When a relatively simple and basic point is made briefly, there's some danger of it being inundated with a flood of terminology in response. Of course there was no suggestion that a speaker is a fixed resistor, and the varying impedance(due to capacitive and inductive reactance)with frequency was mentioned. Ohm's Law(sometimes phrased in the I=E/Z form to use Z to emphasize impedance rather than pure resistance)specifies the current in effect in a given speaker at a given frequency and voltage input. This is a fixed amount of current, dependent on the speaker, which can be neither lower nor higher, regardless of the amplifier.
This was pointed out simply because of an incorrect implication in a previous reply that the capabilities of an amplifier could change the current specified by Ohm's Law and that somehow the speaker would then work better.
