I didn't make it to the 2nd video before and it's indeed interesting.
Esp. how he describes the result of his trick: "addition of HF transforming into more air and resolution in the MF instead of more glow at the top"
(around 2:30 at the video). It's somethig I'm fighting with in my context now.

This guy does not say anything new. It is just a reiteration of the notion that has been pitching for years: HF shall not be reproduced by efforts of HF channel but by via transient capacity of MF channel.  The question is HOW we doing it.  I use compression drivers as I feel they have minimum excursion and max sensitivity to minimum currents.  He drives 200 drivers and get very high low current sensitivity and practically no excursion from each drivers, setting each driver to very optimum magnetic and mechanical configuration. His way however in my view creates absolutely absurd lobbing, comb filtration and many other problems. If he run a pulse response across his 200 drivers it will be nightmare, I down that you even see the pulse.  There is an interesting moment in what he does however. If he has 20 drivers then I would say that it was damn but he runs 200 drivers and they are not in array and not organized in any inelegant way. They are just randomly thrown and I am not even sure if he set them to run in phase. So, it is “possible” that with that bizarre amount of drivers the system sort of randomizes the phase errors and act as some kind of phase dither. His pulse in that case would be a pulse cloud and it “might” be interesting. It is hard to say anything as I never heard that indiscriminately set 200 drivers and the results they might produces.
