How long untill I can really Flog them Hard

I agree with Chayro to some extent, but also have to ask how loud is loud? You can get a Db meter at Radio Shack on the cheap side which will give you a way to measure the strength of the signal at your listening position. At 100Db your getting a pretty loud sound pressure. I bought one out of curiosity you may want to as well.
I don't think there are many speakers made for Audiophiles that are capable of prolonged high spl levels, that is why I agree with Charyo . I have a pair of Klipsch LaScalas (amongst others) that can do that but they are also marketed to clubs and other "pro" venues. If it is much lower you may not really need those speakers, the sound quality is different and may not be to your liking.

More speakers are "blown" from too little power than too much. If your amp is clipping, it sends off all kinds of nasties to the speaker, especially the tweeter, which cant take much to start with. What amp are you using? The 802 should take plenty of power.

He damaged the speakers by plugging/unplugging an RCA input with the volume up.

Lets cut the guy a break (although he blamed his wife for the incident). Flog away.

I have the same question because I've got a new pair of paradigm studio 20's. I'm taking it kind of easy for 100 hours or so since I cranked my then new studio 10's on day 1 or 2, heard a pop then backed off immediately. After that, the speaker that popped would make that same popping / distorting sound that I initially heard, from both the midbass and tweeter, when turned up loud. By comparison, the speaker that didn't pop could be turned up 4 or 5 d.b.'s louder (according to the volume indicator on my pre-amp) and that extra 4 or 5 d.b.'s would have made a world of difference to me.
