Excerpt: i have 4 QSC K12's and 4 Mackie SRM450v2's. I lined one Mackie v2 with one QSC K12, and from start to finish, Mackie wins. No speaker on the market can possibly compare to the Mackie SRM450v2, none. Plus, QSC's are way overpriced. I bought 2 Mackie SRM450v2's for $1,500. I bought 2 QSC K12's for $1,800. Plain and simple.....NOTHING beats Mackie in clearness, deep bass, loudness, no distortion, and just the best overall speaker.
