Hi James
Good question, I think the only difference is the finish and maybe cabinet construction? As far as i can tell both versions use the same drivers and probably the same crossovers. It was mentioned by an insider that the pro studios out there listen to them at lowish volume, but that its the consumers who push them to the limits.
I have the OB1's at the moment, and i can testify that they go very loud for there size and remain in control (in my small space) and that the cabinets do not rattle, so not sure how they could be better for what they are in all honesty, they sound good at both high and low volume.
I guess you have to ask yourself a question - would YOU make them to tighter tolerances if they was being received by a High-end sound studio?
