DANLEY SOUND LABS | JERICHO ericho is the second-generation of Synergy Horns from Danley Sound Labs. There were often multiple woofers and midrange devices in a single first generation horn, but the limitation was the single compression driver at the apex of the horn. In order to build higher power full-range Synergy Horns, Tom Danley had to find a way to combine the output of multiple compression drivers as well. Up until this time, no-one had been able to get compression drivers to couple over their entire range. The first Jericho, the J1, featured 15 drivers - six 18-inch woofers, six six-inch mid-range drivers and three 1.4-inch high-power compression drivers, coupled together through an ingenious isophasic combiner that made it possible for the J1 to produce levels in excess of 145dB SPL from 47Hz to 18KHz. The J1 debuted in Nevada in 2010. Immediately, calls began coming in from stadium audio providers asking about availability and within two months, the first Jericho stadium install was complete - LaVell Edwards Stadium in Provo Utah. Danley used just four J1’s to cover over 63,000 football fans in this outdoor stadium. Following the successful J1, was the J2, a 90º by 60º Synergy Horn with 42 drivers, 12 of them one-inch high-frequency compression drivers. The J2 does much of the heavy lifting

in Mercedes Benz Stadium in Atlanta, Georgia. Next came the J3, it features 18 drivers in one horn and produces levels in excess of 140dB SPL. The J3 is used in multiple stadiums - perhaps the most impressive use of the J3 is in Powell Hall, the home of the St. Louis Symphony Orchestra. The St. Louis Symphony chose the J3 strictly on the basis of its sonic performance. The J4 - offering 30º by 10º - is perfect for when you need to project high frequencies long distances. A total of 64 compression drivers sharing a single horn produce levels in excess of 148dB SPL from 600Hz to 12KHz. The J5 Caleb is a monster - its 40º by 15º horn stands 10ft tall and weighs a ton. Inside are 108 drivers coupled into a single horn. The J5 is capable of astonishing levels and pattern control unmatched by any other loudspeaker. Inside Kinnick Stadium in Iowa City, Iowa, the J5 projects sound from one end of the football field to the far seats over 700ft away. The newest member of the Jericho family is the J6, featuring 24 drivers in a new, more efficient combiner, this 40º by 20º Synergy Horn, capable of levels in excess of 148dB, is being used in multiple long throw applications. www.danleysoundlabs.com
