Hmm. Thanks Spritzer for your input. Let me try. If it's no good, it's pretty easy to change it later.

You could always try it by placing it behind any of your other sets and see if there is any difference.

Hi Spritzer,

 

I've tried what you suggested by placing the plates at the back of my Orpheus.  What I noticed was a little (very little) change in sound stage.  The bass wasn't affected at all.

 

I intended to etch out the unneeded copper on the stators yesterday, but was too lazy. tongue.gif

That's good to know but one can never be too careful with the backwave reflections.  One of the precursors to the Jade used a slotted backplate such as that and it was panned for sounding very strange indeed.

Amazing job :)

The new ear speakers are now singing.  beerchug.gif

 

 

 

 

I use 0.5 mm spacer and 3 micron Mylar.  The bias voltage is 580V. 

 

It was very late last night when I finished it, and I only had just a short listening.  Overall, the ear speakers played plenty loud.  The amp I used was eXStatA with my iphone as its source.  Playing songs at 1 o'clock volume was more than I could bare.  There was still some noise in the right driver, and I wll fix that tonight.  Will update again later.  beyersmile.png

Did you have a frame rigged up, or were you just holding those speakers up with your hands? 

 

Looking good!

At the moment, I'm holding them by hands against my ears. I'm still thinking of a good way to frame them up. frown.gif

With earspeakers that large you'll get tired quickly! duggehsmile.png

Thanks.   Just so you know, Playing them using a KGSSHV or DIY T2, they can be a pair of good desktop speakers too.  beyersmile.png

How do these speakers/headphones handle their resonance? I thought free standing speakers had to have two panels, one bass and one treble with intentionally non-overlapping-resonances. And it's no different being headphones with no seal. The FR must be atrocious!

I don't think he meant speakers of reference quality.  Still if you mount them in a fairly large baffle then the sound would be ok.  Maybe some light damping on the back end would help with reflections.

Hi Dude_500,

 

Just as Spritzer said, they weren't meant for full range speakers of reference quality.  All I wanted to point out was that they were able to be driven easily by a good Stax amp.  However, I really think that that if you can bi-amp them with a seperate subwoofer, they can be pretty good desktop ESL.

But isn't sitting on your desk or suspended an inch away from your ears with no earpads or damping practically the same thing? I know every electrostat I've ever made sounds pretty bad when held an inch away from sealing
