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.

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.
.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.
Did some more experiments and measurements.
Manipulations with a piece of plywood, which I put in different places of the bass driver led to the disappearance of a couple of parasitic resonances, which was indicated by measurements in the listening position on the sofa, because the microphone was installed on it, and not in one meter or 30 cm from the driver itself. Although this search lasted long enough, as I wrote here I even tried to apply different equalizers (graphic and parametric), but eventually abandoned them completely.
At the moment the signal from the sound source goes through a Canton preamplifier, an active crossover (two-way) and a class "D" power amplifier.
I will say a few words about the safety of electrostatics, although I was warned by the moderator of the forum (in connection with the rules), that if I once again raise this topic it will be the last time, then apparently he will ban me forever, but still I will raise this topic.
What the user of electrostatics(?) needs to know is that you can touch one stator with your hand if you are on an insulating material, that is, if you are standing on a wooden floor or some other floor that is not directly connected to the Earth.
It is also strictly forbidden to touch two stators located at the front and rear of the driver at the same time.
Since I have dealt with electrostatics not theoretically, as many here, but practically and built them for 12 years, I make this statement responsibly, as well as demonstrate it on the video clip, which in one of the topics here on the forum moderator deleted as life-threatening. But listen, so it is possible to come to the fact that ban sockets for electricity, there is also high voltage and if you stick two fingers in the socket, it may not be good, so we need to know what can be done and what can not be done.
The frequency response graph shows a rise in frequencies in the region of the main resonance of the room, as well as in the region of the highest frequencies (18 kHz), since the microphone is installed on the sofa where I sit while listening to music, then my calculation of a vertically curved HF driver whose sound from a distance works here does not get lost, as in a conventional driver, but rather focuses and comes to the ear without loss.
Let me remind you that the HF driver is curved with a radius of 3 meters and this is exactly the distance from the driver to the seat on the sofa.
I am attaching a photo of a toroidal step-up transformer made in the village of Velykye Kurylivtsy, Vinnytsia region (Ukraine), I gave them technical specifications and they made the first ones back in 2012, then I ordered the same ones from them several more times, they turned out to be very successful for the bass driver (transformation coefficient 1:200)
