I think his impressions have more to do with his imagination than reality. They are so much alike that the differences should be barely perceptible. Same driver, same design, same ports, almost the same amp. The only thing that is different is the enclosure size, and a few settings in the amp to reflect that, and that is only going to change the tuning point, I don't know how that would affect bass above there. If you are expecting a certain difference when you are listening to them, you could end up hearing it regardless of whether it exists or not.
