Pirx

In my opinion the direct sun light means direct UV that is degrading many materials. I think that plastic dust cover is not transparent for UV and it means you shouldn't worry about it. But probably more dangerous is heat from sun light. If you do not have windows with infrared filters on the glass (for example I have), it is better to place Stax in the shadow.

Really nice looking stands. At this moment I have Quads ESL63 and I have no more space for another pair of speakers ? But I maybe I will give a try them stacked Do you know that section with highs are on the opposite side when you flip speakers upside-down? For sure the holographic can be better if speakers are in mirror. I have rewired them and the effect is amazing !!!

No video ? why?

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 ?

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.

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 thi

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.

Picture from show in Warsaw (the same where Padam was.): In short, old Orpheus still rocks

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.
