kcarlile,
Here's the page at audiovideoreviews.com where you can see the NRC measurements of the M80ti, including its impedance vs frequency curve, which is very smooth. Sorry I don't know how to do the link thing:
www.soundstagemagazine.com/measurements/axiom_m80ti/
If you want to check out other loudspeakers, go to audiovideoreviews.com, then select Home Loudspeakers, find the speaker in the list that has "NRC" after it, then click on the measurement logo at the top of the review and scroll down to the impedance measurements.
In contrast to the M80s relatively smooth curve, take a look at the impedance curve of the M2i, which varies all over the place. This illustrates how impedance has nothing to do with sound quality or a smooth and even frequency response. The M2i's frequency response is very smooth and linear, whereas the impedance curve is quite variable.
Regards,
