L-Acoustics K2 a home run for Dodger Stadium

Dodger Stadium recently wrapped up a multi-faceted renovation with a new L-Acoustics K2 line source array sound system installed covering the stadium seating, and L-Acoustics A15i and X8 speakers covering the new Centerfield Plaza and existing Outfield Pavilion areas.

With the addition of an L-Acoustics K2 system, Dodger Stadium, which was built in 1962, keeps its original look, while updating its feel with a modern, powerful sound system capable of handling any event.

The installation marks the first Major League Baseball project for L-Acoustics and one of the most important installations of the manufacturer’s systems in the global sports market.

“Our goal was to have a state-of-the-art sound system at the stadium,” said Derek O’Hara, director of planning and development for the Los Angeles Dodgers. “Dodger Stadium is designed the way ballparks were at the time it was built, with point-source sound systems that need to throw long distances.

“We wanted to modernise the stadium’s sound, allowing it to host many different types of events besides baseball, while keeping the park’s architecture as traditional as it has always been.”

The K2 makes the long throw – over 600 feet from arrays to top deck seating – with ease, as well as with total phase coherence, intelligibility and impact.

The new Dodger Stadium sound system comprises two PA towers supporting a total of 62 K2 loudspeakers: 20 enclosures are flown in both the left and right main arrays, flanked by adjacent side arrays of 11 more K2 per tower.

For low-end reinforcement, 21 SB28 subs are positioned on the right field tower, with three SB28 on the left field side. Twenty coaxial X8 serve as left and right Pavilion delay fills. To further enhance the fan experience, L-Acoustics A15i and X8 speakers are deployed in the new Centerfield Plaza and Outfield Pavilion areas.

The entire system is powered by 32 L-Acoustics LA12X amplified controllers. Two Milan certified P1 processors for AVB networking and processing reduce cabling, provide atmospheric control and monitoring for temperature and humidity variations, enhance system communication and control, and further future-proof the venue’s sound infrastructure.

O’Hara, who has a background in architecture and, at one time, was a scout for the team, worked with the L-Acoustics support team and the collective experience of system designer Idibri and integrator Pro Media Audio & Video to keep as much of the sound within the stadium – including the powerful low end coming from the ballpark’s new SB28 subwoofers.

“The subwoofers are arranged in an endfire configuration, which provides some critical directionality to the low end, keeping it from escaping the stadium walls and keeping the impact on the seating,” O’Hara explains. “The K2 is a great sound system, and its horizontal directivity makes it a strong ally for sound control issues. But so much of what it can do is also because of the expertise that L-Acoustics, Idibri, and Pro Media brought to the project.”

Ryan Knox, senior consultant for Idibri on the Dodger Stadium project, says that new stadium architectural configurations modified the spectator seating and standing areas in the outfield section, posing a coverage challenge. That was resolved using L-Acoustics Soundvision modeling software, which helped finalise the placement of the speaker-support towers. “That was a two-to-three month process itself, and Soundvision is a great tool for that,” he says. “It models quickly and accurately, and it has an excellent workflow.”

Putting systems of this scale into the Los Angeles area comes with its own unique requirements. “In addition to keeping the sound system installation’s look consistent with the architecture of this iconic stadium, we also had to meet Southern California’s seismic requirements,” says Demetrius Palavos, project executive for the integrator, Pro Media Audio & Video.

To secure the structural-engineering certification of the sound installation, Pro Media and L-Acoustics engineers worked together, ultimately deciding to upgrade the standard K2 external rigging hardware with a new exoskeleton devised by Pro Media and L-Acoustics engineers.

“We then built a mockup of that in the L-Acoustics Los Angeles warehouse to verify and validate the modifications that we made before we went to fabrication,” says Palavos. “It had to take in a number of critical points, such as soil composition and rigging heights and weights. But we met all the certification requirements and kept the K2 looking sleek and cool. It’s a very flexible box.”

O’Hara says that choosing a new sound system was a learning experience, which required him to speak with leading system designers and manufacturers. A key inflective moment, though, was when he asked each manufacturer to rate competing systems. “There was a lot of respect for L-Acoustics from all industry players,” he recalls. “That meant a lot in the decision. We feel we now have the best sound system in major-league baseball, and we’re excited about it.”
