Hi Grant, you would need to contact Involve Audio or ER Audio directly, links are in the last section of the article.

Enjoyed the article !
The last picture of the ESL speakers looks very much like Solo Static which I own.
Haven’t setup my HiFi back again.
Lost my PreAmp Audio Research SP5
My set up was:
Audio Research SP5 with AR End Amp class A, all tube for my Mid range ESL
2x Quad 405 (mono block 100watts)
2x Nakamichi filters for Sub woofer and Tweeter.
1x Tube amp Ampliton to drive my Ionefane flame tweeters.
Interlink with Silver cord cable.

I once tried Dynacord ESL which sounds nice on modern music, more direct and agressif. But the QUAD is much smoother & natural especially for classic music.

By telling all this, where can I listen the speakers on your article ?
I would like to hear it some where around Amsterdam or in Germany around Münster please.

Hi John, re availability you will need to direct your query directly to Rob or Charlie, see website links in intro. On the question of satelite speakers, I think you’ll find they need a woofer underneath each, they don’t really go low enough to cross directly to a sub.

Are your small electrostatic panels available in the United Kingdom and could they set up as five “satelite” speakers in a Dolby 5:1 system?

Cheers

John.

I have just bought a pair of Nakamichi Dragon HDA electrostatic speakers, can you suggest a source for an instruction manual please? Regards, Rick

Hi Rick, I’m assuming these questions are for Charlie and Rob? It would be best to contact them directly (contact info on their websites). Did you have a specific application in mind?

Sounds damned appealing

To be realistic about likely limitations, three questions please:
“THD: < 1%" is a little vague but highish, and THD doesn't correlate well with hearing. How is the audible distortion vs other ESLs (commercial) that many of us have heard, eg Quad and Martin Logan?

If crossed say at 250 Hz with a 4th order, what is the maximum power handling and in particular the maximum SPL, while still keeping distortion low enough for that ESL "magic"?

What is the – 3 dB angle of vertical dispersion?

Cheers
