Mackie 808S power mixer (600x2 watts) stereo with a matched pair of Mackie C300 12" 2-ways and an EV Sxb120 12" 300 watt sub. Works for me - just four easy pieces to transport and I can entertain 50 - 500 with no problem. Also, 2 Sound Technology 12" wedge monitors and a spare Crate 10." I also have a Peavey KBa50 with an XLR input I can use for smaller venues.
