Avcon is a manufacturer of full-range speakers and unique acoustic panels. The company was established in 2007, when we released our first loudspeakers. In 2009 we presented our first acoustic panels from GRAND series, which revolutionized the approach of Polish audiophile community towards the acoustics of home listening rooms. Their exceptional feature is that they are multifunctional; they possess the ability to scatter and dump sound waves. What is crucial is that the user can adjust the operating characteristics of the panels.
