It might have seemed difficult to meet all of these goals, but a RoomMatch loudspeaker system from Bose Professional Systems was just the right solution.
Covenant Communications, an AV systems designer and integrator in Houston, used two RM12020 modules, one RM12010 module and an RMS215 subwoofer in each of two L/R arrays, all powered by three Bose PowerMatch PM8500N eight-channel amplifiers. That was all it took to fulfil all of the needs of this complex acoustical space.
"The six compression drivers in each cabinet from two arrays provided all the directivity we needed to tailor the sound coverage to all of the seats in the worship hall, and we were able to do that without further exciting this challenging acoustical environment with more cabinets yielding higher SPL's," observes Joe Smart, the sales manager for Covenant Communications and the system's designer.
Noting the concrete flooring, the copious amounts of highly reflective solid drywall, and the fact that there was no acoustical treatment in the ceiling space, he says, "A predictable coverage pattern for the sound was absolutely critical. And that's why the RoomMatch speakers were the perfect solution: We were able to cover the space consistently and coherently with a minimum number of boxes."
In addition to the RoomMatch modules used in the sanctuary, Covenant Communications also installed 70V Bose DS40 ceiling speakers outside of the worship centre, to cover overflow areas, networked to, and powered by, the PowerMatch amplifiers. "I've gotten more compliments from the end user on this system than other projects I can remember. The system is really musical, and we did it all with a minimum of hardware," says Smart. "It was definitely a case of less really being more."
