Lol.
The Revel F208s exhibit a similar bass hump. They are reguarded as reference, and not only for their price. So many variables in play. I messed with my setup (a lot) and viewed real time subjective response as objective levels changed. The M3/F208 response is where a balanced and pleasing sound ends up in room. They are set up that way so a sub is not a strict requirement.
With a dead flat response I'd be willing to bet most people will prefer a slight bass boost of 5db below 100ish hz or so for 2ch. This is supported by Sean Olive's own subjective group tests.
That guy really needs to put hands on stuff and measure and listen for himself. He frequents the Stereophile comments section. A gem indeed. A big, lumpy, brown gem.
