Full-range, two-way ESL

This Hale haunts me, only with these two ESL packages:

I’m a modest guy and I don’t need that much, maybe I could lend it to someone?:

There are several changes to the current state of the audio system.
Firstly, I finally got rid of a couple of parasitic resonances in the mid-bass register by installing a memory form tape on the back of the bass segment, it divided the radiating panel at the back into two equal parts, I don’t know how this affected the destruction of the resonance, perhaps due to the physical size rear panels 50/50cm. divided into two 20 cm each.))). In general, this is an empirical decision, not fully realized.

Next about the amplifier, I received from the author of the product two new modules with an output load impedance of 1 Ohm, which I needed for RF drivers.
This guy also developed new power supplies specifically for these amplifier modules, previously I used Chinese ones from Aliexpress, they were too noisy and got incredibly hot, for them I made a huge battery of cooling radiators, now, with the new power supplies, the radiators are completely cold, now they are serve as decoration))).

As for the connecting cables, I made all the connecting cables, starting from the head of the vinyl player and ending with all the rest, from mono strands of silver of the highest standard (999.9%) and screened everything very high quality, I bought the silver in a specialized store for jewelers.
The sound with noble silver is absolutely clear and realistic, it immediately caught my eye.

Did you try this subwoofer with additional flat baffle (I think, at measure, bigger distance)?

Of course I tried, I put a spacer between two packages (each with 3 membranes and 4 stators), with a distance of 10 to 20 cm, and even made the effect of a slightly open book (here it is at the beginning of the thread), then I was looking for how to get rid of the pronounced resonance of 136Hz and its highest harmonics, I even bought a parametric equalizer then to accurately influence this frequency, but the equalizer was digital, and I listen to analogue as well, and this was a contradiction .
Next, I looked for how to empirically get rid of parasitic resonances and slowly began to feel for it and yes, I continue to do so.

I measured my speakers, did it twice, the result is almost the same, something is unbelievable.
I made the same measurements of electrostatic headphones, in them 0.17%.
