Rockford, IL (July 24, 2017)—The Sinnissippi Music Shell at Sinnissippi Park in Rockford, Illinois is a beautiful piece of architecture—but it can’t bear the weight of a typical left-right PA system. Faced with answering that challenge, Clearwing Systems Integration brought in an L-Acoustics Kiva II system for this summer’s annual Music in the Park Series.
“You’d typically like to have a left-right stereo system, with a hang on either side of the stage, but it doesn’t always work out that way,” says Clearwing Systems Integration systems design engineer Mik Moore. “At Sinnissippi Park, given the architecture and the load-bearing limits we faced with this kind of stage design, we had to work with just one line array. Because the seating areas are wide and extend up a hill behind the fixed seats, it was more of a challenge than it looked.”
Clearwing fielded an L-Acoustics Kiva II line array in order to make use of 100-degree horizontal coverage. The compact array weighs 31 pounds per module, which gave the audio provider enough leeway to also put three 15-inch subwoofers atop the hang. Polar Focus rigging elements that fit a motorized lift are used atop the array and an anti-sway stabilizer sits bar underneath to keep it steady in the breeze.
“The horizontal dispersion pattern of the Kiva II is just fantastic,” says Moore. “One of the first big shows of the series had over 3,000 people in the seats and more on the grass around them, and the producers told us that everyone heard everything, even off the side and on top of the hill.”
