Nope.

"Your method is pure anarchy."

Nope.

"It is the electrical and thermal equivalent of tossing noise and hoping something comes out."

Nope, it is much more than that. One would have to understand things to see it though.

" And then, when something comes out, guessing and tweaking."

Nope. You just have to understand things enough.

"Using two controlled signals allows specific conditions to be duplicated, allowing for the capture of transient events."

Trivially true, it would not capture the effects of back-EMF as stated by Jacques. Transient events could be captured, but the kind of fleeting moment where the VI phase relationships mimick those of a particular frequency with actual speaker induced back-EMF would literally be so fleeting, that they would not represent the actuality of what real back-EMF would do.

"Any condition whatsoever can be duplicated, any thermal history, any location on the VI space, and any vector stimulus on the VI space."

Only if you were to provide an infinitely variable pair of frequencies, and then test for all of the possible combinations, including a set of conditions exactly similar to what occurs with back-EMF. This would obviously be impossible, as one could never cover all the possible frequency combinations, and unless you actually measured the back-EMF, you could never dial in the exact frequency and phase for the second injected frequency, if it were off just a bit, no longer equivalent to back-EMF.

On the other hand, the loudspeaker system does it automatically, continuously, and over a fairly wide range of frequencies. This means that you can run in any decent set of Phi Spectral multitones, and get back-EMF for all the relevant frequencies, pretty much guaranteed.

"...can be trivially induced into any amplifier via input drive signals and external drive forcing."

But only by using an infinitely variable set of test signals, and checking ALL possible combinations, Jacques was talking about one set of specific frequencies as being capable of doing this. No way.

It would help tremendously if you actually knew what you are talking about in this instance. But you don't.

What Jacques said is just not going to work, what you said could be made to work only with infinite test/measurement capabilities, perhaps we should set you to measuring them now, so we can all get some peace and quiet for a LONG time........
