Blah-Blah:
From what you say, speaker impedance value has no meaning because it varies so much.
Yet all the manufacturers provide impedance ratings for their speakers, and there is not much concern that this parameter cannot be precisely defined.
Rated impedance is a prevaling value across the frequency range. It means that 4 Ohm speaker, for example, will have about 4 Ohm impedance from 200 to 12,000 Hz. Although this speaker may have impedance of 6 Ohm at 20,000 Hz and 30 Ohm at main resonance, it has to be connected to the 4 Ohm tap.
Your statement that amp will control speaker better on the lower tap is incorrect. Tube amp will better control speaker on the nominal tap. 6 Ohm speaker should neither be used on 4 Ohm nor on 8 Ohm tap. Tube and SS amps are very different with regard to their optimal load.
