A TRADITION OF EXCELLENCE AND INNOVATION
Since the founding of our company in 1968, Community has been a constant developer and innovator of
loudspeaker technology. Many of our engineering achievements were undertaken to solve problems, when no
prior solutions existed. Others resulted from simply seeing a better way to do things.
Over the years our technologies have been imitated, and our methods have become common practice
throughout the professional sound industry. However, developments like carbon fiber diaphragm compression
drivers still stand alone, and well ahead of the competition. Just a few of Community’s unique accomplishments
include the following:
• First successful fiberglass mid, high frequency, and large-format bass horns.
• First compression loaded mid-range horn for touring systems - the LMF.
• First suspension-less diaphragm HF driver - the VHF100.
• First mid-range, full-decade (200 Hz - 2 kHz) high-power compression driver - the M4.
• First carbon fiber diaphragm compression drivers - M4, EM280, EM282.
• First Ferrofluid-cooled professional woofers - the VBS Series.
• First product series with all drivers Ferrofluid-cooled.
• First air-cooled loudspeakers for touring systems - AirForce.
• First three-way cinema loudspeaker systems - Paramount Executive Studio Theatre, Warner Bros.
screening theatre and dubbing rooms.
• First electro-acoustic system to equal the sound level of pneumatic warning sirens.
• First to provide loudspeaker coverage over an entire country - Denmark Emergency System.
• First comprehensive, calibrated data acquisition of sound reinforcement products.
• First integral signal-aligned three-way sound reinforcement systems - RS Series.
• First pro audio company with an Internet Web site.
• First all horn-loaded, high-fidelity, weather-resistant loudspeaker - R2 Series.
In line with our history of excellence and innovation, each Community product is manufactured in
accordance with a complicated and exacting chain of procedures that ensure absolute quality.
With our unique designs, our sophisticated techniques, and our proprietary materials and transducers,
we are committed to bringing only the finest audio products to the many thousands of professional sound
engineers, performers, and end users who rely on them daily.

IMPORTANT SAFETY INFORMATION
Always follow these safety precautions when using or installing ENTASYS loudspeakers and
accessories:
• Read and keep these instructions.
• Heed all warnings.
• Follow all instructions, particularly those pertaining to rigging, mounting, hanging, and electrical
connections.
• Only use accessories that are specified and approved by the manufacturer.
The terms IMPORTANT, WARNING, and DANGER, as used in this manual, alert the reader to
important safety considerations. If you have any questions or do not understand the meaning of these terms, do
not proceed with installation. Contact your local dealer, distributor, or call Community directly for assistance.
IMPORTANT: describes an operating condition or user action that may expose the equipment or user to
potential damage or danger.
WARNING: describes an operating condition or user action that will likely cause damage to the
equipment or injury to the user or to others in the vicinity.
DANGER: describes an operating condition or user action that will immediately damage the equipment
and/or be extremely dangerous or life threatening to the user or to others in the vicinity.
RIGGING AND ELECTRICAL SAFETY
DANGER: The loudspeakers described in this manual are designed and intended to be ‘flown’ or
suspended using a variety of rigging hardware, means, and methods. Installation of loudspeakers
should only be performed by trained and qualified personnel. It is strongly recommended that a licensed
and certified professional structural engineer approve the mounting design. Severe injury and/or loss of
life may occur if these products are improperly installed!
DANGER: All rigging fittings must be fully tightened and secured. Any missing fasteners will
compromise the structural integrity of the enclosure and constitute a safety hazard. Do not
suspend this loudspeaker unless all fasteners are securely in place!
IMPORTANT:Refer to the sections on installation and connections later in this manual for additional
information on rigging and electrical safety.
IMPORTANT SAFETY INFORMATION

Community ENTASYS Installation/Operation Manual — Page 7
UNPACKING AND INSPECTION
ENTASYS loudspeakers are inherently rugged and are carefully packed in sturdy cartons. However, it’s
wise to thoroughly inspect each unit after it has been removed from the packaging, as damage could occur
during shipping.
SHIPPING CLAIMS
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.

ELECTRICAL INSTALLATION AND SAFETY
Electrical Safety
DANGER: The output voltage and current capabilities of audio power amplifiers present a danger to
installers especially in 70-volt and 100-volt distributed systems. To minimize the risk of electric shock
from loudspeaker connecting cables, confirm that the power amplifiers are turned “off” before connecting
loudspeaker cable to the loudspeaker or amplifier.
Electrical Connections and Cabling
Input signal cabling for ENTASYS loudspeakers can be connected to either the NL4 connector, dual
banana jack, or the input terminal strip on the bottom of the loudspeaker. A weather-resistant cover can be
attached to protect the input connectors from moisture and debris. Two relief areas in the bottom end cap allow
for cable up to the size of 16-2 SJO with the cover in place. Larger cable can be accommodated via the knock
out in the cover. A 1/2 inch NPT conduit fitting can be secured to this knock out.
When stacking two ENTASYS loudspeakers together the input signal can easily pass from the bottom
loudspeaker to the top loudspeaker using the supplied Banana Plug Jumper. Insert this jumper into the Banana
Thru connector on the top of the lower loudspeaker. When the upper loudspeaker is placed on top of the lower
loudspeaker, the Banana Plug Jumper will fit into the Banana Input Jack of the upper loudspeaker. No other
connecting cable for the upper loudspeaker is required.
The top most ENTASYS in an array should have the included rubber plug inserted into the Banana Thru
relief at the top of the loudspeaker. This will prevent moisture or debris from entering this relief area. This
rubber plug should not be used for lower ENTASYS loudspeakers in an array.
Up to three ENTASYS Full-Range or ENTASYS Low Frequency loudspeakers can be electrically
connected in this manner and present the driving amplifier with a 4 ohm load.
See the Installation section for more information including high pass filters for ENTASYS. ENTASYS is
a passive only loudspeaker system and cannot be bi-amplified or tri-amplified.
* Also see Pages 38-39 for “Impedance” and “Recommended Amplifier Size”
Outdoor Installations—Minimum Downward Installation Angle
NOTE: Whenever ENTASYS column loudspeakers are installed outdoors, or exposed to direct rain,
water or precipitation, the loudspeaker enclosure must be angled downward at a minimum of two (2)
degrees.
