Acoustical feedback energy system

This could be an inductive spike. it could be quite significant.

Not sure about "spike". Fuzes usually do not react on spikes, they need time to fire-up. It was some serious build-up of voltage, and backsurge, as I was connected to a municipal powergrid.

Analog multi-meter + digital multi-meter,limit physical ?
Dirac surge, inrush Voltage,inrush Amperage,inrush Pulsation !?

Dirac Sea,Moray Sea,TV-'snow' to Tele-Audio-Vision,TAV 'snow',RANDOM process ( Farnsworth !?)

Device in cool-able ambient,up ultra ?

Well, I'm not an expert in such keywords, and in electric engineering in general; I understand how electricity works, but designing a complex system is out of my interest. All I can say is that speakers were not damaged. So, whatever surge there was, it did not damage a rather basic signal-amplifying circuitry of cheap analog loudspeakers. What is important is that all loudspeakers amplify the same sinewave signal source, without any phase delay. The frequency I believe depends on distances, room modes, and ambient temperature which was I guess 25C. The cheap small high-frequency speaker cones are usually directional, so distance from the flooring is not so much an important factor - in my experiment the speaker cones were about 15cm off the floor.

When I visited between 2005-2010 in average 3x per week the Campo&Cardoso electric repair office in O'Porto/PT,ancient a transformer production entity,there I met an engineer,whose branch was/is? loudspeaker - high end- construction !
He told me about mono-/stereo hear differences from us male humens !
Your description reminds me the reclam in the End-80' about the new sound system : dolby surround ,and as video-audio example about virtual-synthetical aesthetiks a concert hall stage,with curtains down and behind - instead an orchestra- a DCD ( later DVD) play recorder,the sound to the audience,included ECHO Hall,like ' in real' ,and no " play back",as so often !

You are right, this does look like home-theater surround-sound system. But there are, of course, uncomparable differences, and unexpected operation modes. There's a vast world to explore in opposite-speaker designs. Overunity FTW.
