I use this system for about 7 years for orchestra (four five musicians). (Ict300 in head and ics400 in subwoofer.
I normment meeting concerns regarding the Lower Rumbles, on stage.
But I use a Qualizer but when you fall too serious, they will become non-existent in the front and continue to turn as the rear of the stage
Someone would have a solution to correct this default?
