Dream Theater Takes North America’s First L-Acoustics L Series System on Tour

Brand new L2 and L2D enclosures give PRG’s crew on the Dreamsonic tour spectacular sound combined with greater power in a smaller footprint that’s easier to carry, load, fly, and use

Originally formed by three students attending Boston’s Berklee School of Music in 1985, New York-based Dream Theater is regarded as one of the “big three”—along with Queensrÿche and Fates Warning—of the progressive-metal genre, responsible for its development and popularization. Nearly four decades later, the band is still going strong and was recently out on its inaugural Dreamsonic tour, billed as the band’s “very own prog-metal music festival,” according to guitarist John Petrucci, who adds that it will be the first edition of an annual prog-centric traveling festival curated by the group.

Dream Theater, along with support acts Devin Townsend and Animals As Leaders, was also charting new waters in another significant way. This was the first tour in North America to deploy the new L Series system, introduced by L-Acoustics in April as “a breakthrough concept in concert sound made possible through the culmination of 30 years of intensive R&D in software modeling, loudspeaker technology, and electronics.” Before the system becomes publicly available this fall, Dreamsonic’s L2 and L2D enclosures were being carried and deployed by PRG, one of a handful of pilot-phase production providers.

Steve Thom, PRG’s system engineer on Dreamsonic, says being one of the first to fly L2 is its own kind of dream. “It’s an absolute privilege to be one of the first to be hands-on with technology like this on tour,” he says, adding that L-Acoustics provided training on the new L Series before the tour and support as needed once it began.

Thom says he’s enjoyed taking the L2 into each venue during the tour, where staff have been excited to check it out. “They want to know what we’re carrying, and I get to say, ‘Have I got a surprise for you!’” he laughs. “Everybody is very intrigued about the new technology.”

He’s also been impressed by the features and capabilities of L Series, citing in particular how few boxes it takes to assemble a system adapted to accommodate all venues on this run, which he accomplishes using L-Acoustics Soundvision software. “Depending on the size of the venue, we’ll do either two or three L2 over an L2D. The largest we’ve done is three L2 on top of an L2D, but even that is far more compact and streamlined than any system we’ve used before, even K2. We don’t have to set 16 inter-cabinet angles and eight jumpers as with a conventional line array. We only have four elements to connect, instead of 16, without sacrificing any output.”

Two other new components also make the assembly process easier. The new LA7.16 high-resolution touring amplified controller, which supports L2 and L2D with 16 channels of high-power amplification and processing, comes in a new LA-RAK III touring rack offering 48 channels of amplification in a Milan AVB-ready package, with more than 60,000 watts of power in just 9U. And the forthcoming new Clamp1000, which can carry up to four L2/L2D, makes rigging simple and predictable, allowing users to rotate a flown line array from the ground, significantly saving setup time and the number of motors needed.

“LA7.16 is incredible,” says Thom. “Everything you need is integrated into a single amplifier, so you don’t need multiple amps, and the multipin connector on the back takes any guesswork out of the process. L-Acoustics literally thought of everything for the L Series.”

Thom says he’s noticed immediate sonic benefits. “Compared to a conventional line source that will most likely have one group of FIR filters dedicated to four compression drivers, each group of FIR filters on the L Series is dedicated to each individual compression driver in the line, providing increased resolution,” he says. “Also, the transition from component to component is incredibly precise, so there’s no gap in coverage, and the system’s tight directivity really helps clean up the sound on stage.”

L2 and L2D impressed many on the six-week, 29-date trek

Out in front of the system, Dream Theater front-of-house engineer Michael “Ace” Baker had his own epiphany with L Series. “It’s been exciting to be part of this,” he says. “When we go into new venues, I see staff there, who didn’t have to come in that day, show up just to see and hear L Series. That’s happened multiple times on this tour.”

Baker has found L2’s sound to be truly distinctive. He says he’s noticed that in reactions from audiences at shows who comment on the sonic quality, but also from a particular and knowledgeable source: the bandmembers’ wives, some of whom are traveling with the tour. “They’re all musicians, too, and they knew something was up with the sound right away,” he says. “They could clearly and distinctly hear greater definition of each instrument.”

“This is an awesome box,” he adds. “In each venue, it felt like it was exactly the right system for that room, and you didn’t have to wait until halfway through a show to realize that. Talking with the front-of-house engineers for our openers, Devin Townsend and Animals As Leaders, we all say the same thing: L Series truly makes us excited about mixing again.”

PRG Project Manager Randall Knight concurs that the compact and powerful new L2 and L2D were the perfect fit. “Delivering a system that meets the sonic, budget, and space requirements can be challenging when every venue on tour is so different,” he says. “We went through multiple options in the planning stages of this tour since it was going to theaters, arenas, and amphitheaters. Once L Series was on the table through the pilot program with PRG, it was the obvious choice. The coverage and sonic quality this system can achieve is truly amazing. It’s a game changer.”
