Even the guy who makes these particular measurements doesn't usually say anything much about them in his reviews. As Atkinson says, the resonant decays don't usually cause much problem in most speakers. "However, loudspeakers with such audible resonant problems appear to be very rare these days."

This measurement doesn't seem to work very well for electrostatic loudspeakers and other panel speakers, which seem to look pretty bad on it even though they actually sound pretty good..

In Stereophile, I look primarily at the impedance, sensitivity, frequency response and dispersion. Soundstage also measures distortion.

Speaker A seems to have a much more resonance in the midrange since the lines fall off considerably slower (lines are closer together). This may indicate there is some muddiness in the midrange--which doesn't look very flat anyway.

The peakiness between 16-17 kHz is high enough that it shouldn't be a problem.

Speaker B shows the midrange sound decays more rapidly, which is a plus. The chief thing is that it appears to have a much flatter frequency response, though, and that is better seen in other graphs.

My Stratus Minis beat both of them in this sort of measurement.
