I've tried...really tried to capture the mojo that I get with the SuperD and the pine 2x12 with a smaller cab. Less volume for smaller venues is a must and I just can't find that magic. The most elusive part is that I'm pretty convinced that you can't simply take the same speaker and cram it into a smaller cab. There's a resonance and timber that the 2x12 has in spades that just doesn't translate with 1x12s I've tried so far. Before I explain what I've done, what do you guys do? Same speakers in a similarly constructed cab in a smaller format? Or do you take a crap shoot and just audition a bazillion cabs?
A couple of guidelines...closed back is a must for volume control on cramped stages, needs to be wide enough for the head to sit on.
