A flat measured response is sometimes fools gold. The output of a loudspeaker in a static input of, say, 85db, or 90db, is one indicator. Yet, when the dynamic signal of real music is applied, there is no emperical proof that the 'dynamic' output will remain anywhere near that first measurement.
The only (fundamental) test is listening.
I have designed speakers which measure reasonably flat, insofar as the static input goes, with tragic results with dynamic input.
Now, you could argue that multiple input volumes starting at very soft, to very loud with sweeps; then overlay the results to compare. That could give some meaningful data, but its still not the 'real' test.
Speaker design is truly 'art and science' and transcends science, and goes into the artform arena. It takes a special person who can do both, then be objective with the results. That is why there are many loudspeakers that are 'technically' correct, yet leave us wanting musically.
So, "How important...."
Somewhat, however....
