conditions are defined as the following: -15 to 55º C, no excessive or unusual air-born contaminants or pollutants
present, no chemicals or contaminants coming in direct contact with the product, no excessive vibration or wind loads.

W SERIES W2 - Operation and Installation Manual - Page 15
Safety Factor
No component in a rigging system should be stressed to its maximum load rating. A suitable Safety Factor or
Design Factor must be determined and applied, so that every component in the rigging system has reserve load
capacity. The manufacturer’s stated SWL or WLL is the quotient of the component’s ultimate strength, or
breaking point, divided by the manufacturer’s stated safety factor. If the safety factor is not stated on the
component or in the manufacturer’s technical specification sheet, the component should not be used, as its
ultimate strength is unknown.
In addition to the manufacturer’s rated Safety Factor, the prudent installer will determine and apply an
additional Safety Factor to insure that the suspension system is installed in a manner that cannot fail under the
prevailing conditions.
Safety factors may be regulated by local, state, federal or international agencies and therefore may vary based
on your geographic location. Safety factors typically assume normal environmental conditions; additional
consideration must be given when unusual conditions are encountered, such as in corrosive marine
environments (e.g. loudspeakers mounted on a cruise ship or in a venue located near sea water), or in
conditions involving high-vibration, high wind-loads, or other unusual conditions. A common safety factor is a
6:1 ratio; however many theatrical rigging companies voluntarily work at a 7:1 ratio or higher. A 10:1 ratio is
required in most countries that are members of the European Union. At 10:1, this means that a component rated
at 10,000 lbs of ultimate strength should never be subjected to a load greater than 1,000 lbs. The de-rated value
of 1,000 lbs should take into account the additional force of dynamic loading, such as when a motorized hoist
starts and stops. Such dynamic loading can easily exceed 200% of the static load and is dependent on the hoist
design, how close to capacity it is loaded, the length of the cable or chain, and the elasticity of the supporting
structure.
Seismic Considerations
Seismic events (earthquakes) can cause great dynamic loading of a rigging system. In the case of strong quakes,
which occur regularly in some regions, a rigged system may merely sway back and forth with no damage, or it
may be subjected to many times its static load rating, particularly in the case of unequal loading of a multi-part
suspension system due to uneven roof or beam movement. It is also possible that one loudspeaker rig may
contact another rig or a lighting truss, during the quake. The results cannot be predicted because seismic events
occur with differing forms of wave motion at varying axes to the suspended system. An earthquake might
produce long, rolling waves in one axis then later, an aftershock on the same day could produce short, violent
waves in another axis.
Aging of Components
Over time, rigging components will degrade causing them to lose some, or even much, of their load capacity.
Factors include strain, oxidation, exposure to corrosive or acidic atmospheric conditions, exposure to water and
chemicals, exposure to UV light, and metal fatigue. In consideration of long-term durability, a high safety factor
should always be chosen, particularly when future conditions cannot be clearly foreseen (which is usually the
case).
Safety Cable
Safety cables must be sized appropriately for the loads they will carry, and should be attached to a different
point or points on the wall, ceiling, truss, frame, bumper, or other, than that of the primary suspension system,
as well as to a different point or points on the objects that are suspended.
Threaded Fasteners
Threaded fasteners are often used in rigging and mounting systems. As with eyebolts, many of Community’s
optional mounting brackets, yokes, and rigging plates utilize threaded fasteners. The fasteners that come with
each Community rigging kit are load rated to a sufficient strength to be safe when used within their specified
parameters. If replacement bolts are needed, or if additional bolts are required for mounting a bracket to a

W SERIES W2 - Operation and Installation Manual - Page 16
beam, wall, or ceiling etc., such bolts should be purchased from a reputable manufacturer with a minimum
Grade 5 rating. On hex-head bolts, this can be readily identified by looking at the head. A Grade 5 bolt will be
marked with three lines; a Grade 8 bolt, which is even stronger, with six lines. Allen drive fasteners are often
made of high-strength steel (Grade 5 or better) if they are purchased from an industrial suppler. As with any
other rigging component, check the rating on the box or the manufacturer’s specification sheet to be sure.
Support Points & General Practices
A vital part of planning the mounting or suspension system is to first determine the strength of the building’s
support points. Nothing should be assumed, even for the lightest loads. A ten pound loudspeaker falling from
ten feet can maim or kill just as readily as a heavy loudspeaker array falling from thirty feet. The services of a
registered structural or professional engineer should be employed to determine if the materials and design of
the supporting structure are adequate to support the intended load, and how to best install mounting brackets
or derive suspension points.
Fasteners
As a general rule, lag bolts driven into wooden beams should be avoided whenever possible, as they can pull out
as the wood ages or swells due to changes in temperature and humidity. Safe riggers will instead utilize
machine bolts of Grade 5 ratings or higher, rated beam clamps, brackets fabricated and welded by certified
welders, wire rope wrapped around beams with cushioning materials, and so on.
Certain wooden beams, or trusses, made of many laminations (often called Glue Lams) are intolerant of holes.
These beams are commonly used in modern construction, particularly in tilt-up concrete industrial buildings.
Drilling a hole through such beams can set up internal fractures, resulting in total failure of the beam.
Alternatives to drilling include fabricating steel brackets to surround the beam, or wrapping the beam with a
steel sling and fabric cushions, to derive a hang point.
Concrete expansion bolts, such as Hilti Kwik-bolts or equivalent, can provide an excellent means of attaching
moderate loads to concrete surfaces. However, as they rely on an expanding wedge to obtain their strength,
they must always be used in strict accordance with the manufacturer’s instructions. Such instructions specify
the diameter and depth of the hole, the composition of the concrete, permissible spacing of the anchors, and the
torque of the bolts. As a general rule, they should only be used for sheer loads, not tension loads.
Liability
When you install a loudspeaker that is mounted or suspended over people’s heads, it is your responsibility and
yours alone to insure that the installation is performed in a safe manner. Never take the word of someone who
tells you, “That beam is safe to drill into,” or “This point can handle the load,” or “I’ll take responsibility if
anything happens.” To paraphrase Harry Donovan from his excellent book on safe rigging practices entitled
Entertainment Rigging, ‘How is it going to sound to the jury at your manslaughter trial when you use such
statements by others as your defense?’
Never do anything you are not 100% sure is safe. If a manufactured product looks poorly designed and built, it
probably is poorly designed and built. If you are not absolutely sure where the wire rope came from or how
strong it is, don’t touch it. If the bolt looks too flimsy to hold the load, it probably is too flimsy. Always use your
best judgment, just as you do when driving at high speeds in traffic. The life you save may be your own, or that
of your friend or colleague.

W2 MOUNTING YOKES AND MOUNTING KITS
W2-218, W2-228 AND W2-2W8 YOKE ASSEMBLY
The compact W2-218, W2-228 and W2-2W8 loudspeakers include a yoke mounting bracket, constructed of 304
stainless steel finished in black or white with Community’s proprietary dual-layer powder coating process. The
yoke bracket is fitted with a series of mounting holes that allow the installer to vary the distance from the
enclosure to the mounting surface in order to suit the requirements of the installation. It is engineered to
provide a high margin of safety when supporting the appropriate loudspeaker.
All hardware required to attach the mounting yoke to the loudspeaker enclosure is included. No additional
hardware is provided to attach the yoke bracket to the mounting surface. Such hardware must be supplied by
the installer and should be sized and rated for the weight load of the enclosure, keeping in mind that additional
torque load may occur when focusing the loudspeaker within the yoke assembly. The installer is solely
responsible for determining if the mounting surface is capable of safely supporting the weight load of the
loudspeaker and bracket, and for selecting appropriate hardware to install it.
DANGER: All rigging fittings must be fitted with either optional mounting hardware or they must remain
sealed with the fasteners that come installed in the enclosure. These fasteners attach to internal steel
rigging brackets, thereby providing structural integrity. Without these fasteners, the structural integrity
of the enclosure would rely solely on the enclosure material and bonded joints, which over time could
deteriorate. Therefore, all rigging fittings must have fasteners in place so that the enclosure may be
safely ‘flown’ or suspended overhead.
Additionally, if the rigging fittings are not sealed, air leaks will occur in the enclosure that will
compromise the low frequency performance with distortion and reduced output.
WARNING: W2 loudspeaker rigging fittings are rated at a Working Load Limit of 150 lbs (68 kg) with a 15:1
safety margin. No single rigging fitting should ever be subjected to a load that is greater than 150 lbs.
Failure to heed this warning could result in injury or death!

SSY25KIT Mounting Kit for W2-112 and W2-312
An optional mounting bracket kit (model SSY25KIT) is available for the W2-112 and W2-312 loudspeakers. It is
sold separately. The SSY25KIT is designed to mount a W2-112 or W2-312 loudspeaker in either a vertical or
horizontal orientation, providing precise acoustic focusing. The SSY25KIT consists of a yoke mounting bracket
and two adapter plates, constructed of powder-coated stainless steel.
The yoke bracket is fitted with a series of mounting holes that allow the installer to vary the distance from the
enclosure to the mounting surface in order to suit the requirements of the installation. It is engineered to
provide a high margin of safety when supporting a W2-112 or W2-312 loudspeaker.
All hardware required to attach the SSY25KIT to the loudspeaker enclosure is included in the kit. No additional
hardware is provided to attach the yoke bracket to the mounting surface. Such hardware must be supplied by
the installer and should be sized and rated for the weight load of the enclosure, keeping in mind that additional
torque load may occur when focusing the loudspeaker within the yoke assembly. The installer is solely
responsible for determining if the mounting surface is capable of safely supporting the weight load of the
loudspeaker and bracket, and for selecting appropriate hardware to install it.
