I found myself reading the intire brochure. thanks.
That's fascinating. I remember once I had this EV 18 cab and I was running The Schumann resonance at 7.83 and I just left it going for 3 or 4 days. It wasn't loud, I was just experimenting.
Then on the fourth day, my nabour came to my door and said "What is that huge loud sound you are making? it was shaking my house. I had no idea it was causing that and I told him I wasn't doing anything.he left. Then I realized and turned it off. it was some kind of harmonic build up.

Good story!
Resonance can cause a lot of "action". His house may have had thinner sheetrock and wider stud spacing, causing his walls to shake while yours did not.
The EV 18 was likely putting out as much (or more) 15.66 Hz and 23.49 Hz than the Schumann resonance (which has changed over the years..). My 5/8" control room walls will "flap" with about 100 dB SPL at 15 Hz.
Regarding plasma tweeters- an ozone generator is a lot more cost effective and efficient way to produce ozone 😉 .

A 20hz wave is 56 feet. When we tune our boxes we use 1/4 wave or a harmonic of that. Same with a WiFi or cell antenna I think 2.4 ghz is 11 inches a 1/4 wave is somewhere like 2.8 inches I'm guessing but you get the idea.
If my neighbor'so house was exactly 56 feet away from my speaker and I was playing 20hz for a period of time it could Crack the whip when the waves hit.
