INDIANAPOLIS, INDIANA - NOVEMBER 2011: Since its formation in 1985 on the burgeoning north side of Indianapolis, Indiana, College Park Church has grown consistently and rapidly. Its early meetings at a local hotel quickly overflowed and inspired a move to a local warehouse where, after a few years of fundraising, College Park set down roots in a new building all its own. But its blessing of growth continued apace, inspiring one, then two, then three Sunday services. Now, decades later, College Park Church is celebrating the completion of a new 4,000-seat sanctuary with raked seating that can accommodate the entire congregation (for now at least!). David Wright, president at Wright Consulting Associates, recommended a subwoofer solution with Danley Sound Labs TH-MINI subwoofers, which are small, (true to their name), tremendously efficient, and truthful (true to their brand). WCA arranged an audition for the church A/V tech team and recommended that subwoofers already designed be replaced with Danley models instead.
College Park Church's musical style is best described as contemporary, diverse... and big. A live band, a full choir, and an orchestra complement the sermon. Indeed, the services often incorporate dramatic reenactments and prerecorded multimedia support, both of which require full sound reinforcement.
"Originally some soft ideas about ground stacking subwoofers in fairly arbitrary positions along front walls and corners of the room led to inconsistent low end," said Wright. "Flying subs is always preferred by Wright but structural considerations conspired to nix the idea. The next best idea was to hide subwoofers underneath the center dais.
"But the space underneath the dais kept getting smaller during construction," Wright continued. "It was an ideal application of the Danley TH-MINI subwoofer, which we had flown successfully in other projects. The TH-MINI is the only subwoofer on the market that could be hidden under the dais and yet still deliver compelling deep bass to 4,000 seats." Although audio products used in audio systems are important, Wright is quick to point out that they are nothing without proper balancing and commissioning. "That intangible part of the system was done exceptionally well by Acoustic Dimensions, who we originally recommended to Aspen Group, our architect. By cleverly employing delays, listeners anywhere in the sanctuary naturally localize all sounds to the stage, the best part of the design and key to the performance of the system."
Looking to the future, Wright will again employ eight Danley TH-MINI subwoofers in Indianapolis' Shortridge High School, an historical location. In a state where basketball is king, (eighteen of the largest high school gyms in the USA are located in Indiana - and it was the inspiration for the movie Hoosiers) the school's new 4,000-seat gymnasium will be large enough to host large sectional tournaments. Wright and his employees Daniel Farrar and Russ Hoppel carefully modeled the space in EASE and determined that the bass component would be best served by flying two end-firing subwoofer arrays, each lobe aimed at one of two gigantic bleacher sections, to minimize spill from room surfaces.
But the modeling served an acoustics purpose first. "We worked to simultaneously keep the acoustic budget in line even while bringing a six-second reverb down to one-and-a-half seconds," explained Wright. "We considered a number of full-range solutions and planned to present them to the client as a 'good, better, best' option set." But we were surprised that the "best" option was two Danley Genesis GH-60 horns, one for each bleacher section. Its efficiency and tight pattern control would work in synergy with well placed acoustical treatments to maintain impact and clarity. "The numbers led us to the realization that the Danley solution would be less expensive than the original design. Wright said. "The Genesis Horn coverage and efficiency allowed us to replace nine other boxes with just two Danleys. The reduction in the total loudspeaker cost combined with the reduction in installation labor made the Danley solution the least expensive and also best performing."
