ESL Headphone

[rendoman]

Hi all!
I'm trying to build a couple of electrostatic panels for headphone.
I'm reading a couple of books and opinions in internet about the right "rule" about size, polarization and materials.

I'm building frames for stators and diaphragm from 10mm PVC bar.
I'm not sure about type and thickness of diaphragm, normal film for food should be polietilene or pvc about 12 micron. Someone in audio forum tried 1 micron film with very short distance from dia to stators.

I tried first frame in thin lexan, but it wasn't good, too flexible!

Here a picture of Esl operation





Here the good frames in PVC





Here the bad old frame, I made a wrong choice with the not perfect wooden plank
