Re: Looking for 2x12 small cabinet
It won't fit your height criteria, but if you you can find an older Mesa 212 Half-Back they are wonderful--best 212 ever made, IMO. They are a vertical 212 with a metal grill; and not that much smaller than the Mesa 412 Half-Back--which is a very small 412. Top of the cab is open-back, and usually fitted with a Celestion/Mesa Black Shadow C90. You'll sometimes see them with a C90 (rarely), or the Eminence/BlackShadow MS-12 (a JBL Clone), or the highly-regarded EVM in the bottom (BEST!). The bottom of the cab is closed back AND, it is Theile-ported for maximum low-end response. They just work really great on a small stage. The open top gives you the "air" and spaciousness of an open-back--like a combo; while bottom part of the cab provides the low-end grunt and projection of a 412. I have one with the C90/MS-12 combination. It will fit in the trunk of my girlfriend's 1999 Accord Coupe. The stage footprint is about the same as a Fender Twin Reverb combo--just a little narrower and a little deeper. They came with pop-out wheels, and I usually pop them out at the gig to connect the cab to the floor for better bass response. And the other thing I like about it is that it puts the amp head at a readable level, so I'm not bending over and trying to read the knobs in the dark...a win-win for my old eyes and my aching back!
Mesa does make a new version of this cab--the Vertical Recto 212; with a totally closed-back and Celestion V30s (same speakers as the Horizontal Recto 212).
If you like Mesa, and the idea of an open and closed back cab in one--they do offer the Road King cabs. The Road King amp has the ability to set each channel to use different power levels, different tube types and SS or tube rectification--and assign each channel to one of two different speakers. Very handy if you want both open back and closed back sounds.
The Mesa cabs are very well-built, and use top-grade plywood. If you are doing any kind of gigging, or even merely transporting you cab, I would STRONGLY recommend that you avoid particleboard and MDF construction.
Good luck!
