How you digging those 2x12 OS Bog cabs?? Although I know there's a "secret weapon" currently in development as per new 2x12's, I am still keen on the sonic qualities of the over-size, closed back 2x12 for my Uberschall. I've had a good chat with TM, and also my Canadian distributor, and for purposes of the studio, my guess is a 2x12 loaded with G12K100's is the best bet.
The thing that appeals to me about the oversize design (closed back) is the internal resonance and bass response). Smaller cabs, in my playing experience, lend themselves to tighter bass response, and punch. But I love ambient miking, and the sound of an OS has always been fuller, bigger, and more colorful.
Anyway, off for a mini-vacation surfing...catch y'all on the flipside!!
