You are not reading the charts right.
A flat curve is not "all". If that were the case, most commercial cabinets wouldn't exist, and Bill's designs would be an utter failure. While you are correct that flatter is better, equalization was invented for very good reason. The OT12 can easily be EQd to match an O10, by mostly CUTTING, not BOOSTING.
While the O10 and O10.5 are better stand-alone bass guitar cabinets than the OT12 and OT212 (on paper), due to their smaller size, flatter response, and little extra bass-end sensitivity, they are not the better choice for those planning a large, scalable system. The OT12/OT212 are much better mates to high-powered subs, such as the T39, T48, O15 Sub, etc.
To clarify ... if you are a bassist, wanting to use a top for small gigs, and the same top with a sub for larger gigs ... it would be more desirable to cut >100hz with the OT12 for smaller gigs than to have to push an O10 much harder than an O12 to provide the desired output to match your sub for larger gigs.
Taking the "technicals" out of the equation, even though the specs indicate that the O10 is a better stand-alone bass cabinet, this "ears only" test revealed that the ears in attendance preferred the SOUND of the OT12. IMO, it was the possibility of discovering revelations such as this one that prompted this entire test. All of the results proved that this testing was definately worthwhile, as it revealed many things that specs did not.
