Damn, I hate stories about blowing drivers. That really surprises me because I was driving them with amps capable of 1000 watts into 4 ohms, with no problemo in a large, well damped room.
When you say "crazy loud" were you sitting there in front of them and actually listening when the driver crapped out?? You shouldn't be turning them way up and listening from another part of the house. You should be able to get 85+dB averages and peaks of say 105 or so without blowing things up. Compressed rock can be played over 90dB averages, generally without harm. Usually a speaker will blow because of a short with power on or underpowered clipping blowing the tweeters. I'm surprised that a speaker of this quality blew at any kind of level that you'd actually listen to.
