Adamson Shines At Riot Fest In Chicago, Toronto and Denver

December 2015

Riot Fest, a three-day, multiple-stage rock, punk, alternative and hip hop music festival used a sound reinforcement system featuring Adamson loudspeakers.


The 2015 lineup included performances by Billy Idol, Iggy Pop, Motörhead, CIV, the Damned, Ice Cube, and even country music legend Merle Haggard.

Kansas-based StagePro was tasked with providing production services for all three events. Omaha, Nebraska-based Audio Visions provided additional sound reinforcement support. Audio Visions deployed their Adamson E Series PA at one stage in all three locations.

Jasper Goforth, General Manager for Audio Visions, explained: “When we purchased the system we were looking for a PA that would keep us on the cutting edge, it’s events like these when you want to make sure that you are providing artists with the quality they expect. The Adamson rig has everything we could need and it really delivers for performers.”

Although the specific stage and performers varied from location to location, the sound requirements stayed fairly consistent. Goforth originally input the stage dimensions into Blueprint AV, Adamson’s predictive simulation software, and then would add the scope of the audience area that required coverage in each city.

He added: “We were really blown away by the Blueprint software, it is incredibly accurate. We were used to using software that still required a fair amount of tweaking once the PA was hung. Blueprint is spot on every time. It’s a tremendous time-saver.”

The left-right line arrays, made up of 12 Adamson E15 and two E12 enclosures, were hung from an APEX 5040 hydraulic stage to the left and right of the stage. A total of 16 E219 subwoofers provided low end. Six were ground stacked under each array with another four up the centre.

Two Adamson S10 enclosures were placed along the lip of the stage for front fill. Four E119 subwoofers were utilised for side fill subs while another two were deployed for drum subs.

Both the Adamson E15 and E12 are three way line source enclosures. The E15 is loaded with two seven inch Kevlar Neodymium midrange transducers paired with two four inch high frequency compression drivers while the E12 features a single seven inch Kevlar Neodymium midrange transducer paired with a four inch high frequency compression driver.

Enhanced low end is provided by two 15 inch (E15) or two 12 inch (E12) proprietary Kevlar Neodymium woofers.

The system was powered by racks of Lab.gruppen PLM amplifiers. Goforth added: “The Lab.gruppen amplifiers, which Adamson recommends with their loudspeakers, are terrific. They are clean and drive the system without breaking a sweat.”

He noted that as they moved from one location to the next he noticed that the Adamson rig was getting placed on more “featured” stages. After inquiring why, he was told that the engineers on the other stages heard it and asked to use it on their stage.

Goforth concluded: “I have to add how impressed we were with the entire Adamson team. We are not a huge house and knowing that we would get the attention we needed from the manufacturer was a big plus. Everyone we worked with was knowledgeable and anxious to help. I think we’ll reap the rewards of this decision for years to come.”
