It'll be interesting to try the "mechanical segmentation" on the diaphragm to see if it makes much difference on the bass response. Perhaps, with those little round spacers, the tension on the diaphragms can be made much less.

Why don’t you want it?

Very nice! Just take your time. It’ll be a fun journey for you.

Go for it!

Have you every tried using ABS instead of PETG? I find PETG is too flexible.

That should work! Thanks for sharing.

Your headphones look really nice! Please share with us more when there is any progress. I want to mention something about the dust covers. It's fine that you have a dust cover that is as tight on the surface as the diaphragm if you only put it on only one side of the driver. Putting tight...

It’s best that you read through the thread. You’ll learn a lot. Anyway, I normally spray the coating on a piece of lint free cloth and simply wipe on the diaphragm. I wipe it a few times to make sure that I get an even coating everywhere . After it’s dry I gently buff the surface to get an...

I have tried rubbing the graphite on the film before. It’s OK. But after a while the resistivity gets much higher and eventually fails. I think the graphite loses its adhesion after some vibrations of the diaphragms. Try using the car detailing product containing graphene. It’s very easy to...

Hi and welcome! About your questions: 1. the resistivity on the diaphragm should be very high (higher is better). The coating I use has the resistance of more than 1 G ohm. But, anything of more than a few hundreds of M ohm should be good enough. 2. About the stators, using anything that is...

The weight and comfort of DIY electrostatic headphones can be done to your own liking. All my headphones are very light and I can listen to them a long time. 3D printed housing is also a good idea.

The reinforcement on one side is enough. That’s how Stax has done. I think anything that is strong enough is OK. 3D printed parts is a good idea.

Yes, you definitely need the extra reinforcements.

Have you ever listened to the original SR-Omega? Its sound stage is huge! The diaphragm is 90 mm while the stator is around 80 mm. Of course, the stators are wire meshed.

Bigger driver area tends to give a bigger soundstage. As for the different hole sizes, I hear very little difference.
