Tiny Planar tweeter test. Yes also music for those that care

I wanted to see if i could get rid of the cavity resonance by using different metal and some neodymium magnets. so far so good. one weird dip at 4.5 Khz but i think it is the width of the membrane... which is 4cm exact half a wavelength around 4.5 khz. so i might make them bigger add a few rows more and divide the membrane into 2 or 3 sections. also i am going to etch one (with a laminated foil) see if it performs as good, since adhesion on those foils is better then i can glue.
