Okay, buzz, but the rest of what you said implied that the impedance changes over time. The impedance does not change, though the load does.
Let's say you have a pair of identical speakers with a bass resonance at 60 Hz with a 50 ohm impedance, and a midrange impedance trough at 500 Hz with an impedance of 4 ohms. The impedance is matched on both channels.
But if you play a 100 Hz tone through one channel and a 500 Hz tone through the other, the impedance of each speaker will stay the same at 100 Hz and at 500 Hz for both the speakers, but the LOAD on the two channels of the amp will be different due to the different frequencies of the signals being sent.

A good answer is easier with a clear question giving the make and model of everything.
