COMMUNITY W SERIES WET II
OPERATION AND INSTALLATION MANUAL
INTRODUCTION
Thank you for selecting Community’s W SERIES WET II 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.
WET II 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.
WET II Loudspeaker Systems from Community
The upgraded WET II from Community combines all of WET’s original weather-defying characteristics with
improved styling and technology. WET II is 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. Some of our unique materials include:
Carbon Fiber. Used for LF and MF cones, carbon fiber exhibits a superior strength-to-mass ratio (high
Young’s Modulus [E]), over that of traditional cone material, thus improving transient response and
efficiency while simultaneously lowering distortion.
Polyimide. Used for HF diaphragms due to its excellent flexural strength and low resonance; quite unlike
brittle metallic diaphragms.
Fiberglass. All enclosures and horns are constructed of hand-laid fiberglass. Fiberglass is inherently
weather-resistant while exhibiting the strength, stiffness, and non-resonant characteristics needed to
insure an acoustically inert loudspeaker enclosure.
Stainless Steel. All hardware and fasteners, wherever possible, are made of stainless steel, highly resistant
to corrosion and oxidation.
Weather-Stop™ Grille. Each enclosure is fitted with Community’s proprietary Weather-Stop protective
grille. The grille consists of an outer layer of perforated steel finished with Community’s proprietary dual-
layer powder coating process, a center later of reticulated foam, and an inner layer of fine mesh screen
made from a rustproof UV-resistant synthetic material. This grille assembly prevents water intrusion, while
providing a high degree of acoustic transparency.
Ferrofluid. Most LF, MF & HF drivers use Ferrofluid in their voice coil gaps. Ferrofluid provides improved
heat transfer resulting in higher power handling, reduced distortion from fluidic dampening of mechanical
resonance, and it seals the air gaps against corrosion and oxidation.
Input Cables. WET II uses type SJOW neoprene jacketed cables rated for outdoor use.

Community WET II - Operation and Installation Manual - Page 7
These materials provide the absolute best in sound quality, appearance, and longevity.
WET II products offer a wide range of power levels, frequency response capability, and directional pattern
control. The WET II product line consists of a basic complement of six sizes of loudspeaker enclosures with
multiple dispersion patterns available in three of the 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 W2-215 two-way, 15” full-range system
The W2-312 three-way, 12” full-range system
The W2-322L three-way, dual 12” full-range system
The W2-315 three-way, 15” full-range system
The W2-112 single 12” subwoofer system
The W2-122 dual 12” subwoofer system
The W2-125 dual 15” subwoofer system
WET II features greater precision and tighter tolerance fit. Frequency dividing networks have been fine-
tuned for improved acoustical linearity. Plus, a newly developed 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 WET II makes them suitable for many
indoor applications as well. All WET II systems are available in standard black or white fiberglass finishes,
with an enclosure-matching black or white stainless steel grille finished with Community’s proprietary dual-
layer powder coating process. White WET II 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 WET II models
W2-218, W2-228 and W2-2W8, while optional mounting accessories are available for the larger full-range
and subwoofer systems. WET II is protected by a five-year product warranty plus a fifteen-year enclosure
warranty. WET II 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 WET II loudspeakers safely and effectively. It provides
useful information to help you obtain the best performance, sound quality, and reliability from your WET II
systems. We’ve 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

Introduction to Weather-Resistant Loudspeakers
Weather-resistant is a relative term that implies a loudspeaker’s ability to resist the effects of weather in
outdoor environments. Loudspeakers have been designed to be weather-resistant with varying degrees of
success. Typical weather-related damage problems encountered in such designs, in general order of
significance, concern the enclosure, drivers, hardware, and internal components such as crossovers.
WET II loudspeakers have been designed to be highly weather-resistant. WET II 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.
Unpacking and Inspection
WET II loudspeakers are inherently rugged and are carefully packed in well designed cartons. However, it’s
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 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)
Operation and Installation Manual (Qty 1)
Warranty Card (Qty 1)
Mounting Yoke for W2-218, W2-228 and W2-2W8 models only (Qty 1)

Community WET II - Operation and Installation Manual - Page 10
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: WET II 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!
WET II FEATURES AND TECHNOLOGY
In addition to extreme weather-resistance, WET II 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); available as an optional accessory kit for the W2-312 and W2-112.
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.

GENERAL DESCRIPTION
WET II loudspeakers are designed for top-of-the-line installation work. Their premium components are
housed in rugged, uniquely shaped curved enclosures that are acoustically inert. WET II systems are
characterized by high power and low distortion, with exceptional musicality and speech intelligibility.
The WET II line comprises six form-factors, three of which may be ordered with a choice of horn patterns.
The four smaller models may be ordered with an internal 70V/100V autoformer for constant voltage
applications, and all models are available in either a black or white finish. Custom colors are also available;
prices will be quoted upon request. Three models of WET II subwoofers round out the line, providing
extended bass response for foreground music applications.
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
W2-215 50 Hz, 24db/octave
W2-312 55 Hz, 24db/octave
W2-322L 40 Hz, 24db/octave
W2-315 60 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.

Community WET II - Operation and Installation Manual - Page 14
CONNECTING THE AMPLIFIER TO THE LOUDSPEAKER
All WET II 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’s 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.
C-TIP: 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.
Below is a table that gives a quick look at the effect of wire size on line loss. These numbers assume that
the amplifier is producing a constant 48 Volts at its output terminals, which is equivalent to 288 watts into
8Ω or 576 watts into 4Ω:
Size Length Load Z Loss in dB
#10 AWG 100’ 8 Ω-0.42 dB
#10 AWG 200’ 8 Ω-0.83 dB
#10 AWG 100’ 4 Ω-0.83 dB

70V AND 100V OPERATION
Using Power Taps
A WET II 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 WET II 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 WET II product line.
Typically, it’s 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’s 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 WET II
loudspeakers with an amplifier that does not at least meet the rated power handling of each model.

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 WET II 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.

AUTOFORMERS
Autoformers, or autotransformers as they’re 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, WET II
loudspeakers have been designed to use autoformers rather than transformers, when equipped for
70.7V/100V constant voltage applications.
