Rothbury, MI (August 16, 2013)—The Electric Forest music festival in Rothbury, MI featured an Adamson E15 system on the Tripolee stage, provided by Detroit-based Burst Sound & Lighting Systems.
Burst operations manager Scott Ciungan said they used a complete E15 line array system, consisting of 24 E15 boxes—12 per side—with 24 T21 subwoofers stacked two high and 12 wide in front of the stage.
"The arrays were hung behind scrim on scat bays constructed to the left and right of the stage," Ciungan explaioned. "The subs were stacked to create one big, wide sub. In order to make the coverage more even across the listening plane, we delayed the last four subs on each side 7 milliseconds. We were able to get the low end down to 25 Hz which was really impressive."
Eight Adamson SpekTrix loudspeakers were placed on the lip of the stage for front fill. Eight more performed monitor duty, ground stacked to the left and right of the DJ booth.
"The stage was 70 percent DJ music with everything else electronic," Ciungan said "The system covered 300 feet and then just dropped off, which was exactly what we wanted. Nice and clean with no bleed into any of the other listening areas."
The Adamson system was powered by Lab.gruppen FP 7000 and 10000Q amplifiers. Burst utilized 14 Lake LM26 processors for the stage with XTA 424 processing on the TT21 subs.
