For a single 12 cab, I'd look for an original Bogner Cube cab or take a look at the
Port City Waves cabs.
I also like the Suhr Badger single 12 since it is front loading, making speaker swaps
a breeze.

2X12's Port City or Reeves or Reinhardt or the very popular Bogner OS 2X12

In a 4X12, take a look at the vintage Marshall reproduction cabs from Southbay Ampworks or the Bogner 4X12's. The Reeves cabs are also exceptional.

For Bass, I'd go for a Reeves single 15 or a Berg 6X10 or both, but most of your bass
tracking will be DI, so you just may want a cab to add some live sound.
Reeves is also working on a new 4X10 and you may want to look at the Ashdown 4X10. For extra deep low B fullness, nothing tops an EV single 18 Road Ready cab.
If you come across a vintage '73 or earlier Ampeg SVT cab loaded with CTS AlNiCo's
GRAB IT! Great cab for bass and big block guitar amps.

I would always go for cabs built with dovetail joints as they are the strongest.

If you'd like something in a tone wood cab, check out Bob Burt Custom Cabinets
or the fine cabs from Curt Emery at Emery Sound.

Since space is limited, you may also want to consider options like a covertable back
to allows closed or open operation.
