Reply to RCF Art 312A mkIII vs QSC k12

Ive been borrowing my buddy's QSC k12s forever now, and I love them, but i need to stop being a bum and just buy my own. Ive read a lot about the 312a MkIIIs being better for less, but i have only ever heard the mk Is and mkIIs

was hoping to get some input, ive got 1200 i was budgeting for new tripod speakers

I already have a RCF L18P200-N 18in Woofer that works perfect so i don't even need to consider the Kbass units

whatcha believe?

edit - i need to be able to fill a space about the size of a hotel ballroom sometimes with sound and I like being able to do so with just 2 speakers, w/o pushing them into the red and blowing
