    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..

    I actually bought another G12-65 (reissue) and, weirdly, it sounds better than the remaining vintage one! Smoother, slightly thicker in the mids. So that's why I was thinking of swapping out the vintage unit for a G12-80 which I know sounds great in my 4x12

    G12-80 should be 100db. At least that's what it's rated in my Randall RG-80 from 1981.

    I have a quad of Rola G12-80's in a 1982a cab, and Idk about the db rating but it is much much louder than other Marshall 4x12's I have with 75's or v30's..the thing sounds frickin great but it'll take your head off ifn you aint careful..

    Thanks! And G12-65 is, I think, 97. Too much of a mismatch?

    My G12-80 4x12 is the best sounding cab I've owned. Don't know if it's any louder than other cabs I've owned but with my 2203 it so woody and warm and balanced. The last 4x12 I had was loaded with the Marshall Vintage Modern Greenback G12Cs and I didn't like it at all. Fizzy under Distortion, boxy-sounding and lacking any real weight.

    G12-80 will be 15-20% louder, I believe.

    I have a G12-80 loaded B-cab from 1978, I only A/B’d it with a Mesa Stiletto cab (vintage 30’s, angled) and they seemed equally loud. They will both take your head off, but the Marshall cab does it in a warm, gut wrenching way. Especially with my ‘71 Super Tremolo. I sold the Mesa cab

    I’ve got a pair in an oversize Mesa style 2 x12 cab I built . Great sounding speakers they’re killer for metal , super clear and punchy without any horrible ear fatiguing high end like some speakers .
