This is a puzzlingly large cab for a 2x12, it's not the regular Blackface 2x12 it's quite a bit bigger, almost looks like a 2x15.  39" X 29" X 11.5".  But they weren't wrong, the extra space & heft gives it a warm, sweet, punch.  I've put a pair of re-coned Oxfords in here which came with a Blackface Bassman cab I got a while back. These are my favourite speakers for the piggyback bassman and I've been looking for the right cab to put them in for a whle.  And this is right cab.  I know it's pricey, but if you hear it you'll understand why, it's a really sweet cab that you just don't hear every day.  Used to be owned by Bill.
