Danley Genesis Horns Deliver Sound Reinforcment At Green Bay’s Lambeau Field

Lambeau Field, the 73,000-seat “Frozen Tundra” home of the the reigning NFL champion Green Bay Packers, has been outfitted with a new distributed sound reinforcement system headed by Danley Sound Labs Genesis Horn, Synergy Horn, and Tapped Horn loudspeaker technologies.

The old sound system relied on a single cluster of loudspeakers positioned at the scoreboard on the north end of the bowl. Apart from the sometimes surmountable but ever-daunting challenge of throwing sound long distances while still providing even coverage, the architecture of Lambeau Field guaranteed that any system that relied on a single point source, no matter how pricey or sophisticated, would be inadequate.

Specifically, a hemispherical ring of windowed skyboxes and suites tops the bowl, providing a surface that generates high-SPL, broad-bandwidth reflections that wreck intelligibility. The Packers hired Anthony James Partners (AJP) of Richmond, Virginia to design an improved sound system. With no ties to any vendor, manufacturer, or integrator, AJP provides its clients with ideal, unbiased solutions.

“The biggest challenge at Lambeau was the expected environmental conditions,” explains Larry Lucas, director of audio engineering at AJP. “The Packers were understandably unbending about the placement of equipment. To prevent injuries from falling snow and ice (recall the stadium’s nickname!), no structures of any kind could be placed above seats.

“So even though we were using a distributed approach, we were left with the task of covering large areas of seating using a long throw from loudspeaker positions that were much less than ideal. The Shaded Amplitude technology of Danley’s Genesis Horn promised to provide that coverage without blasting the fans that were close or whispering to the fans who were far.”

The distributed system is primarily comprised of 16 enclosures placed on top of the enclosed suites, around the perimeter of the field. Each of the enclosures contains a Danley GH-60 Genesis Horn and a Danley TH-118 subwoofer. The Genesis Horn and subwoofer combination covers the majority of the seating, with the Genesis Horn Shaded Amplitude roll-off positioned such that seats both near and far receive the same SPL.

Due to Lambeau’s blustery weather, outdoor enclosures measuring approximately 6 feet by 7 feet were custom designed by Pro Media Ultrasound, the system installer for the stadium. Nineteen Danley SH-100 loudspeakers are spaced around the stadium in between outdoor speaker enclosures providing near-fill for seats below the suites that fall outside the Genesis Horn’s beam.
