Hmmm, well i do have access to orange cabs and they are definately cheaper than the Mesa Recitifer 4x12!
Would a mesa amp go well with an orange cab? Hmm either the 4x12HP or the 1x12 if money is an issue...
So yeah sounds like the most popular choice is the orange then?
Bear in mind that virtually any 4x12 is pretty much impossible to load in and out of a car on your own. The Orange 2x12 is a particularly large and heavy 2x12, and is virtually a heavy as some 4x12's.
From the list you gave at the beginning, Personally, I would be most interested in the Genz benz 2x12. It will be very well constructed. However, the speakers (Emi Private Jacks) are greenback copies, and not ideal for metal.
For someone who doesn't have roadies, I always recommend 2x12s. They have reasonable portability, yet are still gutsy enough to gig comfortably with. For metal and heavy rock you need a closed back cab (or a ported cab). Open backs do not have the "thunk" required.
The TSLC212 cab you mentioned is really not bad at all. It has good speakers, and is several tiumes better than a Marshall 1936 or 1922 2x12 cab.
BTW, what is your budget for a cab ? If you have plenty of cash, I'd be looking at a Bogner oversized 2x12, or a Dr.Z 2x12, or a THD 2x12. The THD in particular is a great combination of size, presence and portability - thoroughly recommended. The Marshall 2061CX is another very, very nice 2x12, which is easily available.
