While original plans set a capacity of around 33,000 seats, this was later upgraded to 42,276 seats
Turkey - When Konya was under consideration as one of the host cities for a future European Championships to be held in Turkey, construction of a brand new UEFA-compliant stadium was proposed.

While original plans set a capacity of around 33,000 seats, this was later upgraded to 42,276 seats - divided over two tiers, with an additional 50 VIP boxes - and the new facility, based in Sel├žuklu, will now provide the club Konyaspor KR with a state-of-the-art stadium for home matches.

Asimetrik, the Turkish-based distributors and AV system integrators, were awarded the contract to provide a network-based professional grandstand PA system, as well as broadcast infrastructure system, not only compatible with UEFA requirements (but also FIFA and IAFF). They also designed and supplied a PA/VA emergency evacuation system, C.I.S. infrastructure as well as full conference and visual presentation tools for conference, press and meeting rooms. All design, supply, installation and commissioning were undertaken by Asimetrik, who turned to RCF's Acustica H Series as their primary sound source.

To ensure such seamless acoustic design and installation, Asimetrik worked alongside main contractor, Saridaglar Construction Company and engineers from the Konya Municipality from the very beginning to design a seamless acoustic environment. Led by their project manager, Burak Bayrak, they designed a number of unique solutions, using EASE Simulations to visualise the optimum distribution of sound to the seating areas, using the predictive software to set correct splay angles of the RCF loudspeakers and predict the performance with absolute precision.

Turker Baran, Asimetrik's acoustical design engineer, and Burak Bayrak knew that the RCF solution was a proven model, having been inspired by the installation at Juventus Stadium in Torino. "The H Series is also a perfect fit for this stadium - in terms of both power and dispersion," says Mr. Bayrak. "RCF's technical project team partnered us to design the system for Konya. RCF is a unique and well-established brand with a very strong history, and as a partner for 14 years we are delighted to be their distributor."

RCF Acustica H1315 WP loudspeakers were used for the network-based professional grandstand address system. Asimetrik specified 96 pieces of RCF Acustica H1315 WP loudspeakers, a three-way full range loudspeaker that incorporates a 15" LF transducer, a 10" cone MF transducer and 1.4" exit titanium compression driver. These are mounted in double clusters across 48 rigging points, with a 12m distance between each cluster.

"Designing a system which is fully compliant with UEFA standards was very complex, but the RCF products were exactly what we needed to make it work," concludes Mr. Bayrak. "The RCF H1315 sounds quality is superb and the system is extremely compact as well. A number of matches have already been played and we have had very positive feedback."
