Poland’s four Euro 2012 stadia take in the cities Warsaw, Gdansk, Wroclaw and Pozna, forming an uneven quadrilateral shape around the centre of the country. For those travelling from Western Europe, it’s probably fair to say that, of the two host countries, Poland is probably deemed as being slightly more accessible. It’s popularity as a tourist destination has benefitted hugely since it entered the European Union (EU) in 2004. The volume of low-price airlines flying into the country has aided this growth. Local Harman partner, ESS Audio, secured the contracts for three out of the four stadia. The trio includes the National Stadium (Stadion Narodowy) in Warsaw, Gdansk’s PGE Arena and the Municipal Stadium (Stadion Miejski) in Wroclaw. ESS Audio’s Witold Karalow spoke to mondo*dr about the individual projects and what it means to be so involved in his country’s participation in the competition.


WARSAW Built on the site of the former 10th Anniversary Stadium, the 58,500-capacity National Stadium will host the opening game of the competition between Poland and Greece. It is an eye-catching venue, with a retractable PVC roof that unfolds from a nest on a needle suspended above the centre of the pitch and a dynamic façade lighting

scheme. It will be the largest stadium used during the championships. Following a successful bidding process, ESS Audio was given the responsibility of specifying, installing, programming and launching the main audio system, as well as the audio and video for the conference rooms and sound for the peripheral areas. Karalow explained that the architecture that gives the stadium its uniqueness, also offered him the greatest challenge: “The catwalk hangs on steel lines that also hold the central roof section. The challenge was to take into account the weight of the speaker clusters, and balance their weight, while also considering the weight load of the flying roof and catwalk.” ESS Audio has installed 56 JBL PD5322/64 speakers. It is a precision directivity 60° by 40° full range, 3-way loudspeaker that offers high output capability with excellent pattern control and low frequency extension to 40Hz. A total of 12 PD5212/64 speakers have been used. The PD5212/64 offers the same precision directivity 60° by 40° full range coverage, but a 2-way frequency range. The main system is supported by 12 JBL PD5125 subwoofers, which is a high powered, low frequency loudspeaker, boasting two 15-inch vented gap cooled low frequency drivers in a front-loaded, vented configuration. The trapezoidal cabinet is fitted with M10 threaded suspension points. Discussing the speaker choices, Karalow said: “JBL’s PD is a great sport venue speaker. The speakers offer differential drive woofers, high power and great sensitivity. As well as a diversity of possibilities for installation and weather resistance - you can choose if you use them indoor - regular PD - or outdoor and on what weather conditions.
