Professional Loudspeakers is expanding it's VLF Series of subwoofers. VLF218 is a high-efficiency, dual
18-inch subwoofer system with a slim profile and rugged Baltic birch-ply
enclosure. With power handling of 1,600W continuous (4,000W program)
and sensitivity of 106dB/W/m, it offers exceptional punch, high output
and low distortion. Additionally, the drivers may be configured
internally to be driven by a single amp (1,600W @ 4 ohms) or by dual
amplifiers (800W @ 8 ohms each).
The VLF218 uses a unique
combination of techniques to keep voice coil temperatures low to avoid
power compression that causes reduced output at higher volume levels.
Using a proprietary method known as Active-Air Cooling, the motor
structures of each driver are situated inside of the port where the
outside moving air actively removes heat from the assembly.
Additionally, cone movement drives air through the vented magnet
pole-piece to cool the motor structures further.
BCL (Balanced Cone Loading) improves the linearity of the system by
balancing the front and rear air loads. The thirdharmonic distortion at
40V (50-percent power) averages less than 1.9 percent over its operating
range, and the enclosure has strong internal bracing to reduce sound
energy losses from enclosure vibration.
Standard units are
fully outfitted with pocket lifting handles, corner "hand truck" bar
grip handles, tour-grade casters, top and bottom stacking cups, and
rubber feet. Standard available options include front and rear Seat
Track, pole sockets, custom colors, and Fiberglas-covered weatherized
The VLF218 is an efficient, dual 18 inch subwoofer that can be used with any full-range loudspeaker system. It has exceptional punch, high output, and low distortion. The VLF218 uses a unique combination of techniques to keep voice coil temperatures low to avoid power compression that causes reduced output at higher volume levels. Ferrofluid efficiently transfers heat from the 4 inch voice coils to the motor structures. Active-Air cooling uses the bass ports to move outside air over the motor structures of each driver. Additionally, cone movement drives air through the vented magnet pole-piece to cool the motor structures. BCL (Balanced Cone Loading) improves the linearity of the system by balancing the front and rear air loads. The 3rd harmonic distortion at 40V (50% power) averages less than 1.9% over its operating range. The enclosure has strong internal bracing reducing sound energy losses from enclosure vibration.

COMMUNITY, ett fint Amerikanskt märke som funnits i 50 år:
In the mid 1960s music was on the move. The growing "rock revolution," and the need to bring its explosion of new musical styles and messages to audiences around the world, demanded an evolution in the technology of touring sound: lightweight, mobile systems able to reproduce the depth and complexity of the music with absolute impact and clarity. Communication had become the critical factor in live sound.
Bruce Howze, a creatively inclined loudspeaker designer working in Pennsylvania with influential bands such as Jefferson Airplane, was keenly aware that 2-way sound systems based on equipment from movie theaters were no longer viable. These had unacceptable limitations in coverage, clarity, and portability, largely due to their massive size, weight, and the lack of midrange output of their loudspeakers, a result of their limited 2-way design.
The Fiberglass Revolution
Determined to solve these problems, Howze came up with an original idea that would revolutionize the technology of live sound. To improve the clarity and coverage of loudspeakers and reduce their weight, he designed and engineered lightweight horns and enclosures from fiberglass, a radically different material for that application. This breakthrough eventually led to the foundation of Community Light & Sound in 1968 and landmark products such as the LMF, a round compression-loaded fiberglass horn driven by a 12" cone that specifically addressed the lack of midrange output. The focus on the importance of the midrange frequencies and use of fiberglass immediately set Community apart from its competitors and became central to its ongoing legend.
Hand-shaping, custom molding and the hand-lamination of fiberglass materials require extra time, care, and attention to detail. This unique process gave the LMF and subsequent designs a significant weight advantage over wooden and die-cast metal horns. More importantly, the natural sound characteristics of the glass fiber composite, coupled with the LMF's precisely formed shape, produced an articulate, detailed sound with increased projection. It also eliminated gaps or "holes" in the midrange frequencies, allowing vocals to be clearly heard and understood.
A decade later, Community was growing into a family of creative audio professionals, a true "gathering of excellence" dedicated to applying new thinking and common sense solutions to live sound in all types of venues. Today, Community uses FRP composites, carbon fiber, polyethylene and other materials to create a wide range of all-weather, all-purpose loudspeakers that excel in any type of indoor or outdoor venue.
Refining Communication in Live Sound
Starting with Howze's ideas as the source, Community's innovations have produced industry-leading products such as the M4 midrange driver, known for its unmatched power and extremely low distortion. The M4 later became one of many Community midrange drivers to use carbon fiber for the diaphragm, a material that provides greater strength without the negative effects of commonly used metallic diaphragms.
One of Community's most unique and influential products, the M4 further refined the concept of a dedicated single component vocal range driver, bringing greater clarity and a natural, intimate sound to the vocals. Commenting on the M4, Howze has said, "People tend to think in terms of extending the bandwidth and getting more bottom, more top. They sort of miss the point that all the information is in the midrange and, if you don't get that right, the rest of it just doesn't mean anything."
Expanding beyond breakthrough efforts with vocal-range, horn-loaded products, Community has become known for a range of unique solutions that make sense. The company was the first to conceive of 3-, 4-, and 5-way loudspeaker system designs now used throughout the industry. This idea allowed us to optimize individual components and significantly reduce distortion in full-range system designs.
Over the years, Community has led the way in providing powerful and articulate full-range sound with exceptional "throw" (projection capability) in massive outdoor and indoor venues. We developed the world's first giant triaxial full-range, weather resistant horn system; the first compact, full-range weather resistant horn system; and the first high quality all-purpose, all-weather loudspeaker system, the WET Series. The design, construction, testing, and effective positioning of these systems allow our clients to not only reproduce audio more efficiently, but actually involve spectators and audience members in the total entertainment experience.
We've designed the clarity, balance and projection of our larger systems into a range of versatile theater and club systems so that musicians and DJs can effectively communicate their music and lyrics with maximum power, deep bass impact and an exceptional response throughout the midrange and upper frequencies. Our permanently installed loudspeaker systems bring new standards of clarity and coverage to schools, auditoriums, houses of worship, and other installations.
In addition to innovative ideas and designs, each of our products is manufactured as part of an exacting procedure to ensure absolute quality. The construction of a Community compression driver is a personalized process, with a number of intricate steps that must be executed by hand with care and precision. Time-consuming and costly, this process provides exceptional control over each component and results in absolute electrical and mechanical efficiency with no compromises in audio performance.
Testing: Our Commitment to Excellence
Scientific testing is integral to our legacy. Over the years, we've developed ways to test and document the spherical propagation characteristics of all loudspeakers; published the coverage patterns of our own loudspeakers; and introduced the industry's first electro-acoustic modeling software. Under the inspired guidance of vice president John Wiggins, Community was the first to apply sophisticated Time Delay Spectrometry (TDS) techniques to the development of signal-aligned loudspeaker systems. Now an accepted technology to maximize system effectiveness, this led to our Wavefront Coherent™ design, featured in Community's electronically-controlled system products.
Dedication to testing lets us evolve and develop entire families of products from proprietary manufacturing methods to produce effective designs that truly excel in a given application. The freedom to experiment with engineering solutions allows us to innovate and anticipate the needs of our growing customer base around the world.
Implementing the Future
Community manufactures most of its components and cabinetry in our modern 100,000 square foot Chester, Pennsylvania facility, near Philadelphia. Centrally located with easy access to transportation facilities, the plant reflects our ongoing commitment to improving and modernizing every facet of production. We've implemented ISO quality standards and acquired advanced computer-controlled precision milling, modeling, molding and production systems, all of which have contributed to a significant annual growth in recent years.
Deeply committed to Chester with a local workforce of dedicated individuals we've trained and developed, Community continues as a growing and diverse "family" of professionals whose commitment to excellence is central to our growth. We believe in an enlightened and responsive way of doing business in a work environment that encourages growth, opportunity, enjoyment, and mutual respect.
In addition to its wide range of loudspeaker systems, Community designs and manufactures proprietary transducers to ensure the excellence of our systems. We continue to allocate significant resources to this area to ensure our position as a leading worldwide producer of professional audio transducers.
Over the years, Community has been recognized by the Commonwealth of Pennsylvania with a series of special Governor's 1st Place Awards for Excellence in the Expansion of World Trade of Pennsylvania Exports Abroad; Environmental Excellence; and Outstanding Achievement in Export Sales. We've also won the President's "E" Certificate for Exports Award presented by the U.S. Secretary of Commerce.
But these and the numerous industry awards we've earned only enhances the fact that our loudspeaker systems are in the world's leading concert halls, theaters, arenas and stadia. World-class venues such as Atlanta's Georgia Dome, Ireland's Limerick University, Las Vegas' Mirage Casino, Orlando's Walt Disney World, Universal Studios, Warner Brothers Film Studios, and the White House in Washington, D.C., to name a few.
More recently, our equipment has been installed in landmark systems such as the Milwaukee Brewers' Miller Park, Denver's Invesco Mile High Field, and the Gaylord Palms Hotel Convention Center in Kissimmee, Florida. We've also developed special paging systems for the Cape Canaveral NASA Vertical Assembly Building, Space Vehicle Assembly Building, and Press Viewing Stands for the launches.
Community continues to do what we've become known for since Bruce Howze first founded the company. We start with unique and practical ideas designed to bring the highest level of communication to sound reproduction. These ideas then evolve into unique designs manufactured with rigorous and sophisticated techniques, coupled with new proprietary materials and transducers, to achieve superior standards of acoustic excellence. Beyond that, we constantly look for new ways to better develop and provide the finest audio reproduction technologies to the world marketplace.
