High power handling speakers

I have been reading interesting things over at Avsforum about a speaker called the JTR Triple 12LF. They were designed for the pro market but are now adapted for the home.

Thanks to all for your input. The idea of having several drives is perfect to handle all the power, problem is that the AV123 is way to big for my family room (not a dedicated Home Theater .... yet). I will start my research and aviability in the used market for all the speakers that you recomends me.
If someone have more options, please let me know.

I forgot to mention that, because they will be in my family room, speakers need to be nice in their design, but not necessary "WAF" compliant: I can handle a fight, but not a divorce, if second option happens, Im sure that she and her lawyer will take my audio system out of me!!!!!!

so you want high SPL's not necesarrily high power handling, correct?

In that Case the JBL's mentioned above are great, so are Klipschhorns, Klipsch Belles, and I would also highly recommend Definitive Technology Super Towers BP7000 SC's. Great speakers all.

A friend has his home theater in his two car garage. Using an HK receiver he powers Klipsch Cornwalls 20 feet away which cost him $600. A pair of subs behind his listening position provide the growl, and two sets of inexpensive surround speakers provide the ambiance. His setup actually sounds a real theater . In short - quality horns in a large room. Not high end audio, but high end PA system is the sound of a real theater!
