You might want to check out Jazzman's symmetrically electronically segmented wire-stator ESL's. They are approximately the same form-factor size as Sander's hybrid ESL's but use a ladder array of resistors to turn a flat ESL panel into a "electronically curved" panel.
The center of the panel runs full range and each section further away (left and right) from the center has more and more of the high frequency attenuated. This supposedly gives you a wider sweet spot and better off-axis response.

I think this is very similar to the way the Stax F81 and F83 work.
I don't know if this design addresses the issues with 'wide dispersion' that Sanders warns against.
I am pretty happy with the imaging and transient response of the Stax speakers. But they are extremely difficult to drive.
Stax uses a bi-lateral resistor ladder array to electronically segment their their stators ?
Something like that. Maybe kentaja can verify.
Thank you. Brilliant conception.....Wonder if they are still being built by JAZZMAN.
He never built them for sale.He shares his designs freely and built those sets for his friends.
He said he will not build any more.
