The audio system was designed and installed by Warsaw-based Tommex Zebrowscy Sp. J., and completed in September 2010. Within the main stadium, the system consists of nineteen Community WET W2-2W8T for the East, West and North stands. The largest stand in the South uses fourteen 90x40 degree R1-94Z loudspeakers, configured in seven clusters. A further three R1-66Z, this time with a 60x60 pattern, cover three corners of the stands and two R2-474Z cover the playing field. In addition, four Community RSH-462 systems are utilized for the public areas around the stadium.
