@DKL there isn’t really an easy way to answer this. There is what we call a power dissipation, in the sense that the higher frequencies don’t see the same amount of power as the woofer. I talk a little about it in this video:
The easiest way to guesstimate power handling, is to go off of what the woofer can handle. Model that in winISD and see how much power you can use before mechanical limits. That will give you a decent representation of power handling.
