    I'm modifying my Origin 20c by putting a 12" speaker in place of the stock 10" v-type junior. The V-type Junior is rated at 50watts but only weighs 3.5lbs. A 12" Greenback is 7.9lbs but is rated at only 25watts. Will a Greenback be able to handle the volume of the Origin 20c ?

    Is the 20C ..20 watts? Sure. The 50 watt was just extra the way I see it.

    If you crank that Origin or hit it with a boost or a fuzz pedal, I'd bet your G12M 25w won't last very long.

    Should be ok if you don't crank it. The amp may easily crank more than 20W.

    All amps are rated for clean power. In heavy overdrive they can deliver about twice that power rating, if not more.

    A healthy "100 watt" Marshall Plexi spec super lead can put out 220 watts of electrical energy to the speakers when absolutely dimed out.

    A "20 watt" amp can put out over 40 in distortion.

    The G12H Anniversary is 30watts I'll probably go for that just for the extra 5 watts. Obviously there are 12's that are rated for more power but I don't like any of them.

    Did you try a Marshall type Vintage G12V type? They are the best among ceramic unless you would consider spending the $$$ for real AlNiCo.

    This amp is a dual EL34 power tube amp with three 12AX7's, plus a boost mode. I find it very hard to believe that it's so crippled through the circuit that it is only 20w max. Does anyone in Los Angeles have one of these? I'd be curious to test one out against some 30w amps and see how much it compares.

    The Marshall site is not giving up any wattage measurements with the boost engaged, from what I can see.

    Just use the lower wattage mode?

    I be skeptical with dual el34s.

    Yes didn't like it. Alnico Cream is a definite possibility. The Neo 250 is nice because it's light and sounds good.

    A vintage G12-65 would be a great fit and is the best 1x12 combo speaker, imo.

    there was a thread here somewhere, where it was disclosed, during testing (pre-production) the studio series were pumping out, like 22 watts +/-. I'd be willing to bet that the same method of power was used...

    The SL5 uses a single EL34 & puts out 5 watts...

    Once again I'm with @pedecamp,...Creamback 65. I'm not a fan of a Greenback as a single speaker, yeah they sound great in a 2-12 or a 4-12, but NOT as a stand alone speaker imo.
