    I have a 212 closed back cab that currently has 2 vintage 30s in it. I am going to swap one out with a g12m to see if I like the tone. Will it be ok to do this with a 100w marshall dsl head? The cab would then be a 85w cab. I rarely get the volume knob up over 3 on this amp. I read somewhere that each speaker should at least be 50w to run with a 100w head in any situation, is that true?

    on a different note, has any one tried this v30/g12m combo? Howd it sound?

    Yes. From my experience, my other guitar player has blown 2 G12Ms being used with a V30 in a 2x12. He is using a Solvtek Mig 50 head. Sounds great, but after blowing 2 I have gone to the double your speaker wattage rule.

    Well, when you use two speaker in series or parallel and they have the same impedance, the max amount of power the can hold is twice the lower wattage one. So in this case you got 2x25W=50W. If you push your amp to a higher level, for example 80W, then every speaker will have to manage 40W and this amount of power will damage the greenback (even though the V30 won't suffer since it can hold 60W).
    Sorry for my bad English

    Crap. Ok guys what would be a good alternative to mix in with my v30 then. I was originally going to try a g12H but that still is only 30w so I would be in the same boat. I was really hoping on getting that creamy greanback tone into the mix.

    Go for a G12-65 Heritage... it's expensive but it's a wonderful speaker... it's designed after the greenback but can handle 65W and maybe it's a little creamier than the greenback on the top-end.

    I had a cab with some Emi GB128s and they had a very GB sound and are rated at 120watts. I thought they sounded damn good.

    +1 I think it works better with a G12H-30 but its still a good choice. Bob

    I like the early break up / distortion you get from a g12h or g12m. The g12-65 prob doesnt do that being 60w, does it?
