No i havent mate, dont even own one, whats that got to do with the price of fish anyway?
As i said above turning the volume knob up on the actual speaker and then turning it down on control panel seem to have done the trick(apparently when you turn up the volume it makes the built in amp filter out "noise" better) clearly thats whats happening now as i havent heard any strange noises since
Im just abit

because you shouldnt have to faff around like this, why aren't the speakers made so that "noise" doesnt happen or is so faint you cant hear it
