Tsai Performance Center Upgrades with EAW AnyaCanton, Massachusetts-based Communications Design Associates (CDA) recently designed a new sound reinforcement system for the Tsai Performance Center at Boston University. The upgraded system features Eastern Acoustic Works (EAW) Anya adaptive column arrays that blanket the room with even, high-quality audio. "When the original system was installed in the early 90s, the room was primarily used for lectures, not performance," says Joe Patten, associate designer for CDA. "As the space has evolved, it was clear they needed a system that could accommodate a variety of performances in addition to regular lectures." During the evaluation process, Patten set up a number of demos including EAW KF720 line arrays. During the presentation EAW extended an invitation to the group to tour EAW's factory and hear a demo of the adaptive performance system installed at Hanover Theater in Worcester. "After that demo the associate director of production services at Boston University looked at me and said 'we're done -- this is what we need -- we don't need to hear anything else' and that was that," Patten explains. The resulting system design consists of left-right Anya line array columns, three modules each, and a single QX loudspeaker located in the center. Boston Light & Sound, located in nearby Brighton, provided installation and integration services for the project. Patten adds, "I can't say enough about the quality, expertise, and timeliness of that crew. Zeke Zola led the effort and it was absolutely perfect. They are a really impressive group." Each three-way, full-range Anya array module features 14 1" exit/35mm voice coil HF compression drivers loaded on a proprietary HF horn. Six 5" MF cone transducers, arranged in two columns of three, use Radial Phase Plugs and Concentric Summation Array technology to enter the horn and sum coherently with the HF wavefront. Dual 15" LF cone transducers use Offset Aperture loading to increase the spacing of the apparent acoustical centers, extending effective horizontal pattern control well into the LF range. Every Anya module also includes a field-replaceable power and processing unit with 22 channels of digital signal processing and amplification to drive each of the module's 22 transducers. "I have to admit, I have never been that impressed with a loudspeaker in my life," Patten concludes. "It is a game-changer listening to those loudspeakers. We were at the Hanover Theater and I'm listening and looking for the subs -- and there were none. The steering and coverage is incredible."
