The church had initially invested in quality equipment such as Crown amps and a Soundcraft K2 console, and Hedden kept as much of the original equipment as possible.
The main room seats around 800-900 people. Hedden and his team installed a mono distributed system featuring a main centre cluster of two SPL-triktraps from Sound Physics Labs and two SPL-td1 subwoofers. SPL-triktraps provide wide-angle coverage of 60° x 60° and boasts a frequency response of 50Hz - 18kHz, +/-3dB. The compact, lightweight Baltic birch enclosure weighs only 106lb and arrays neatly. The SPL-td1 subwoofer is also a compact, high-output cabinet that provides low-frequency directivity with a small speaker array. The subwoofer cabinet houses two 12" low-frequency drivers in a proprietary vented box alignment. The enclosure is also made of Baltic birch on a 30° trapezoid angle.
Two additional Sound Physics Labs (SPL)-C3 Contractor Cubes on the left and the right provide lateral fill, while two SPL B-DEAP32 subwoofers do their job hidden in the organ chambers. The SPL-C3 Contractor Cubes deliver exceptional clarity and output from its 19" x 19" x 21.5", 105lb (47.6kg) cabinet. The SPL-C3's "petite" frame houses two 10" low-frequency drivers, four 5" mid-frequency drivers, and a single 1" HF driver with a 60° x 60° coverage pattern. The SPL B-DEAP 32 subwoofers utilize the company's patent-pending Boundary Dependent technology. Signal processing is from a Crown USM810, and the room and loudspeaker system were measured with a TEF 20 analyzer. The new system has a coverage deviation of +/-2 dB and articulation loss no greater than 5% Alcons, says Hedden.
Hedden concluded: "Overall it worked out very well. I couldn't have asked for a better system. The Sound Physics Labs loudspeakers are so well designed that they make it very easy to attain quality audio. Most importantly the church is very happy with the new sound system."
