To put this another way, if you feed MUSIC to a high-power amplifier,
then it will either drive the speakers cleanly or, if the signal level gets
too high, blow the speaker fuse.  It won't fry the tweeter unless there
is a very high level of high-frequency energy in the music, which there
almost never is.

The argument about using a lower-powered amplifier to protect your tweeter
applies only if you have a separate amplifier for the tweeter which is
fed only high-frequency signals.  There, there is no danger of clipping
of high-amplitude low-frequency signals (which aren't supposed to be
reaching the tweeter at all) generating harmonics.  Note that tweeters
are likely to be rated for 5 or 10 watts power input, so protecting them
by using a power amplifier which is completely incapable of damaging them
means having an amplifier which can't reasonably drive the woofer at all.
