I guess that may be me you are referring to, as I'm a fan of the BA10-2 combined with the BA12-3. I haven't used a pair of the 10s, so I can't compare, but I find that the 10 and 12 cabinets complement each other well. The 10 provides solid punch and the 12 gives nice depth, so you get both boom and bloom. I have always liked three-way cabinets for their balanced sound, and that's the quality I get from this combination. However, having separate cabinets saves the back and makes it easier to load in and out. I have received nothing but compliments about my sound, from fellow musicians and audience members alike, when using the combined cabinets in live situations. Also, having two different cabinets provides alternatives when the gig only calls for a single cabinet.
