Why is only one axis labeled? I'm not going to take your word without seeing the original source, because you have switched from discussing to arguing.Here’s impedance plots using speakerboxlite and an Alpine Type R sub. The impedance is altered when the sub is placed in different enclosures.
Red = ported, Green = sealed, Orange = IB/free air, Blue is band pass.

Why does impedance change as the coil moves?Considering impedance changes as the coil moves...anything that effects coil movement (like a box) effects impedance...
I'm willing to be wrong if anyone can conclusively prove it. It's obvious to me that none of you have ever even questioned the concept before, so now you're desperately trying to justify your belief.
