Well not exactly, Tex.
I like to keep it simple and usually lump audio irregularities into either of two broad categories, physical (ie FR) and time domains(ie phase). Yes most can be expressed as functions of the other but for purposes of a discussion of equalization and acoustics its hard to correct one without damaging the other. That's why after a point applying more equalization to get the flattest FR curve actually sounds worse since phase anomalies are increasingly audible.
Those Audessey programs not only mess up phase but they also don't provide the smoothest response. In fact most of the time they make the 400hz and lower zone less linear. Behringer specifically warns about this in the literature accompanying their equalizers. Funny how Audessey never mentions it.
On your Axiom marketing conspiracy theory...
...just about every product these days has glitches, right? Not that makes it acceptable, but it does reinforce the importance of excellent service in whatever gear you buy these days.
