Maybe It should be "Like" piano wires instead of with piano wires!
Cause this looks like a flat metal plate that has been perforated with slots instead of holes.

Just my

Hi,

Steel wires are called "piano wires" ("corde à piano" in french) :

These electrodes are made with ø 1.5 mm steel wires.

it is from piano wires I assume it must be. I suppose you could braze them(hard silver
solder used in jewelry making) but this would heat up the piano wire to a point that it
would change it's properties. I think they could also be wound around a stator plate like
a bobbin and then plated but it doesn't look like this is what has been done here.

Hi Vaughn,

I used 1 metre long straight steel wire cutted in small pieces. It's very hard to make flat electrodes. The electrostatic cells are also a bit heavy.

Hi Wachara I' m inspired to build my own phones after reading all the posts here. I'm also interested in direct drive and found Kevin Gilmore's designs at HeadWize the most promising. Anyone try them out? My first post, not last.

Very interesting thread I have always wondered why so few took on this task.

Hi thinkbad,

Here is the thread of Wachara, about DIY electrostatic headphones but, indeed, my ESL speaker also uses "piano wires" in trapezoid electrodes plates.

Best regards

Philippe

I'm also building a pair of ESL speakers, please share with us your experience.

Try it. It's the only way to find out.

Hello All, Can anyone share comparisions, diy cans vs. the big $$. Convince me and I will roll.

How would you like to be convinced? All of my friends who have listen to my DIY version want one from me.

We had a meeting a few days ago, and we had a Koss and a Lafayette to compare with our 3 DIY versions with different Mylar thicknesses. All of our DIY versions sounded much better than the 2 brand name ones. Well, it's just our opinions of course.

For me the fun of DIY is not to make the best, but to be able to try what we want to and see if they work.

Hi Wachara, Point taken on the fun factor

Ahh my old Koss, sounded like hell calling with my first kit on the front end (dynaco pat-4). Thanks for sharing

I love that picture Wachara, I wish I could have been at that meeting!

I am undertaking my own electrostatic setup and will post pictures as I go. I have owned quite
a few nice dynamic headphones(Grado RS-1, Sennheiser HD-650, AKG K340(hybrid), Denon AH-D2000, etc) but my favorite headphones (earspeakers according to Stax) so far have been the older electrostatic Stax Lambda Signatures(better than SR-404). I am looking forward to building this and wish I still had the Stax to compare it to. You really can't beat an electrostatic for beautiful transparency and they have the capability of delivering excellent bass(think of all that surface area!).

Wachara, maybe you could start a new thread on the electrostatic panel you are building once
you have it to a point that you feel comfortable sharing it with others? I am thinking about the
possibility of building a hybrid speaker with MJK's 18" open baffle Goldwood woofer for bass and an electrostatic panel on top. I don't know if these would have good synergy but half the fun is finding out!
