Community Completes New Loudspeaker Test Facility

Hadi Sumoro at Community's New Loudspeaker Test Facility RoomIn keeping with its commitment to accurate and complete loudspeaker technical data, Community has opened a new, state-of-the-art indoor test facility at its factory in Chester, Pennsylvania USA. Designed by Charlie Hughes of Excelsior Audio and operated by Senior Measurement Technician, Hadi Sumoro, the new test facility enables loudspeaker measurements with unprecedented accuracy and precision.

With its indoor location, the new facility makes it possible to control temperature and humidity. It eliminates wind problems and minimizes interference from outside noise sources. This allows Community engineers to accurately measure complex loudspeaker data and to gather polar data in precise 1-degree resolution. Measurements are automated with an ELF robotic rotator system controlled by EASERA™ software.

The new test facility follows in the footsteps of a long tradition of loudspeaker measurements at Community. Community’s first test facility was a 32-foot-high tower built in 1975 on a southeast Pennsylvania hilltop which provided measurements that closely corresponded to

anechoic chamber standards and established Community as an early leader in providing accurate loudspeaker specifications. In 1981, Community built a semi-anechoic room in its factory to manually collect spherical propagation data of loudspeakers using Time Delay Spectrometry (TDS) technology developed by Richard Heyser and Gerald Stanley. In 1994, Community built a new outdoor test facility extending from the third floor of its factory building in Chester. At 40 feet above the ground and with a microphone to loudspeaker distance of 39 feet, this system is still utilized today and uses TDS software to collect far-field and free-space data and to minimize outdoor noise and reflections. The outdoor test system provides the ability to measure low-frequency loudspeakers in near-free-space conditions.

Regarding the new test facility, Community’s Director of Technical Services, Dave Howden said, “Community’s outdoor measurement systems were an important resource for our TAG (Technical Applications Group) group as we worked with systems designers and end users. Now, this new indoor facility provides phase data and other new information for systems designers and will help Community’s engineering team design the next generation of great loudspeakers.”

Game Seven Grill Opens to Championship Sound

Game Seven Grill is a barbecue restaurant located in the Gila River Casinos Plaza at Chase Field, home of the Arizona Diamondbacks baseball team. With a name that evokes the D-Backs Championship victory in Game Seven of the 2001 World Series, Game Seven Grill’s casual atmosphere and family-friendly style are reflected in its interior design which builds on the brick and open-beam architecture of the building.

Before opening in March of 2013, Game Seven Grill underwent a major renovation including new seating, championship décor and a new sound and video system featuring Community CP6 pendant loudspeakers for the interior and R.25-94T loudspeakers for the Grill’s outdoor plaza seating.

Game Seven’s sound and video systems were designed and installed by Parsons Technologies of Phoenix, Arizona. Mark Schultz, Systems Engineer, designed the systems at Game Seven Grill. He says Parsons provides audio and video systems for many of the venues at Chase Field. “The team owns the Game Seven building,” Schultz said, “and they contacted us to design and install the sound and video systems for this new restaurant.”

Schultz knew that Game Seven would feature an open interior design with its ceiling painted black. The owners had asked for a great music and video system but they made it clear they wanted “invisible loudspeakers”. “Community’s Commercial Design Series CP6 pendants were the perfect choice,” said Schultz. “They sounded great and we could get them in black to disappear against the ceiling. We used Community’s R.25 loudspeakers for the outdoor plaza seating,” he continued. “They were also available in black and they sound great as well.”

Game Seven’s sound system is used for background music and for sports event play-by-play audio. The system is divided into two zones, indoor and outdoor. During a baseball game or other sporting event, the restaurant can choose to play the audio from a local radio or TV station into either zone so that patrons can watch and listen to the game. The audio system is powered by CTS amplifiers and features a BSS DSP system with touch-panel controls for volume and source selection.

“We did a little EQ but didn’t need much,” Schultz said. “And the owners are extremely pleased with the sound and appearance. We’re expecting them to expand the system to the upper level of the restaurant, which will be undergoing renovation prior to the 2014 season.”

Annapolis Summer Garden Theatre Performs with Community

Founded in 1966, Annapolis Summer Garden Theatre (ASGT) is an outdoor community theatre in Historic Downtown Annapolis, Maryland. With its all-volunteer staff and actors, ASGT hosts three major productions each season in an outdoor garden setting. While most ASGT productions are musicals, the venue also hosts Shakespeare, improv and educational programs.

The outdoor garden setting is pleasant for theatre goers, but it presents ongoing challenges to actors and staff ranging from lingering afternoon heat and inclement weather to noise from boat engines and horns at the nearby City Dock. Scott McCormick, one of two Technical Directors at ASGT, says the theatre’s previous loudspeakers weren’t weather-resistant and had to be bagged or removed from the theatre when it rained and after each performance. In addition, they had poor directional control which contributed to on-stage feedback issues and neighborhood noise complaints.

Last summer, McCormick and members of the tech team approached the board of directors with a request for a new loudspeaker system. He wanted to fly the system on a truss that could double as a lighting truss. He wanted high-performance loudspeakers that were weather-resistant and could be left in place throughout the year. And, he wanted good directional control to provide even coverage in the theatre and reduce sound levels in the neighborhood.

McCormick contacted David McLain of CCI Solutions who modeled the theatre and recommended weatherized Community iBOX model iHP-1226WR loudspeakers for left and right front-of-house, i-212SWR’s for subwoofers and WET W2-228 loudspeakers for stage/foldback monitors. The mains and subs are suspended from the truss at stage left and right and the monitors are suspended behind the mains to cover the stage while minimizing their visual impact.

The theatre uses Shure UHF wireless microphone systems with Countryman headsets. On a typical production, all actors are equipped with wireless. The system is powered by QSC amplifiers and uses a Community dSPEC226AN loudspeaker processor for equalization and loudspeaker management. McCormick says the Community dSPEC is a “joy to work with” and he especially loves the amplifier calibration feature. He plans to use dSPEC presets to set up differing equalization for weather and humidity changes.
McCormick says the modeling was very accurate so that coverage is consistent throughout the theatre and they no longer receive neighborhood complaints. When the system was first turned on, everyone loved the sound. “Their jaws dropped,” said McCormick. “Everyone in the theatre can hear clearly and this year’s reviews are all positive about the sound.” He also noted that the stage monitor coverage was greatly improved while feedback was virtually eliminated. One actor commented, “I’ve never been able to hear anything like this on this stage!”

Community Provides Audio Quality and Reliability for Poland’s Mielec Stadium

Tommex Zebrowscy Sp. J. has completed the design and installation of a Community loudspeaker based audio system for the new multi-use Mielec Stadium, in Southeast Poland.
Home to the Stal Mielec football (soccer) team, the new stadium replaces the original which was built in 1953 and hosted numerous high-profile events like the European Champions Cup, UEFA Cup, and Polish national team matches, including FIFA World Cup and UEFA European Championship qualifiers. While providing a completely modern venue, the new stadium replicates the old venue’s seating capacity of 30,000 and its format of an athletics track around the playing field to provide multi-sport facilities.
Two tiered stands flank the length of the stadium, with the main West stand also providing for 100m athletic events. The system designed by Tommex comprises twelve Community R.5HPT three-way, horn-loaded coaxial loudspeakers covering the seating areas of the West stand, with a mirrored system of twelve Community R.5HPTs covering the East stand. Two R2-52 three-way, horn-loaded triaxial loudspeakers are also mounted on the West stand canopy, to cover the pitch and competition zones. Additionally, Tommex provided sound projector and ceiling loudspeakers for the public areas and the rooms under the stands.

Tommex chose Dynacord DSA 8410 and PCL 1240T amplifiers to drive the systems, located in two separate amp rooms in the West and East stands. System integrity is ensured with the use of Dynacord’s DCS (Digital Control Switching) system to provide uninterrupted transmission in the event of any amplifier failure.

Mixing is provided by a Dynacord CMS 1000-3 and a Dynacord P 64 controls the matrix and signal processing, with system monitoring. A computer with touch screen is connected to the matrix P64 to provide a convenient interface for independently adjusting sound levels in the stands, on the pitch and in the zones under the stands.

Jarosław Kraszewski of Tommex, the designer and project manager for the system, explained, “We have successfully completed many projects of this type and always get great results using Community R-Series. Their audio quality, high intelligibility and efficiency set the standard that stadia expect today and their all-weather capability and long-term reliability is a major factor that we know we can depend on.”

Community Helps “Horses with Hope” Rescue Horses

Broadview Farms, near Hope, Maine, is the home of “Horses with Hope,” an organization whose mission is to rescue and rehabilitate abused, neglected and abandoned horses and match them with compatible homes. In 2013, Horses with Hope completed a spacious new venue at Broadview Farms with an indoor riding arena, a viewing area, horse stalls and living quarters for staff and visitors.

Designed and built by “Houses and Barns by John Libby”, the facility includes an audio system designed to recreate the sounds from a commercial venue, such as a riding tournament, and to play music and provide communication for horse training.
General contractor Houses and Barns by John Libby retained AV Systems of Maine of Bowdoinham, Maine, to design and install the audio system. Owner Bill Wayman chose Community R-Series loudspeakers for the arena and Community D-Series ceiling loudspeakers for the viewing area, offices and other spaces.

“The arena is open to the outside,” said Wayman, “so I wanted loudspeakers that sounded good and could deal with the temperature and humidity extremes we have in Maine.” Wayman designed an array for the arena with four Community R1-94TZ loudspeakers equipped with 200-watt auto-transformers. He used a single R.5-99TZ for down-fill.
For the viewing area, offices and other spaces, Wayman designed a 70-volt distributed system with six pairs of Community model D6 ceiling loudspeakers.

The audio system uses an Ashly 8-channel power amplifier and an Ashly controller/processor. Wayman provided two wireless headset microphones to allow the riders and trainers to talk to visitors in the viewing areas. Trainers also use these microphones to communicate with riders. Users can select microphones, music or natural background sounds and control the system volume from a wall panel in each zone.

Wayman says the owners are very pleased with the sound quality and coverage of the audio system. “They agreed to have me install two additional zones after hearing the arena system,” he said.

Community Escalates Performance, Style and Musicality of R-Series with New “R-MAX” and Compact Models

Community Professional Loudspeakers has announced the introduction of eight new models to its premiere R-Series line, with new performance dimensions that expand the applications of this already comprehensive loudspeaker range. Three new compact models, the R.15COAX, R.35COAX, and R.35-3896, give systems designers increased flexibility by offering vastly improved music playback, additional coverage patterns and higher output in attractive paintable ABS enclosures. Five new R-MAX products, the R.5-66MAX, R.5-96MAX, R2-64MAX, R2-66MAX, and R2-94MAX, provide the most well behaved, flattest musical response, premium loudspeakers ever offered in the R-Series.

The R.15COAX and R.35COAX use identical 1.25-inch exit HF compression drivers, featuring Community’s exclusive Tru-Phase™ phase plug technology, and Carbon Ring Cone woofer technology which allows LF drivers to exhibit cone areas up to 20% larger than standard woofers of the same diameter. Both models feature front loaded LF drivers, 6.5-inch in the R.15COAX and 10-inch in the R.35COAX, in highly reinforced enclosures for natural, non-resonant low frequency reproduction, while identical voicing across both models ensures a uniform listening experience. The dynamic R.35-3896 is a triaxial 8-inch Carbon Ring Cone loudspeaker featuring Community’s exclusive MultiSource Waveguide™ technology, integrating the output from dual midrange compression drivers and a 1-inch exit HF compression driver into a single coherent source. Fully passive, it is voiced for flat musical reproduction without EQ and delivers class-leading SPL levels for a loudspeaker of its size.

“In addition to the great musical performance of these new compact models, the most obvious visual difference is the sleek new paintable ABS enclosure,” said Chris Barrow, Community’s Director of Product Marketing. “It is visually superior and offers more flexibility while costing less to produce. That allowed us to invest in better audio components for exceptional
performance without driving up the price.”

R-Series has always been acknowledged for its high output and voice intelligibility. Now, R-MAX also demonstrates the type of premium music performance that Community is capable of delivering. These loudspeakers can hold their ground against products costing two or three times as much. R-MAX are not just great outdoor loudspeakers, they are great loudspeakers period.” With the addition of the new R-Series models, Community provides systems designers and consultants with a new palette of features, while also improving core R-Series capabilities.

St. Joseph Fullerton Hosts Traditional and Contemporary Mass with Community

Founded in 1850 by German immigrants, St. Joseph Fullerton is a Roman Catholic church located just north of Baltimore in Perry Hall, Maryland. St. Joseph’s current building, an octagonal structure with around-the-sanctuary seating, and imaginative décor has impressed parishioners and visitors for more than 40 years.

St. Joseph’s original sound system used ceiling loudspeakers to cover the sanctuary and had been augmented with loudspeakers in the organ chamber. However, coverage was uneven in many locations and very poor in the back of the church.

Through a referral from another church, St. Joseph’s contacted Mike Flaherty of Nelson White Systems in Baltimore. Flaherty recommended a system based on Community’s Entasys column line arrays. He had used Entasys in other church sound systems and knew they would provide smooth coverage throughout the sanctuary and project sound evenly all the way to the rear while minimizing unwanted reflections from the ceiling and floor.

Flaherty chose left and right double-stacked Entasys to cover the central areas of the sanctuary supplemented by a pair of single Entasys to cover the far left and right. He added two Community VLF212 Subwoofers to supplement the system’s low-frequency performance for the church’s weekly contemporary mass. And, he chose Community’s dSPEC Networked Loudspeaker Processor to provide system equalization.

Since Flaherty had not used Entasys in a semi-circular sanctuary like St. Joseph’s, he asked Community’s Technical Applications Group to review his design. Community’s analysis showed that the design would achieve its goals of even coverage and uniform sound levels throughout the church.
Completed in late spring of 2013, St. Joseph’s new sound system includes Crown amplifiers and a Shure automatic mixer so that operation can be “hands off” for most services. For the weekly contemporary mass, Flaherty provided a special dSPEC input with a compressor section to manage the level. Musical groups can connect their own mixers to this input.

At the church’s request, Community custom-painted the Entasys columns to a color chosen to complement the carpet and trim. Flaherty says the church is very pleased with the results. “They’ve gotten nothing but complements about the appearance and the sound,” he said. “Those people who were sitting in the dead spots from the old system can finally hear everything.” Flaherty was also impressed with the musicality of the system. “The spoken word clarity is excellent,” he said, “and the subs add a pleasing low-frequency warmth to the contemporary service.”

Community R-Series Does Double Duty for CRC Soccer

Community R-Series Facing Back-to-Back Soccer Fields at CRCConsumnes River College (CRC) is a community college in South Sacramento, California. As a member of the Big 8 Conference in Northern California, CRC belongs to the California Community College Athletic Association (CCCAA) and has an active physical education and athletics program including both men’s and women’s soccer. In 2012, CRC expanded their program with a new baseball and softball field. And, this spring, CRC completed two new soccer fields with back-to-back bleachers and a common press box that serves both fields.

As part of this expansion, CRC published an RFP (request for proposal) for sound systems for its new soccer fields. After considering several alternatives, they selected a design from Associated Sound of Sacramento using Community R-Series Loudspeakers.

Associated’s design uses two Community R.25-94TZ loudspeakers, located on each corner of the press box roof and aimed at the local bleachers. A single R.5COAX99T, located between the two R.25s, covers the visiting team’s seating on the opposite side of the field. The loudspeaker system is duplicated on the other side of the press box for the second soccer field.

To save money for their customer, Associated designed the system with a single electronics package using a multi-channel QSC amplifier, a Symmetrix Jupiter 8 DSP that doubles as a mixer and a pair of Audio-Technica wireless microphone receivers. Game announcers control the system from simple wall plates on each side of the press box and have no reason to open the locked equipment rack except to access a storage drawer.

Associated engineer Dave Veden said, “the system can be heard clearly in the bleachers and across both fields.” Veden added, “as we were finishing the job, the Dean of Physical Education asked if she could plug in her iPAD to listen to the new system. She was very happy with the musical sound quality.”

Tommex Provides Quality Sound for Złotnicza Sports Park with Community

Zlotnicza Stadium with Community R2 and R.5 loudspeakers

Tommex Zebrowscy Sp. J. has recently completed the design and installation of a Community loudspeaker-based audio system for the Złotnicza Sports Park.

Złotnicza Sports Park is the most modern stadium in the city of Jelenia Góra in Lower Silesia, southwestern Poland. In addition to the floodlit football pitch, the stadium has an athletics track and is Class 4A PZLA certified for European championships. The stadium has a total seating capacity of over 3,600, with a main grandstand accommodating 1,558 people.

Jarosław Kraszewski of Tommex, the designer and project manager for the system, explained, “The sound system was required to cover the grandstand, ground seating and competition zones and for such large areas we naturally choose Community R-Series. Their all-weather durability, outstanding intelligibility and high efficiency combined with the wide range of coverage angles available means we can effectively implement them on any project of this type.”

Fourteen Community R.5HPTs on three line feeds are used for the main grandstand, while just two Community R2-52s on a fourth line cover the pitch and ground stands. The Community loudspeakers are powered by a Dynacord DSA 8410 4-channel amplifier. A Community dSPEC226AN handles signal processing and FIR filtering, with FIR filters matched to each loudspeaker so that frequency response characteristics are aligned and the sound quality optimised.

The commentary box, located in the center of the grandstand, houses a Dynacord CMS 600-3 mixer with a Sennheiser E825-S microphone, Sennheiser PRO HD380 headphones and two Denon DN-C110P CD/MP3 players. Tommex also installed a distributed ceiling loudspeaker system for the indoor areas of the grandstand.

“The Community loudspeakers will provide Złotnicza Sports Park with long term reliability. With excellent coverage and intelligibility in all areas, the system meets the needs of the stadium’s management and visitors alike,” concludes Kraszewski.
