Is the speaker impedance constant or variable?


We read lots of tech specs on the speakers and know that sometimes speaker impedance may vary from 2 to 6 ohms or some other values.
Does that mean that this impedance vary within one speaker or different speakers of the same brand/model might have differences?
Does the speaker impedance vary on different freequencies or it has pure active and constant resistance? Another words what are the components of the speaker impedance? Equivalent circuit diagram link or e-mail will be helpful.

It differs with the frequency that is being produced, and its usually toward the lowend on the scale that you see a sharp drop in the ohmage from norm. There are others out there that can explain it better than I, but I do know there is very little constant about ohmage, and usually if you look into the fine print of a speaker you will see that the ohmage is given as an average, which means it is not constant.
