I've got a couple really nice retro Cerwin-Vega AT-12 3-ways but sadly, the cones on the subs are falling apart and just don't sound good anymore... I was just wondering if I could put a couple pioneer TS-W303R 12s in as a replacement for both? the rms rating on the pioneers is 250w and the rms on the cerwins are 400. Would this work? I desperately need some low-end...
