‘This Is No Typical Arena Act’: How L-Acoustics K2 Shaped Twenty One Pilots’ Icy Tour


September 28, 2022

In support of their award winning 2021 album Scaled And Icy, Twenty One Pilots’ current ‘Icy Tour’ is making its way across North America with an L-Acoustics K2 system at its core.

After an extensive European festival run earlier this year and the duo’s international Takeover Tour in late 2021, the band’s ‘The Icy Tour’ is on its second North American trek. Clair Global has been serving as the artists’ touring sound reinforcement provider since January and is carrying an L-Acoustics K2 system for the current arena run.

“I’ve worked on a number of K2 systems in the past and have really enjoyed their tonality,” said Kenny Sellars, who has been with the band since 2016, first as a systems engineer, then taking over FOH duties in January of 2019. “Twenty One Pilots’ show is significantly more dynamic than a typical pop-arena act. The band uses a plethora of instruments, and the show varies from moments of EDM-like bass and heavy rock to quieter ukulele and piano-led pieces. We needed a system that offered us high fidelity from the quietest to the loudest moments night after night. The sound of K2 combined with KS28 works really well for this show.”

Clair Global systems engineer Christian Peterson also commented. “I joined the tour just as they started the European festival dates in May,” he says. “During that time, I got to hear the show on a wide variety of systems and really enjoyed working on the K1 and K2 rigs we encountered. Kenny and I discussed a system for North America, and the initial designs we drew in Soundvision looked like they’d be ideal, and they have been.”

The tour’s loudspeaker system features left and right main arrays of 18 K2 with 14 additional K2 per side as out-fills, plus 15 Kara II on the 270-degree hangs. Low-frequency reinforcement is supplied by six KS28 hung per side, paired with 14 more ground subs, grouped in seven stacks of two with both a rear and front-facing enclosure in cardioid mode for directionality control. Furthermore, six Kara provide front-fill while four A10 offer utility-fill where needed.

“A big contributor to the coverage success we’ve been able to achieve on this tour has been K2’s Panflex feature, which gives us a lot of versatility,” Peterson added. “I’m able to widen or narrow the coverage of the main and side hangs to perfectly suit the audience areas, which has assisted us greatly in some difficult venues.”

He also noted that the quality of the predictions in Soundvision, predominantly due to the software’s Autosolver tools, ensures a quick process each morning for system design.

“Once I’ve confirmed the venue dimensions with our tour’s rig plot, Autosplay and Autofilter give me confidence in the system’s deployment, which is then verified during the optimization process and my walk of the venue. We’ve also adopted the P1 processor, which enables us to utilize useful M1 measurement functions, including Autoclimate for temperature and humidity compensation.”

“I’ve worked on all of the major systems available, and while each is capable of producing a fantastic representation of the mix, how quickly and confidently I can access these tools and enable decisions is what sets L-Acoustics apart,” Sellars said. “The features available in LA Network Manager, such as Zoom Factor in Array Morphing, have given me the ability to make faster changes for what I’m after in the arrays.”

“We’ve heard some great comments from audiences and colleagues on the sound, particularly on the extensiveness of the low end in certain moments of the show,” Peterson concluded. “Tracks like heavydirtysouland Lane Boy have moments of beautifully deep and forward sub, which are amazing to feel, and this system never fails to produce smiles from the entire crowd.”
