the EA setup seems like the best compromise. the nl210 footprint is amazingly small, and i've fed a whole 3,000 hall w/ just my iAMP800 + nl210. terrific little combo. but dont discount the epifani ul112's. i've been using a pair w/ the ul502 head for a few months now, and day in night out, they've been SOOOO good to me. fat, focused kick that's louder than you'll ever need. i thought i'd miss the rounded punch of 10" speakers, but the ul112's have me quickly rethinking that. and they're stupendously light to carry. like empty briefcases.
