Curious but I have used FRFR for ages. I use QSC K12 as my amp speaker. I also use a variety of impulses from all brands, but my query is, which in your opinion is the best IR for a QSC through Helix? I see 1x12, 2x12, 4x12 and still wonder which you think sounds best. Reason is, I can’t tell much difference. I’m talking classic rock or 80’s metal, funk and clean. I’ve never found a thread on which IR is best suited. As I said, my FRFR is my amp speaker, not just monitor. Thanks for any help
