A recently completed renovation project at the 600-seat Studebaker Theater, located in Chicago’s Fine Arts Building in the city’s Loop neighborhood, includes a new sound reinforcement system headed by L-Acoustics Kara II loudspeakers in a joint design by consultant Threshold Acoustics and integrator OSA Integrated Solutions.
“Threshold Acoustics was contacted by the venue’s new owners who required a new AV system, including the PA system,” says Brandon Gardner, director of AV Integration for OSA, which installed the new loudspeaker deployment this past spring along with a DiGiCo Quantum225 front of house console and D2-Rack as part of the project. “Given the scope of the work on the theater and the time frame, it was decided that OSA and Threshold would work together on a design/build approach that would get the theater the sound it needed as efficiently and effectively as possible.”
The effort extended to a new infrastructure for rigging, power, and cabling, designed by Schuler Shook, part of which supports the new PA system, which would be asked to provide the sound for the wide array of events and performances the theater is known for. In the early 1900s, it was vaudeville and operas; today, the schedule also includes musicals, orchestral concerts, dance performances, and corporate events, as well as NPR’s long-running news quiz show, Wait, Wait… Don’t Tell Me!
Older venues like the Studebaker Theater can present unique challenges. In this case, coverage was key—getting even sound into the far reaches of the room and across the seating in the balconies, which had never been properly covered by previous sound systems, says Gardner. “That, and having a PA that would work for high-decibel concerts as well as nuanced productions like corporate events and Wait, Wait…,” he explains. “Kara II can do all of that and still have a low profile, letting the beauty of this theater shine through.”
Mercer M. Aplin, senior consultant for Chicago-based Threshold Acoustics, says the geometrically diffuse space was indeed a challenge, as was the sophisticated production scheduled for this past summer, which opened the new and improved Studebaker Theater: Skates, a new musical described as “Grease meets Hairspray with a dash of Xanadu,” and starring American Idol alums Diana DeGarmo and Ace Young.
“The audio renovation was complex and time was tight, and we were at the mercy of the same supply-chain issues that the rest of the professional AV industry was experiencing,” says Aplin. “So we decided to partner with a contractor that could assist with the engineering efforts and with coordaining the installation of miles of new conduit. We partnered with OSA because they have experience with complex renovations and, as a rental house, they could temporarily fill in any gaps in the system with rental equipment while we were waiting for the new gear to arrive.”
Threshold went with an left-center-right design, one that would address the venue’s theatrical requirements, with the center cluster tuned for vocals, and the left and right as main music arrays. The balconies — there are two, with the lower one larger — were the main task, and using L-Acoustics Soundvision software, Threshold was able to position a combination of 5XT and X8 loudspeakers to cover those spaces.
“We used two lines under the lower balcony — one line of 5XT and one of X8 — in order to get low-frequency coverage to the main house mix position under there. We utilized a similar technique with a single line of X8 to serve the balcony seats and a second mix position on the balcony,” Aplin explains. “The Studebaker Theater presented us with some real challenges and L-Acoustics offered us real solutions.”
The new system comprises eight Kara II loudspeakers per side, with a center hang consisting of eight Kiva II loudspeakers, while four flown KS21 subwoofers provide the low end. Five 5XT loudspeakers line the lip of the stage as frontfills, with five more used to reach under-balcony areas. A combination of 20 X8 speakers are used as sidefills, deeper underbalcony fills, upper sidefills, and coverage for the VIP seats. Four LA2Xi and eight LA4X amplified controllers power all loudspeakers.
And every one of those components serves a specific purpose in addressing the venue’s acoustics. “These old theaters were created before amplification and were designed to make the human voice heard throughout, especially in the corners,” explains Kevin Scott, technical director at the Studebaker Theater. “Pushing amplified sound into the space creates a mess of reverb and reflections. L-Acoustics speakers were carefully chosen to be able to have pinpoint-precise audio into the corners, especially under the balcony. The result has been tremendous; we can turn the system on half as loud as before and get twice the clarity and coverage.”
Scott notes that Threshold Acoustics carefully charted the room’s challenges, using pink noise to map its reflective signature. “Our new high-quality Kara II PA, combined with some acoustical treatments, like curtains, has really made the Studebaker Theater’s sound pop,” he says. “Plus, it’s a very versatile, dynamic, and multipurpose system that works well for loud music, spoken word, and everything in between.”
