If you look at a driver as a circuit, then there is a limit to the current it can take. So, that is a limitation, power rating of the cable or ribbon,
If you look at the motion limitations of a driver, you will find yet another set of ratings. They may not be stated but they exist and in the case of woofers one of these, cone excursion, has to be stated.
So, yes, too much clean power can still kill a driver, based on power rating of the circuit alone. You may also find that a driver pushed beyond its mechanical limits can be ruined at well under its total power rating.
Now bring a clipping amplifier to the party. Say its max RMS is 100 watts and, because your driver can take 300 watts, you crank that amp up to heaven. Guess what...it will exceed its maximum rating very happily and merrily distort for long enough to push the driver to madness. In doing so, it may start issuing such a horrific signal shape & impulse as to exceed the driver's mechanical limits. As the power is also getting closer to the electrical rating of the driver, things get even more stressful. If the amp does not give up, the driver will.
Tweeters just happen to be more limited but all driver have their limits.
