Ken Dickensheets, CTO/Principal Consultant for Dickensheets Design Associates, has been involved in many notable projects with some of the most challenging being churches, where very often the importance of clear, highly intelligible audio is initially overlooked in architectural design.
Dickensheets is often called in to fix the sound systems in these sanctuaries, oftentimes relying upon solutions from Bose Professional Systems.
One of his more recent projects was the Transfiguration Greek Orthodox Church in Austin. There, Dickensheets encountered a small 250-seat sanctuary, but one with an extremely high ceiling for the size of the room – over 30 feet tall.
This, plus the marble and plaster finishes, resulted in a reverberation time of more than five seconds, quite long for a room of that size.
To resolve the situation, Dickensheets brought in several steerable-array loudspeaker systems ultimately finding the solution with a single Bose RoomMatch RM7040 array module, powered by one Bose PowerMatch PM8500N amplifier.
“The difference in the intelligibility of the sound between the Bose RoomMatch loudspeaker and every other speaker was like night and day,” he says. “That one speaker was able to give them the kind of sound they’d been in search of for ten years.”
Mark Stevens, President of San Antonio Sound & Light, the AV integrator on the project, says that the RoomMatch loudspeaker has the high-frequency articulation needed to address speech intelligibility in that kind of acoustically complex environment.
“The RoomMatch module has six high-frequency drivers mounted on a waveguide that is just perfectly suited for problems like these,” he explains.
Stevens adds that the RoomMatch loudspeaker was flexible enough in its ability to be mounted that he was able to position it almost 30 feet above the church’s altar and aim it down at a precise 45-degree angle.
“We needed the height and the angle just right to optimize the box for the space, and the RoomMatch module was able to be installed exactly as we needed it to,” he says.
