Guys, I was using the QSC K12 with KW181 sub for the majority of the year and recently sold them. I am looking to get back into that system (or maybe get 2 KSubs instead) but before I do. I wanted to see your thoughts on similar systems from other manufacturers like Yamaha, EV or JBL (things that you can buy locally like at Guitar Center). Yes, I know there are brands that smoke these, but they aren't sold or serviced around here, plus they are more than I want to spend for a mobile DJ rig. The keys are that I can handle it myself, can roll it all in on one Rock N Roller, the bass pumps, and it sounds great! Hit me with your input!
