The Fort Worth campus’ Amon G. Carter Stadium
USA - For fans of Texas Christian University’s (TCU) Horned Frogs football team, this school year’s Big 12 conference football season was bigger and bolder than ever thanks to the kick-off of a $118m expansion of the Fort Worth campus’ Amon G. Carter Stadium.
Among its many improvements, the first phase of this multi-year initiative notably involved a significant upgrade of the nearly 50,000-capacity stadium’s video and audio facilities, including a new L-Acoustics K1/Kara loudspeaker system designed and installed by local integrator Electro Acoustics (EA).
According to EA Account Manager Ryan Walker, who has been with the firm for 20 years, the project actually marked the second L-Acoustics system to be installed on TCU’s campus. In 2015, the company installed a Kara loudspeaker system paired with SB18i subs at the school’s Garvey-Rosenthal Soccer Stadium, home to the popular Lady Frogs women’s soccer team.
“After discussions with Ryan and Chris [Jordan, EA president], as well as our own experience with L-Acoustics at our soccer venue, we knew it would be the right choice for our football stadium,” says TCU senior associate athletic director T. Ross Bailey, who also overseas facilities & operations.
When the university revealed that it would be installing a much larger 5,500-square-foot video display at the top of the north end-zone seating section at ‘The Carter’, the Electro Acoustics team contacted L-Acoustics sports facilities application manager Gino Pellicano for product guidance and Soundvision design assistance.
“Working to maximum height requirements, the new video board - a massive 100+ feet wide and nearly 50ft tall - took most of the space, leaving less than 12 vertical feet to hang our loudspeaker arrays in the area above the display,” Walker recalls. “With such tight space constraints, we needed a fairly compact loudspeaker system that could still throw 500ft and push 95 to 98dB at that distance when needed. Gino suggested that we use the K1, which to my knowledge is the only solution on the market that could check off each of those required boxes for us.”
EA Systems designer Steve Burge worked with Pellicano on the design of the football stadium’s new system, which currently features three centrally positioned K1 arrays each comprised of six enclosures firing down the field to cover the far southern half of the bowl.
To address the fans on the closer northern half, a total of 16 smaller Kara enclosures were also flown directly above the video board. These were divided into arrays of seven, five, and four enclosures, tailored to the different heights of the nearby seating stands. Dual hangs of five SB28 subs are flown behind the centre K1 array for LF impact, and all of the arrays are visually concealed behind a scrim emblazoned with the home team’s moniker.
On the underside of the display, six short-throw X12 enclosures provide downfill coverage to the areas in the shadow of the video board. Furthermore, q2 LA12X and seven LA4X amplified controllers power the entire loudspeaker complement, which is also networked via a new Milan-compliant P1 AVB processor.
