Worth noting that Markbass makes at least two different 210s and at least two different 112s. I own, more or less, the smaller 112, in the form of the little CMD 121P combo. It's a potent little package and stacks well with another small 112.
Very little experience with the small 210, though I've played it once or twice in a GC. Should get a little louder than the small 112, but I preferred the 112.
The big 210 is, well, bigger sounding, and has a nicer tweeter. Louder than a 112 for sure. Tone... subjective, a little more tight/modern, maybe, a little less mid-growl. If I were getting one MB cab to do everything, this would be it.
Big 112... you know, there's another Markbass thread on here now you should check. Stouter and better tweeter than the little 112.
Among widely available commercial offerings, I think the MB stuff is pretty good. However, for the same price, roughly, as the little 112, you could have Duke at Audiokinesis build you a Hathor 1203. Roughly the same size, a few pounds lighter, and I would anticipate, loads better performance. I don't own one, but have considered replacing my combo with one. I would give the Audiokinesis thread a look. For Markbass, though, you've got my thoughts.
