So many variables. It depends on the individual cabs. I have Berg CN cabs and the 112 and 210 are very similar in power handling and sensitivity so they work very well together. The 112 has more low end, the 210 will go just as low if you tweak your eq a bit. So my highly uneducated belief is that hose two factors, power handling and sensitivity are key to making unlike cabs work together, more so than frequency response. The Berg cabs seem designed to work well together, others maybe not.
