I used a G12-65 loaded 2x12 for years, until I blew one of the speakers. I'm thinking of replacing it with a G12-80 (I have a quad in my 4x12 that I love). Anyone know the dB / efficiency rating for a G12-80? Don't know if it would dominate the G12-65 in a mixed pair. I'd rather not desolder my G12-80s from my 4x12 to try it, just yet..
