Because you don’t have it. You may think you do, but you do not. No matter what you do with acoustics, you cannot do what is required to accomplish this. Time to learn more about this before typing. You will save a lot of typing.I know that you are more knowledgeable than me and most in audio by a more than a small margin...
I hope that in spite of our different perspectives you smell the difference between me and some others....
BUT instead of explaining why i am supposed to be deluded you dismiss my experience...It is not enough....Sorry....We do not discuss "directed wiring" here... But the relation of acoustic with improvement of perception and the use of mechanical distributed Helmholtz resonators versus electronical means...I dont pretend that my solution is perfect it is not... But efficient at no cost it is....
I just listened the same files someone here proposed like a test and i lived the same perceptive experience or something near it because i am not frustrated about what he described and what i experience...
my remarks are only linked to a question: what acoustic control can do on par or better than Carver c9 ? it is a question but i had the impression that i lack nothing about all acoustical factors which other described.... I even prefer my grid to the synergetic research processor i listened to on many video on youtube....Anyway my ratio S.Q. /price is very high compared to them .... 😁
Explain to me why not? instead of dismissing without justification....
By the way my grid of Helmholtz resonators are not distributed randomly and i used the tweeter wavefront of one speaker and the bass driver of the other speaker to help my ears recreate the sense of space.... And contrary to a crosstalk control device i can work with "timbre perception" .... In my acoustic experience all factors like imaging, soundstage, LEV, are all linked in a kind of acoustical trade-off which i control with fine tuning mechanically the volume/neck ratio, the length.... It is not perfect but spectacular and sound natural to me....
