Thanks mijostyn ,your explanation is very clear and very useful....
It make me realize why it is way simpler with my mechanical way....
Because i adressed the way the room response to the speakers, with a large bandwith instead of a narrow frequency, it is way more easier to correct the room responding to each specific volume of each speaker and correct this asymmetry of speaker by changing the room treatment but mainly the distribution of some pressure zone by modification of Helmotlz resonators, to reequilibrate and compensate for this difference in volume by each speaker....Each Helmoltz resonator is modified to enhance some frequencies and damping others...The location is important also....My speakers stay the same but the room adapt itself specifically for each one for my ears...
Like you tough, it takes me 10 to 12 weeks of experiments but it was never frustrating , only fun, because it was almost always some relative improvement each day and anyway easy to correct it when unsatisfied.... It is easy to correct the timbre of some instrument by feedback which is immediate in the instant of the listening experiment... The imaging i have is very good and i cannot attribute that to my average speakers even if they are good speakers ....i never have this imaging before acoustic control...especially the coupling of the imaging and of the soundstage...
You are right about the fact that imaging is related to volume but imaging is related in a no less important way to the precise timing thresholds linked to early and late reflections, and to the relation of the direct sound of the speakers and back reflection timing.... Not only volume....It is the timing and the way the resonators marked out the waving flow from each speakers for each separate ear that also play a major role.... Each resonator is a different possible pressure zone which is a buoy also for the brain hearing processing the 2 first wavefront for each ear... Anyway it is my experience and i am not acoustician but i read research papers about imaging that inspire my idea to use resonators....
Your explanation made me more fond and happy to have used my method which is very more efficient in my case than anything i could have done....
I am pretty sure that i would not have been able to do it by narrow frequency response and a comparative listening like you tried...
But like i said my method is not for most people with a system in a living room.... Our wife will divorce....mine sure....
Thanks for your very interesting post ....
My best to you....
