Re: OK - seriously thinking powered speakers for the band
I'm with zz. Once you get past two speakers separate amps and speakers makes more sense.
EDIT...had to leave the house for a bit.
1) I don't find running two cords to each speaker makes things simple.
2) Good speakers tend to last longer than amplifiers.
3) Knobs on active speakers get moved/broken and sometimes you get into one knob/button menu/options LCD screen hell. A case(s) of power amps plus any other processing (X-over, comp, EQ) puts all those controls in one place, not all over the stage and in the case of monitors, on the floor. Plus, after the gig the rack cover goes back on so controls don't get to moving/broken. Next gig...open the rack and walla...everything is right where you left it...at least 99% of the time. Patch in, power up and go.
4) Separate amps/processors are easier to maintain. Pop the cover once a year...blow out the crud and clean all the contacts.
I will admit my way will probably cost you 25% more in the short run. I recommend Allen&Heath mixers, EV speakers, Crown power and dbx processing.
