Big thanks Earl and VOTT!

I'll take your(pl) recommendation and just get the 802-8Gs from GPA. I can tri-amp tweeters, but like you said, why mess with the 811s in their sweet spot. Besides, if I can get enough high end out of the 802s and bi-amp, then I have an extra channel left over on the active XO for a sub...if I choose.

I'm not sure whether or not I'll sell the 806s yet. I'd like to keep them in case I ever sell the HKs, but I hate unused stuff laying around. I have no room for extraneous gear. I can't imagine I'd ever sell the HKs though. I know, famous last words.
