I agree and understand how important is moving the speakers to find the symmetrical impulse from both channels BUT in microscopic movement we mainly correct the vibration of speakers which indeed effects the whole things.
in my view the microscopic movements is bringing the luck to have both speakers vibrate in way to generate same impulses ...

It would be hard to see how at microscopic level vibration comes to the picture. It might of course offset pulse response but to a degree but the degree would be much lower than the offset by distance discrepancy. It is not to mention that feeling that vibration is on the picture would be identical to stating that vibration-prone speakers have no DPoLS dependency. I do not think that this is the case.

I do not want to jump from DPoLS to vibration subject but I feel that vibration of speaks is not a problem at all. It is the problem that it very obvious, easy to demonstrate and very easy to sell to people. Some companies build up on the fear of vibration and spend a lot of efforts to deal with it (Revel foe instance) but still end up with horrible result (that might have no connection to vibration at all). Some companies do include the presumption of vibration into the design (the Living Voice is the example, even though I do not know how they sound and some sources suggest that light and vibrating enclosures has nothing to do with sound but with LV intention to same on cross-ocean shipment.)

Still, whatever impact the vibrations have I think in phase vibrating of both speakers might be desirable. Here is what the pulses need to be read by laser with taking into consideration the distances between the listener and speakers – very interesting subject but absolutely not observed….

I still would feel that the box vibrations are no what we deal during DPoLS setting but no one can be certain about anything what we are taking about Quantum Mechanics of Loudspeakers Setup. The sad part is no one taking or dealing with this “Quantum Mechanics”. I am sure if some serious sound company would put their math and experimental recourses into the subjects then we would see a small $149.95 devise that would set find for us DPoLS very easy.
