MLS (Major League Soccer) team the Houston Dynamo has recently moved to the newly completed BBVA Compass Stadium, which features a Harman sound system comprised of over 200 JBL loudspeakers, 50 Crown amplifiers and a BSS Audio distribution and control system.
Wrightson, Johnson, Haddon and Williams of Dallas, TX, handled the design of the audio system, led by senior associate Gary White. Ford AV of Oklahoma City, Oklahoma was the audio/video contractor for the project.
The main bowl of the stadium, which seats 30,000, boasts a combination of 90 JBL AE Series and PD Series speakers. Models include JBL’s AM7215/95-WRX and AM7215/26-WRX full-range two-way 15” speakers, and PD5212/95-WRX and PD5212/64-WRX two-way 12” high-output speakers. All of the speakers have JBL’s WRX extreme weather protection treatment and are used in the main seating bowl of the stadium.
Furthermore, 113 JBL Control Contractor speakers are installed throughout the facility, including the Control 26CT and 24CT in-ceiling speakers and Control 25T and 28T-60 indoor/outdoor speakers, along with two JRX112M monitors. The speakers are powered by 45 Crown CTs Series CTs-3000-LITE and seven CTs-2000-LITE amplifiers.
The system is networked together by an extensive complement of components from BSS Audio Soundweb London, including six BLU-800 devices with CobraNet, three BLU-160 devices, three BLU-120 I/O expansion devices, a BLU-80 device with CobraNet, seven 9015US Wall Panels, 12 BLUCARD-IN input cards and 29 BLUCARD-OUT output cards.
“BBVA Compass Stadium required a multi-purpose sound system that could handle public address and music throughout the facility,” commented White. “We’ve had great success with Harman products in the past and AEG (Anschutz Entertainment Group), one of the major promoters of Major League Soccer, has a partnership with HARMAN so it was a good fit all around.”
The audio system within the stadium includes a number of zones, including the main bowl area, the entrances, 34 private suites, the restrooms and other locations. Additionally, separate dedicated sound systems are installed in the stadium’s Premium Club, the press room and the post-game interview room. “The BSS Soundweb London components were absolutely essential in getting all of the different audio signals properly routed to all these diverse areas,” White explained. “They make what could have been an overly complex system extremely manageable.
"The JBL AM7215 and PD5212 models are ideal for the main stadium area,” he continued. “They deliver high SPL and their rotatable waveguides enable optimum positioning and the ability to orient the speakers either horizontally or vertically. They are also weatherproofed and durable, which is almost as important a consideration as their sound quality and coverage pattern in a city like Houston with its extremes of weather and temperature.”
Jason Werle, project manager for Ford AV’s Dallas Division, explained the key challenges involved with the installation: “In order to meet a deadline of when the lifts were no longer [allowed] on the field, our first task was to install all of the bowl speakers. At the time, the field was highly populated and made it challenging to navigate around the bowl. We installed all these speakers from the field level using an articulating boom and chain hoists. Any project of this size will have difficult cable pulls and Dynamo was no exception.”
“We went with the JBL Control in-ceiling and outdoor speakers in the other areas of BBVA Compass Stadium because they are compact and can be installed inconspicuously, yet deliver powerful sound,” added White.
