“Miami Nice” - L-Acoustics Is The Ultimate Choice For Ultra Music Festival 2015

24 April 2015

“Hot, hot, hot!” is what you get when you put the Ultra Music Festival on in Miami during Spring Break. But “cool” is the sound you get with a lineup that includes EDM legends like Krewella, Bassnectar, Porter Robinson, Die Antwoord, Big Gigantic, Chromeo and Gorgon City, all performing through an L-Acoustics K2 line array sound system.

Ultra Music Festival 2015, which took place Friday to Sunday, March 27 to 29, drew thousands of music fans to Bayfront Park in downtown Miami, which has hosted the event since 2012. But not since the festival debuted in 1999 has the sound been this good. 

“We’ve been doing the Ultra festival for a long time and have become very familiar with what a system needs to be able to do this kind of show right,” observed Andre Serafini, Founder and President of Beach Sound, the Miami Gardens-based sound reinforcement provider for Ultra over the past decade. “Bayfront Park can be a challenging venue for this kind of music, but the L-Acoustics systems handled it without a problem, and even overcame some of the venue’s most challenging restrictions.”

Those challenges included keeping the sound for each stage contained within its area and avoiding overspill into nearby stages. For the Live Stage, Beach Sound assembled a K2 sound system whose main array consisted of 24 K2 enclosures flown 12 per side.

“The K2 has very precise, incredibly accurate off-axis performance, which enabled us to keep the sound on the crowd and away from any of the other nearby stages,” Serafini explained, noting that they used L-Acoustics’ Soundvision 3D acoustical simulation software to precisely map out the sound field. “That kind of predictability is critical for a loud outdoor show like this.”

Atop each main array were four K1-SB high power subwoofers per side. “Flown subwoofers were the key to being able to overcome the unique bass null that was created by this sort of concrete moat area in front of the stage,” he said. “It was an architectural challenge that we were able to overcome with the right speakers.”

Along with a total of 32 SB28 stacked subs, the Live Stage had all the low end it needed and then some. In addition, two ARCS II constant curvature line source loudspeakers were used as side fills under two SB28 subs per side; six ARCS Wide enclosures were deployed as front fills; and, finally, 24 Kara enclosures were used for outfills.
