Avante Audio’s Imperio Pro loudspeaker system supported a Katchafire concert for approximately 3,000 people at Vidinha Stadium in Lihue, Hawaii, according to an account published by the manufacturer.
Kauai-based Audio Visual Technology LLC provided audio, lighting, video and backline production for the concert, which also featured Hawaiian acts High Watah and Revival. Company principal Kent Tanigawa designed the audio system around Avante’s compact IMP205 line-array module.
The main system used two flown arrays of seven IMP205 modules per side. Two more modules served as stage fills, while two delay towers carried four IMP205 enclosures each. The configuration placed 24 IMP205 modules across the main, fill and delay positions.
Low-frequency reinforcement included one Imperio Sub 210 flown with each main array, eight ground-stacked Imperio Pro IMP118 active subwoofers across the front of the stage and four additional Sub 210 units at the delay towers. Eight Achromic A10 active loudspeakers handled stage-monitor duties alongside Katchafire’s in-ear monitoring system.
Tanigawa said he first heard the original Imperio system at the NAMM Show and later expanded Audio Visual Technology’s inventory when Avante introduced the Imperio Pro version. He said the compact enclosure’s portability and scalability allowed the company to assemble a system large enough for the stadium concert while retaining equipment from the original product generation.
The delay towers were positioned about 250 feet behind the front-of-house mix position to extend coverage into the rear concession area, Tanigawa said. He described the design as having adequate headroom at front of house while maintaining coverage for listeners at the back of the venue.
Avante specifies the IMP205 with two 5-inch neodymium low-mid drivers, six 1.75-inch high-frequency transducers, Class-D amplification and onboard digital signal processing. The manufacturer lists maximum output at 128 dB SPL. The companion IMP118 uses an 18-inch woofer, while the Sub 210 employs two 10-inch drivers in a bandpass enclosure.
The company lists the IMP118 with a 4-inch voice coil and frequency response extending to 32 Hz. Avante describes the smaller Sub 210 as a sixth-order bandpass design with onboard Class-D amplification.
The deployment is a practical example for dealers and integrators serving regional production companies: a compact powered system can be expanded across main arrays, front fills and delay positions while keeping the same loudspeaker family throughout the venue. It also shows how a supplier’s product line can cover mains, low-frequency reinforcement and monitors within one production package.
Audio Visual Technology also supplied fixtures from Avante sister companies ADJ and Eliminator for the event’s lighting system. Photographer Sheadon Ringor documented the production.
