San Antonio, TX (April 11, 2016)—Even though it was only built in 2002, the AT&T Center in San Antonio recently underwent a massive renovation in 2015. That included a new HD main scoreboard and a L-Acoustics sports entertainment sound system package designed by Wrightson, Johnson, Haddon & Williams (WJHW) and installed by LD Systems.
“The previous sound system featured an exploded cluster design, and integrated amplifiers in the loudspeaker cabinets made maintenance a challenge; in order to service them, the entire self-powered cluster needed to be lowered to the floor,” recalls LD Systems sales engineer Kevin Broussard. “Also, it did not adequately cover every seat in the house, and the sonic difference from one section to the next was quite noticeable, so the venue really needed a system that could provide power and punch evenly to every seat in the house.”
WJHW based AT&T Center’s sound system topology on the L-Acoustics K2 system design for Houston’s Toyota Center, home to the NBA Houston Rockets, a few years prior—this time specifying L-Acoustics’ Kudo WST line source system.
LD Systems flew and calibrated the new sound system, which is primarily comprised of 72 Kudo flown in six arrays of 12 enclosures plus 24 SB28 subs flown in six cardioid arrays of four enclosures and located directly behind the main arrays. Each main/sub array pair was flown using a custom-fabricated rigging beam that reduces the four hang points for the main and sub arrays down to only two points, allowing the Kudos and SB28s to be “locked” together as single arrays and fully retract into the roof structure to accommodate touring events if necessary.
In addition to the Kudo and SB28 arrays, 15 L-Acoustics ARCS WiFo speaker arrays are positioned around the upper perimeter of the arena for fills behind obstructions to the main arrays, while a dozen 12XTi coaxials are mounted to the underside of the scoreboard to address the courtside and floor areas. A combination of 34 LA8 and four LA4X amplified controllers power and process the arena’s loudspeaker system.
