Denver Broncos stadium upgrades with Harman’s JBL Pro loudspeakers

With high expectations for its resident NFL franchise, the Denver Broncos, management at the Sports Authority Field stadium in the US installed a new AV system comprising JBL's Precision Directivity loudspeakers.

Denver’s legendary Sports Authority Field at Mile High, Colorado, US, recently opened for its 2013 season with a completely new AV solution inclusive of a loudspeaker system based on JBL’s new Precision Directivity 5000 series.

Minneapolis, Minnesota-based Parsons Electric installed the new audio system, which was designed by Dallas, Texas-based Wrightson, Johnson, Haddon and Williams (WJHW). The upgraded system included a retrofit of the stadium’s scoreboard loudspeakers, as well as wholesale changes to the bowl loudspeakers.

“We pulled every speaker out of the bowl and scoreboard and replaced them with substantially larger speakers with more modern horns and better dispersion,” said David Potts, field engineer, Parsons Electric. “The previous system wasn’t bad, but it was really thin and it was dated, so they didn’t have an abundance of coverage and output.”

Parsons Electric installed a total of 18 JBL loudspeakers flanking the scoreboard: 10 JBL PD5342 full range three- way loudspeakers, six PD5212 mid-high frequency loudspeakers and two AM5212 loudspeakers. The new bowl system, meanwhile, was equipped with 61 PD5342/64 loudspeakers, each paired with a JBL custom-made AL6212-WRX low-frequency loudspeaker. Moreover, every PD Series loudspeaker enclosure was treated with JBL’s WRX extreme weather protection.

“We did some steering to couple the low frequencies of the AL6212-WRX with the PD5342 loudspeakers,” Potts added.

Elsewhere, on the suite level, Parsons deployed 52 JBL custom-made CSMHS-DH12 weatherized loudspeakers, which each contain a 100v transformer. The suite level also features 26 AL6212-WRX weatherized devices.
Crowing the system, located under the deck and upper bowl, 36 JBL CSAW-266 and CSAW-211 loudspeakers were employed between “tusks” or large, forked beams.

With the Broncos off to a strong start and the new audio system in place, Broncos fans have good reason for excitement. “We now have a lot more SPL and the sound throughout the whole stadium has much more presence,” said Potts.
