    ESTA 4u inside

    Ah, you have one kit for one channel? I see why you didn't do so much with it ... And true, only simple baffle for one driver should be enough + some quick driver, did you consider Accuton? I have speakers with midbass and high from Accuton - for me the great drivers, and really quick for ESL.

    Open baffle for computer with small box at the bottom for electronics and maybe some little RIPOL (I have no idea if RIPOL can be made such small). But this is what I'm thinking about. Those Stax speakers are to wide for my bench 😞

    ESTA 4u inside

    The open area (I mean the window where stators are open to outside) is 161x92 mm The one stator is 104x171 mm (50x171 mm one part, mind the gap in the middle between stators in one driver).

    I don't have any measurements except Stax data on picture. What is the biggest surprise? This is 3 way project ! There are two diaphragms but 8 stators. Looking from the back of the speaker: the left driver is full playing bass and lower mids. The right driver is two way system. The very right part is playing bass and all mids. And the second part is driver with full signal from transformers.

    ESTA 4u inside

    Hello I had a chance to buy two pairs of Stax ESTA 4u speakers. Both pairs look nice, but all four had imbalance issue and I decided to check what is inside and if I can repair them. As you can see, drivers are easy to open. The disintegrated foam's particles got into drivers and stick to the diaphragm (foam was layered with some glue). I had to clean it all from this and use Licron on diaphragms (I did that only with one pair atm). Now the one pair works well, bas is not so strong, but it is enough to work with some active sub. The stereo sweet spot is really thin, but when you seat in the right place the image is sharp and precise. I'm thinking about rebuilding the second pair, but to use drivers to make custom speakers, rather tall, just to use it as computer speakers. Naked driver.

    I was testing some KingSound - I didn't like them too, dark, flat, lifeless. Any Stax, even SR-3 are better. What kind of mods did you make to the KingSound??

    In my opinion it has a detachable cable, but it's just an opinion ;-)

    I wonder what happened? Do we have any others pics and any informations?

    Well done Arthrimus

    It is possible. I have recoated two pairs of old Lambda Signature and they work fine. There is a risk of breaking mylar as I did for the first time, when I was opening driver. But any other try was without issues.

    Small amplifier for Stax

    JimL - I hope now that you won't call me "heretic" when I publish my amplifier with tubes and chokes I read your thread about using current sources and driving electrostatic headphones. Very interesting, thank you.

    Small amplifier for Stax

    JimL, thank you for your detailed explanations. I promise to search and read the thread you proposed. I know how CCS works, and I agree with you in fundamental rules you described. I build others amplifiers with CCS or resistive and I don't want to build another the same topology's amp. When you decide to build tube amplifiers there is a space for many imperfections. In your eyes my decisions of using chokes is technically wrong. And you are right. For me it is just another way. Is Megatron with it's CS on EL34 technically better than KGSS? I bet it is not, and that proves nothing, as Spritzer would say

    Small amplifier for Stax

    JimL, do you suggest that electrostatic headphones should be driven from high impedance output? Can you explain why?

    Small amplifier for Stax

    You don't have to be so cruel It is possible to build something good even if you don't think so. Did you build an amplifier for electrostatic headphones with power stage with choke?
