“I had the pleasure of testing the M-F3A Pro and S15 Pro from you. The system easily covered 400 people open air. It works very good on far distances – even after 50m – thanks to the angle of the individual elements. I had 3 subs per side in a cardioid line-up – that was more than enough for the lowend … What particularly impressed me was the clear intelligibility of voice and singing over such a long distance. I hope we have the opportunity to test extensively again.“
