So 12's should cross lower than 8's, 15's lower than 12's, 18's lower than 15's, and God forbid anybody wants to use an EV 30W.

It's no accident tweeters are smaller than woofers.

You might get away with 800, 500 would be better.
Makes sense, that's why I was recommending a 500 hz crossover (or even a 300 hz crossover point if using a large format h.f. driver). I figured that above 500 hz you'd get much better sound out of a good h.f. compression driver/horn combo--the beaming explanation gives me a better understanding as to why. Do you think a 288 would do a better job with these (for a two way system) than an 802-8G crossed at 500 hz (for home hi-fi)?
