Karol Zieleźnik has run his audio store continuously since 1991. He is a respected and well-known person in the Polish audio industry. Moreover, he is an audio hobbyist, who is independent and resistive towards trends. In his store, he simply offers only the best brands. He has been promoting Polish products and supporting Polish manufacturers for a very long time.
For a couple of years now, Karol has been organizing Audiofil Design, a local show taking place on the occasion of Lotos Jazz Festival Bielska Zadymka Jazzowa.
The idea of establishing the Polish Audio Cluster had been maturing for a long time and it came true in 2014. We wanted to take an example from similar clusters from other industries, hoping that it would concentrate valuable Polish companies and becomes capable of competing with large brands with regards to an image.
