COMMUNITY PROFESSIONAL LOUDSPEAKERS
A TRADITION OF EXCELLENCE AND INNOVATION FOR OVER 30 YEARS
Before 1967, most sound reinforcement systems were made up of components designed for use in movie theaters.
Although these components worked well in theaters, the enclosures were large, bulky, heavy, and lacked output
capability in the critical midrange portion of the audio spectrum. This was very evident to a young audio engineer
named Bruce Howze, who was already involved in the fledgling touring sound industry, working with various rock
groups. He had a vision for a better way and, as a result, founded Community Light & Sound in 1967.
His concept was simple – design and build products that meet the needs of sound reinforcement with consistently
better products at a fair price. He also felt loudspeaker performance should be described in real-world terms.
Community is now well known as one of the only loudspeaker manufacturers to publish accurate, detailed, and
essentially raw performance data on its products using TEF™ measurements at realistic listening distances.
Community’s first product, dubbed the "LMF", was a fiberglass mid-bass horn for a 12 in. / 305 mm driver. It was
efficient, amazingly light, yet strong, making it ideal for touring use. Since then, Community has been distinctively
associated with fiberglass and with paying close attention to efficiency in converting electrical into acoustic energy.
Community continued to develop other unique products. The M4™ driver hit the market in 1981. This high power,
midrange compression driver covers the most critical portion of the audio spectrum – 200 Hz to 2000 Hz. This
removed the need for the usual crossover point right in the middle of the speech range. In keeping with not
designing “me too” products, the M4 diaphragm was made of thin aluminum skins sandwiching a structural foam
core – a fabrication technique still unique to Community. Recently the M4 has evolved with the development of a
nonpareil carbon fiber diaphragm virtually eliminating diaphragm failure. The M200™ midrange driver appeared 2
years after the M4 with an innovative diaphragm of aluminized mylar. Community has also demonstrated to the
world that big sound can come from small boxes, with the RS/VBS™ Series of electronically-controlled loudspeaker
systems that has now evolved into the Community Solutions™ series.
Most recently, Community has captured the audio world’s attention again with a number of innovative products: the
Leviathan II full-range horn system, the VHF100™ high frequency compression driver, the EM280™ and EM282™
extended midrange, carbon fiber diaphragm compression drivers. The EM282, M4, and VHF100 are the drivers used
in the revolutionary, forced-air cooled AirForce Concert System. With AirForce Community has, in a sense, come full
circle from the LMF, but this time with incomparable performance and hardware for a complete touring system.
Community’s History of Technological Firsts Include:
•First successful fiberglass MF / HF horns and giant fiberglass bass horns.
•First compression loaded midrange horn for touring systems – The LMF.

•First TEF/TDS documented loudspeaker line – RS/VBS.
•First 3-way cinema systems – Paramount Exec. Theatre, Warner Bros. screening theatre/dubbing rooms.
•First electro-acoustic system to equal the sound level of pneumatic warning sirens.
•First to provide loudspeakers for sound coverage of an entire country – Denmark Emergency System.
•First comprehensive calibrated testing of sound reinforcement products.

COMMUNITY XLT™ AND XLTE™ SERIES OWNER’S MANUAL
1INTRODUCTION
Welcome! You’ve joined the group of people that have chosen high quality Community loudspeaker systems and
components for over 30 years. We’re gratified you did and we will do our best to make sure you are satisfied with
your new loudspeaker system.
In order for you to get the most effective use of this product, please take some time to read this manual. If you are in
a hurry and can’t wait, you can use the QUICK START-UP diagrams to connect your loudspeakers and be operating
them in few minutes. However, we have included a great deal of other useful information in this manual that will
help you to realize the best performance, operation, sound quality, and reliability from your new loudspeaker.
1.1 COMMUNITY XLT AND XLTE SERIES LOUDSPEAKER SYSTEMS
This manual contains information for the proper setup and operation of the Community XLT and XLTE full-range
loudspeaker systems and subwoofers. While every attempt has been made to ensure this information is correct and
up to date, Community continuously incorporates worthwhile improvements to each product that may include
changes and/or modifications not contained in this manual.
1.2 MODEL NUMBER USAGE IN THIS MANUAL
Within this manual XLT and XLTE models are generally referred to only by their numerical suffixes. For example,
model ‘43’ refers to both the XLT43 and XLT43E. Where information applies only to a specific model, such as only to
the XLT46 but not the XLT46E, the complete model number is used.
1.3 IMPORTANT SAFETY INFORMATION
The terms “Caution,” “Warning,” and “Danger” are used throughout this manual to alert the reader to important
safety considerations. If you have any questions about any aspects of these cautions, contact your local dealer,
distributor, or Community.
CAUTION: describes an equipment 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
injure the user.
DANGER: describes an operating condition or user action that will immediately damage the equipment or be
extremely dangerous or possibly life-threatening to the user.

2 UNPACKING AND INSPECTION
The Community XLT and XLTE loudspeakers are inherently rugged and are carefully packed in well-designed cartons.
It is a good idea to inspect the unit carefully after it has been removed from the packaging, as sometimes there is
hidden damage due to some unfortunate incident in shipment.
Please note that once the shipment has left Community, the responsibility for damage is borne by the freight
company. This means that if there is damage, you must file a claim with the freight company. Each freight company
has its own set of regulations that must be followed and forms that must be filled out. Therefore, the freight
company must be contacted as soon as a shipping damage problem is discovered. Save the carton and packing
material because many damage claims will be considered invalid if these are thrown away. The Community dealer
and the factory will try to help in any way possible. Remember, though, it is up to the party receiving the shipment
to file a damage claim.
It is always a good idea to keep the carton and packing material in case the unit must be shipped back to your dealer
or distributor.
The shipping carton contains the following items:
(1) Loudspeaker system
(1) Owner’s manual
(1) Warranty card
(1) Feet Kit (XLT41E only)
