So I finally got to use my twin live and love it all but the speakers are a little flat I think, they are great but I was going to get on of hogans cabs - But how would this work, The way it is on the back of the amp is there;s to jacks but one has wired going into rather than a jack and the other one is only 4 ohm output and I don't thing that's enough for 2x12". Any help?
Would I need a power amp for this?

You should have 2 outputs on the back of the amp. One labled "speaker", and one labled "ext. speaker". If you want to run a 2x12 cab instead of the internal speakers, you unplug the jack in the one labled speaker and plug in your cab. Either way, when running two 8 ohm 12's, it's a 4 ohm load that your amp sees, and that's exactly what you want. If you're going to cart a twin around anyway, you may just want to put your new speakers in the amp, in place of the old ones. If you were planning on using all 4 speakers, then it's a 2 ohm situation. Someone more knowledgable than me will have to tell you if this is safe to do, without frying your output transformer. Doing this would be overkill anyway, IMHO.

No I just play in running it straight to the cabinet, I also like the look of the cabinet, i'm gonna take the speakers out of the Twin cab to lessen weight. But what's the purpose of a power amp, I know it powers the speaker but I mean what's the point of jerry's mc if the twin already has one.
sorry but i have no clue about that don't laugh to hard :lol:

101, bro.

A Twin is what most people call a "combo" meaning in it, the box has:
- preamp to shape your tone (comes after your input jack)
- poweramp to boost your signal from line level (from preamp) to speaker level
- speakers to broadcast your tone

Jerry ran his "Twins": guitar > Twin input > modification output before the poweramp > external poweramp > cabs

That was so he could push, what, some 400W of power without the poweramp tubes coloring his sound.

If you like your Twin, I'd suggest trying different speakers in that box that have neodymium magnets that are very light. Weber has neomags that sound like JBLs and are so light! The preamp and the poweramp are what takes up a butt-ton of the weight. I'm sure TigerStrat will agree but the bulk of the weight is in the non-speaker section and I say this cuz we both have Dual showman reverbs (twin in a head. head = only pre & poweramp no speakers) and they are freakin' heavy!!

+1 on the DSR weight. I have one too and it's heavier than many of the combos I've owned.

If you want to run a separate cabinet -- there are advantages to that -- you can put your Twin chassis into a head cabinet, like I used to do ...

The problem with putting JBL E-120s into a Twin is it makes it unbelievably heavy. I have yet to hear anything that sounds "exactly" like the E120s. The E120 is not that pleasing heard on its own, actually, but man, it cuts through the mix well.

The separate cab is nice because you can carry a 1X12 for smaller venues and the 2X12 for bigger ones (or the 3X12 if you're playing Madison Square Garden). It's also much easier to swap speakers in the 2X12 cabinets with the clips if you want something that breaks up a little sometimes.

I have the above head cab and light-duty road case for sale for $350 if anyone wants it; it's a custom job with cocoa tolex and a wheat grille, pre-drilled for the head and reverb tank. Like-new shape.

One thing you learn pretty quickly when you are gigging regularly ... casters are your friend. The road case above has little wheels so you can tilt it up and roll it. The 2X12 I used had a pro AVS road case with great casters on it, I could stack everything on it and roll it into the venues.

Stairs, you're on your own ... LOL

most of the weight is the chassis and the iron and magnets.

Agreed. Point is a Twin w/o speakers is not that much lighter and not that much easier to lug around. It's still a big fucking heavy box that is not extremely top heavy.
