Green Bay Packers Score Danley System

Lambeau Field, home to the reigning NFL champion Green Bay Packers, recently got a new distributed system, based on Danley Sound Labs’ Genesis Horn, Synergy Horn, and Tapped Horn loudspeaker technologies.

16 Danley Genesis Horns coupled with 16 Danley TH-118 subwoofers in custom-built enclosures cover iconic Lambeau Field in Green Bay, Wisconsin.
Green Bay, WI (November 18, 2011)—Lambeau Field, home to the reigning NFL champion Green Bay Packers, recently got a new distributed system, based on 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. The architecture of Lambeau Field guaranteed that any system that relied on a single point source would be inadequate due to a hemispherical ring of windowed skyboxes and suites atop the bowl, providing a surface that generates high-SPL, broad-bandwidth reflections that wreck intelligibility. The Packers hired Anthony James Partners (AJP) of Richmond, VA to design an improved sound system.

“The biggest challenge at Lambeau was the expected environmental conditions,” said 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, 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’ x 7’ were custom designed by Pro Media Ultrasound, the system installer for the stadium. A total of 19 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.

A pair of additional Genesis Horns cover the south end zone, which will be converted to seats and party decks next season. Fifty-six Danley SH-Mini’s provide coverage for club seating and the Legends Lounge. A new Yamaha M7 digital console gives stadium engineers the ability to recall mixes, and a BSS London-series DSP system provides all system equalization, dynamics, routing, and loudspeaker management. Despite the fact that a Genesis Horn contains 18 drivers, the number of amplifiers required to cover the 80,000-plus seats at Lambeau is five Crown IP-5000s, nine IP-9000s, and eight IP-12000s. Danley Sound Labs’ Mike Hedden commented, “Our products produce industry leading high sensitivities and cutting edge technologies. Other loudspeaker manufacturers would have had an amplifier count at least double ours along with much more required electrical service demands. When you compare this, and then add our lower electrical cost of actual operation, you’ll see why Danley Sound Labs is one of the most “green” loudspeaker companies on the market today.”

The Packers’ fans, administration, and even players have praised the new sound system. “The improvement is not at all subtle,” said Lucas. “Fans have gone out of their way to let the administration know that Lambeau’s sound reinforcement system is a significant improvement. That very positive feedback has made them feel comfortable with the investment they made.”
