Great cab. I came here to suggest the Bergantino HG410. It's taller/narrower than the standard 4x10 -- easier to fit onto cramped stages. One woofer does face rearward, which seems odd, but it definitely adds to the sound (but less so if there's no rear wall). It's also a sealed cabinet, with "tighter" lows than a ported cab, but I play five string tuned a half-step flat and the cab gets plenty deep.
I happen to use a pair of Bergantino HG310 cabs. As others have said, modularity can be a great benefit. I always carry both in my wagon, but for many gigs I can use just one. A single HG310, also with rear-facing woofer, is the size of a 2x10, but performs better IMO (except maybe if there's no rear wall).
The HG310 is 6 ohms, the HG410 is the standard 4 ohms.
