Ljubljana, Slovenia | April, 2014 - In the heart of Slovenia's capital city, Park Tivoli is a lush urban oasis that is home to the renowned International Center of Graphic Arts, as well as the Museum of Contemporary History. The Park is also home to Hala Tivoli, one of the region's largest sporting and event halls.

Recently, the Hala Tivoli's 4500 seat basketball venue hosted a performance of Labodje Jezero (Swan Lake) by the acclaimed Imperial Russian Ballet, drawing a full house and numerous national and international dignitaries. Audio for the event was provided by leading tour providers Akustika Pirman, who brought in a system based on Renkus-Heinz PN-Series line array loudspeakers. As Systems Engineer Metod Komatar explains, the system was exactly what was needed for the venue.

"The Hala Tivoli actually has pretty good acoustics for a sporting arena, and it's possible to get a reasonably good sound in the room," says Komatar. "The biggest challenge is the height of the left and right seating areas, and how to cover it consistently using a relatively small number of loudspeakers."

The main system, designed by Komatar and director Joze Pirman, comprises four flown arrays — two left and two right — each with six PN102 line array cabinets. Six DRS18-2B subwoofers covered low frequency reinforcement. Four TRX151 full range cabinets provide front fill for the first few rows, with two more TRX151 boxes onstage as side fills for the artists. The system was powered by Crown and lab.gruppen amplification, with a Xilica XD4080 unit for system DSP.

"We have used Renkus-Heinz systems for many years, because they always fulfill our needs perfectly, through many different types of events," adds Komatar. "The PN102 line arrays deliver a nice wide dispersion that enabled us to consistently cover a large area with a small number of speakers. The Renkus-Heinz system proved itself once again, with a very natural sound and plenty of headroom, which is critical for classical music."
