First video of MFB correction on a planar magnetic driver

Well so much to try :) this is the first video of a planar magnetic and the use of the circuit.. there are some points that are crucial to get the best out of it, those are foil needs to move as one as best as possible... now this is not easy. the more coil over the entire foil the more even it moves, but its also in small tiny things like, at some places having more holes behind the foil (open area) witch can damp parts of the foil and the correction wont be working there.  and the fact a foil does not move like a stiff plate but more like a drum. so it moves more in the middle and less on its sides.
