Speaker ports and impedance


Wise ones,
Is there a relationship between a speaker's electrical impedance plot and the cabinet design. I have noticed that J.A of Stereophile often correlates an impedance change at the tuned frequency of a speaker's port. I'm guessing it has something to do with physical impedance, but I have not found a reference in Harley's book.

Thanks for all the responses.

Thinkat and Bombaywalla, you guys confirm what I observed, so now the question is: why does it do that?

Piezo, If what you say is true, then what could account for the correlation between impedance and port tuning?

Gs5556, is this to say there is a relationship between physical impedance and electrical impedance?

Sean, I'm still reading - thanks,
