The biggest power handling limitation is usually the thermal capacity of the midbass and tweeter voice coils. They cannot make them handle more power without degrading the sound quality.
Someone here launched a JL crossover and the fact that the crossover is totally sealed makes it too difficult to determine what went bad. There was no output from the HP and the tweeter was still operational.
