Square 412s are awesome for stoner metal, if you can find ones that are actually built for bass.
I use the Marshall VBC 412 which is basically the same model of Lemmy cab mentioned earlier but rear loaded instead of front loaded, and much easier to find (though still surprisingly hard).
I have used this cab (albeit briefly) with an SVT-CL with all knobs dimed and it did not fart out.
All of which is to say if you do find a cheap used square arranged 412 in your search, don't let the geometry discourage you, as long as it was designed with bass in mind it'll serve you fine.
