Can speaker harmonic distortion decrease to 1% or less if SPL is lowered enough?

I did not miss it, but my day job was high-speed (RF/mW) analog IC design, not audio, and certainly not speaker design. I never claimed to be an expert in everything and have stated speaker design is not my area of expertise. As far as I know I did not state falsehoods but responded to other posts. In any event I am out as this has gone far enough for me and devolving into personal attacks.

Sorry, language barrier: I never meant that these, say outdated ideas were your own, really. I know them from the past, naturally from somebody else. I followed them, partly, to no avail. Remorse on my side.
