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.”
