Nice copout.

I really *was* curious, since the graphs for Madisound seem to be in a
different format than the others.

I went to the manufacturer's sites for both - graphs there make sense.
The curves for those ribons are going to be a PITA to deal with
considering the horrible impedance vs frequency response.

Can you quantify what you mean by "horrible"? How do you come to this
conclusion?

I'd take a high-end silk dome tweeter anyday. Gheez - the first one that
Madisound lists is a whoppping 10db down at 20Khz frmo the midrange.

How does this differ from the, say, VIFA XT25TG30-04, a megabucks ring
tweeter?

They don't seem to label the different curves but there are several of
the curves that dip that much. The few tweeter graphs that I looked
at from ScanSpeak and VIFA all seemed to have the same sort of
downward tilt in the same sort of range of roughly 10dB, depending on
which curve you look at. It seems to me that due to the diffeent
testing methods and different graphing techniques used, it's like
comparing apples with oranges.
