test planar magnetic tweeter 9 12 or 25 micron alu ?

well i did a small test. thick alu foil or thin?

conclusion for me is the , the less they go towards line source the thicker the foil. to compensate for increasing top end.

And here is the heaviest foil playing music in my mini monitors. i must say that 4Khz distortion peak that i did not fix here is rathert anoying combined with the 8 Khz peak of my audio recorder, well anyhow fun song :)
