I have to plug my EV's here- not because I'm selling them, but because i think they are the clearest and lightest around. I always used an outboard mixer/power amp or powered mixer whether as a solo or with the band. I can't go with the idea of set it and forget it powered speakers. If you realize you need to make an adjustment to volume or tone, you can't very well run back and forth from your keyboard to the speakers until you get it right, even though you thought it was right before you started. The EVsb122 sub is smooth as silk, and the zx1's do with 8" what others need 10 or 12 to do. The weight (36lb sub/16 lb satellite, and pole) of the tower is less than that of a bose L1 tower. And the can be carried separately to lighten the load. I use a bag with both zx1's in it and covers for the subs.It requires pole mounting and a jumper cable between both speakers rather than a click of the stick tower stuff, but that is minimal time for maximum profit and quality..the Mackies are very expensive as are the Yamahas. If powered speaker is the way to go, I would do as suggested and look at the new EV zlx line, or current live x/zx lines.
