Hello folks, quick question I hope: I'm putting together a modest PA for our 4 piece group.We have bass+guits-own amps miked at times or DI, light keys-Roland thru PA only, 4vox, sml/med venues. I want it compact and light in weight for lugging. I already have: Mixwiz wz3 16.2 mixer, DBX eq, QSC PLX 2402, 2 old Community 15”passive mons with tweeter horns for fills or sell?. 2 hotspots. My plan is to add:1or2 cheapo Beh F1320D pwrd mons, Mains on Passive EV TX1122, My dilemma is: 1 pwrd sub-EV ZXA1 12" (561b)or EV ELX118p, 18" (70lbs). I think the 12" in the 2way mains will help the clarity an definition and a good sub will fill it all out. So I'm torn between the 2 subs I mentioned and wondered if I could get by with the ZXA1 or end up having to get another later? Thoughts? Thanks!
