    I am using a vintage 30 and a G12H-30 in a 2x12 cab. I know the vintage 30 should be louder, but am wondering if there will be any amp issues using them. Both are 16ohm wired separately to make 8ohm load, two jacks each one to a speaker, two speaker cords. When playing them i dont notice the vintage being noticebly louder. Playing out of a 40c on full power.

    both speakers should match in volume, for the most part. If they are both 100db efficiency, they will play the same volume, watt for watt. The only thing to keep in mind is that, when you mix speaker power, that you must rate the speakers by the lowest watt speaker.

    So, if you have, 2- 30 watt speakers, you multiply the watts by the amount of speakers. 2x30=60 watts total. If you have a 30 & a 60 watt speaker, you must rate the speakers both at 30 watts, then multiply, so having a 30=60, would be 30x2=60 total, even though the 1 speaker is 60 watts.

    The whole point is that, if you don't follow this guide, you run chance of blowing the lower powered speaker, then you'll have a mismatched cabinet ohm-wise.

    Thats what i thought. So playing 2-30 watt speakers with 40 watts should be ok. I kinda like the tone the two give.

    V30=60 watts
    H30=30 watts

    but, yes, you lower the rating of the 60 watt to 30, so your cab will be:

    30x2=60 watts

    40 watts will be easy enough to handle...

    As Dogs mentioned the 2x12 is good for 60 watts, so the DSL40C works with that.

    60 watts rating has nothing to do with volume/loudness. That is a power handling rating. It can handle up to 60 watts or 30 watts or whatever a speaker's specifications indicate.
    The speaker specification that give indication to efficiency and loudness is the SPL rating. Both of your speaker types average 100dB.

    I like a Vintage and G12H(55) mix.

    It seems like the v30 is a bit more "meaner sounding" than the G12, i kinda like the two together.The g12 is more mellow sounding to me.

    I actually have the helatone30 and 60. I am not sure. He lists them as just G12H-30's. They have the same magnet as the v30 or helatone60.

    Oh, I believe that is supposed to be a G12H Anniversary. It is described as being a bit milder on the upper ranges.
    The Vintage 30 is more aggressive there.
