Default Audiostatic ES 100, mylar replacement

Hi,

I bought a used pair o Audiostatics, and after a good clean (tried to remove the disposed dust) they sound fantastic. I m a huge panel enthousiast (as you see )


Click the image to open in full size.



1. I would like to ask you how i can get the side wood pieces off (left and right of the panels). (i managed to get the top and bottom screw-fixed pieces off, but i cant get the sides off).


2. Where can i buy suitable mylar from? (please i need to buy the mylars from an internet supplier - also, whats the preffered thickness i should ask for?)

3. any pictures for mylar replacement would be very-very helpful as well as any advise/directions.


Thanks for your time, i NEED your help

Hi audiostaticproject,

are you sure that you need to replace the mylar ?

To get appropriate mylar is not an issue, but to proceed the mylar the riight way.

Do you know how to tension the mylar on ist length and width, do you know about possible thermal treatment, do you know about the required coating ???

There is a certain potential that the replacemenet will end up in big frustration

Capaciti

so,


1. how can we tension the mylar and how can we thermically treat it ?


2. what kind of coating is required?


(have you ever done it and ended up in frustration?? - what are the mistakes that should be avoided? )

please provide technical advice and photos, changing the mylar is not rocket science

has anyone done it before ?


thanks for your time, answers needed here

It seems you don't need any replacement at all as they sound fantastic.
Do I miss something?

No rocketscience, more like black art...

ok, they are playing fine, but you want to improve.
Putting 4 micron instead of the original 6 micron will give you slightly smoother sound, but only if you can do a good job in replacing the Mylar which is not obvious as capaciti already has pointed out.
It will be easier to improve electronics. Play around with the input cap for example.
With luck you might find the old mirrordrive electronics of audiostatic es200/300 models. Putting this in the es100 might solve the anemic bass issue and give them a more warm end pleasant sound which will be immediately clear in A/B comparison
Replacing the trannies with expensive amplimo's might give you something although I didn't try the latter, just what I heard from other persons.
Some persons are specialised in improving audiostatics , for example Audiofinesse, if you live in the Netherlands.

Hi audiostaticproject,

maybe you think i am crazy, but in the last 20 years of developing fullrange-ESL i learned a lot of lessons about the amount of different parameters when tensioning mylar for fullrange -ESL.

I know exactly how limited a wrong treated mylar can sound. Thats why i recommended not to do so.

But ist not up to me to compromise your enthusiasm.

Try it, but be careful, the first problem will come up, if you try to pull the sides away. The ESL frame is glued into the sides with silicone. By 80 % you will crack the aluminium crossbars of the ESL and than thats it.

I know this is not the answer you are looking for (and you're probably going to be upset) but I'm going to say this nonetheless.

You clearly do not have the expertise to do this, otherwise you would not be asking these (rather mundane) questions. Actually it's kind of arrogant to think that you can improve these speakers by just slamming on a new foil, without having the slightest clue what you are doing! Most ESLs are fine tuned devices that require craftsmanship and knowledge to perform to their best.

My advise: leave them alone or bring them to an expert. If you want to learn, start browsing this forum and build your own ESL. That way you don't have to destroy a pair of good speakers while you are learning.

I hope you'll forgive me for being blunt.

Hi Audiostaticproject,

If I were you, I would leave those speakers alone. If you want to learn, make yourself a new pair might be easier.

About the suppliers of Mylar, you can find them easily on the internet. Ebay.com has it. Eraudio.com also has it.

About the coating materials, there are many types. You can try the DIY recipes or you can buy them from a few suppliers. For DIY versions, Favorite Threads and Posts in "ESL's, Planars, Alternative Technologies" Forum .

Again, if I were you, I would build a new pair and leave those beautiful ones alone.

Good luck.

Wachara C.
