Hey guys and gals. I'm really in a pickle on which setup I want. Both will cost me the same. I'm in a rock band and my acme just doesn't cut through the mix. Weight is not an issue as my band has a road crew. We play from large outdoor events to bars. I'm planning on using my sansamp rbi preamp. Rig 1 - 2 avatar 2x12s and a qsc 2402. Rig 2 - 1 or 2 avatar 2x10's biamped with an acme b4 powered by a qsc plx 3402. The big difference between these rigs is that I could use a borrowed power amp for awhile on rig 1, but eventually I'll need to get my own power amp.
