I'm looking to buy a couple of more speakers for use in Prom's and other set ups. I have 2 set ups as it is but I wouldn't mind selling my JBL EON's and replacing each mobile set up with 2 K-12's each. But for prom's would 4 K-12's be better than 2 EV ZXA5's for about 500 people? Is double the price for the EV's really double the performance of 2 K-12's? I've looked up the spec sheet's on both and it's really hard to put $1700 into each EV when you can get 2 K-12's for that amount. Either way I would be adding 4 Yorkville's for the sub's and the prom's no matter if I get the QSC's or EV's.
