Last weekend for a 100 seat pub gig, we used the lead singer's PA, which was JBL active Eon's on posts mounted to Yorkville powered subs.
We also used a pair of those for keyboard and drum monitors and a two smaller 10" version of for floor monitors for myself and the other guitarist / lead singer. A Mackie 16 channel passive mixer through a rack with a couple compressors and 6 EQ's, two for FOH and one for each monitor mix. Perhaps a bit of overkill but it was all racked and pre-wired so easier to use it as-is than change it. Sounded really good - and it would have been way to easy to be way to loud. But that system will work in bars 4X that big - good to know.
My system is a Mackie Onyx through a Behringer Speaker processors (for x-over, EQ and compression) into 3 QSC power amps and then my Meyer UPA-1A's and a passive 18" Yorkville sub. I prefer not to take it out because 1) the Meyer's have fly-rig attachment points and aren't really meant to be pole mounted (no holes) and 2) those Meyer passive 112 boxes weight significantly more than those JBL active boxes. Maybe it we were to play outside, I could justify using the Meyer system with the 2000+ watts, but other than that, it's not worth the hassle.
And the last time I played an outdoor gig, we just rented 4 Yorkville Paralines with a pair of matching subs and used my Mackie Onyx. That system killed it in a park with about 500 people as far as 200 feet away. Wonderful, well dispersed sound and more than enough SPL for what we were doing.
