Oklahoma City’s premier large event venue, the Chesapeake Energy Arena is also home to the NBA’s Oklahoma City Thunder. Modernising its sound system for the Thunder’s 2016-17 season, it now has the first large-scale use of Fulcrum’s CS121 subwoofers and the NBA’s first permanent installation of EAW’s Anya adaptive-array system.
Designed by Marsh/PMK’s Jerrold Stevens and installed by Ford A/V, the advanced technology audio solution gives the Oklahoma City Thunder a sound to match their name. ‘The sound system needed excellent intelligibility, fidelity, output and bandwidth to enhance the overall fan experience and become more competitive with other NBA arenas,‘ Stevens explains.
‘Cardioid was a huge factor in the arena design – vertical subwoofer arrays are ideal for providing smooth coverage to the seating bowl and keeping sound energy off the floor. However, the large centrally located scoreboard precluded any loudspeakers directly over centre court. Forced to hang subwoofer arrays around the scoreboard’s perimeter, I knew cardioid patterns were necessary to minimise interference between arrays.’
Stevens was familiar with Fulcrum’s passive cardioid line array modules and their ability to eliminate excessive rear low frequency radiation without requiring additional drivers, amplifiers or signal processing channels. ‘When Fulcrum co-owner Dave Gunness told me about their new line of passive cardioid subwoofers, the timing couldn’t have been better,’ he says.
Stevens’ design includes four vertical arrays of six Fulcrum CS121 21-inch subcardioid subwoofers above the scoreboard’s four corners to complement the Anya columns above its four sides. Stevens also deployed two pairs of delayed fill CS121 subwoofers for low-frequency coverage in the upper corners of the arena.
‘I’m so glad Fulcrum figured out passive cardioid subwoofers in time for this amazing project,’ Stevens reports. ‘They eliminated the need for an additional ring of active cardioid cancellation subs above the scoreboard, and helped deliver system cost and performance benefits that made for one very happy customer.’
