Chester, PA - Community Professional Loudspeakers is launching its new Distributed Design Series of ceiling loudspeakers. The line will be officiallly unveiled at the Audio Engineering Society Convention in San Francisco, November 5-7. Designed for exceptionally high quality sound with very wide, uniform coverage, the series debuts Community's innovative Drop-Stop™ and Twist-Assist™ features, making the installation process easier, faster and safer.
Drop-Stop™ and Twist-Assist™ are truly unique features to aid installation, providing that elusive 'third hand' installers frequently wish for. The Drop-Stop™ feature provides spring-loaded legs to support the back-can on the included rails and C-ring, so the installer no longer needs to hold the can against the tile while tightening the clamps. Twist-Assist™ performs a similar function for the baffle assembly: when the loudspeaker back-cans are pre-installed into a conduit system for later termination, a simple twist of the baffle into the back-can brings the Twist-Assist™ clips together, supporting the baffle assembly while the installer fastens the screws.
The series comprises seven products, including five full-range, standard-depth back-can models. The D4 is a 60W, 4.5-inch model; the D5 and D6 are 5- and 6.5-inch 100W models; the D8 is an 8-inch, 150W design, and the D10 is a 10-inch, 200W model.
Also available is the D4LP, a low-profile, shallow back-can model that is only 3.6 inches (92mm) deep, for installations where available depth is limited. Completing the range is the D10SUB, a 200W 10-inch subwoofer that provides powerful LF reinforcement for entertainment applications.
Each of the full-range models is a true coaxial loudspeaker, with a compression driver concentrically located so that high frequencies emerge through the center of the low-frequency driver's magnetic structure and cone via a precisely contoured Tru-Phase™ HF waveguide. This special construction provides consistent, wide dispersion up to 16 kHz, all but eliminating high-frequency beaming. Further pattern improvement is achieved by precisely mounting the low frequency driver (and its concentric HF driver) dead-center in the baffle, as contrasted to the offset designs used by others.
"Most ceiling loudspeakers typically have a half-inch or greater 'step' in their baffle where the grille is attached, with the low frequency driver rear-mounted behind the grille plate," explains Community Founder and President Bruce Howze. "These designs produce a host of unwanted reflections and diffraction effects. We've designed the Distributed Design Series with baffles less than 1/8-inch from the grille, creating an uninterrupted planar surface between the baffle and ceiling surface for diffraction-free HF driver acoustic loading and a smooth, predictable pattern. The result is optimal coverage without dead zones or overlaps."
The Distributed Design Series incorporates Community's patented Carbon Ring Cone Technology, which increases the effective surface area of the cone. Powerful magnetic structures and efficient coils ensure high output, resulting in greater headroom per power amplifier. And all models in the series comply with ETL standards, including UL1480, UL2043 and CSA60065.
Each model is available as a complete unit with everything needed for standard installations. The drive unit and face plate assembly and the back-can may also be purchased separately. The competitively priced Distributed Design Series can be used in 8 Ohm or 70V/100V line applications, and will be available for sale in December 2010.
