Raleigh, N.C-Area Space is Spec’d for a New Sound Experience

Indiana's Custom Sound Designs uses technology to help overcome physical space limitations in an adaptive-reuse industrial site-turned-church.

Raleigh First Assembly worships in an adaptive reuse industrial site outfitted with L-Acoustics' Kiva line arrays. A Yamaha CL5 digital mixing console fed by RIO digital stage boxes drives the L-Acoustics' system.

Like many audio system design projects, the biggest challenge in specifying sound for a house of worship is often overcoming the limitations of the physical space. That was the situation that Ft. Wayne, Ind.-based Custom Sound Designs (CSD) Group Inc. faced in a recent project for First Assembly Church of Raleigh, N.C., and a system based on L-Acoustics’ Kiva and ARCS WiFo product lines controlled by a Yamaha CL5 digital audio console was its reported solution.

For a millennium or more, worship spaces have traditionally been works of high art in architecture—soaring spaces featuring the finest materials and designs to inspire a sense of awe and wonder. Today, however, especially in the rapidly growing evangelical world, new churches are often likely to be former retail locations or spaces in commercial parks rather than sites purpose-built from the ground up as houses of worship.

Adaptive reuse meets audio specification solutions

A perfect example of this, Raleigh First Assembly acquired a 58,000-square-foot space that had the advantage of being located right in the middle of its mission zone, but the abandoned industrial property presented challenges as massive as the space.

“This is not just a case of it being a large and acoustically unfriendly space,” explains CSD President Doug Hood. “In some ways it was closer to a new-construction project than a typical renovation, but the nature of the construction limited what could be done. The site was originally a manufacturing facility, so it was a large and almost completely open environment. Things like support beams are central to the structure and, therefore, had to be worked around in terms of the design.”

" ... although the building itself is very large, the ceiling is not super tall, so we needed something that could fill this enormous room with power and clarity and still keep a relatively small footprint."

CSD turned to the L-Acoustics Kiva and ARCS WiFo ranges for the loudspeaker end of the equation, deploying a dozen Kiva modules in left and right arrays of six, then extending that coverage to the sides with an ARCS Wide and ARCS Focus (aka “WiFo”) paired together on each side for outer fill.

The room is much wider than it is deep—one of the overall design challenges by itself—and so the system deployment is wide enough that a center fill is needed. CSD took the novel and cost-effective approach of flying a single 115XT HiQ enclosure, typically billed as a stage monitor, in the center position for its high directivity and SPL, while a total of seven compact 5XT coaxial enclosures are spaced out across the stage lip in recesses as front fills.  continued >>
