Hi Worfzara,
In the listening tests, which go on for several days and involve not just me but other Axiom staffers, when the numerical ratings of the speakers under test reach the level of little or no significant difference, then the phrase "similarly good" applies. That means that while two speakers may not sound absolutely identical, any differences that emerge tend to depend on the type of music being played.
When you place a speaker into a wall, the one consistency that emerges is a slight loss of bass. That's true of the boookshelf T models, and to a lesser degree, of the hybrid in-wall/on wall models. In the tweaking of the spectral balance, Ian has compensated in the design for any coloration that may occur. I've rejected various models based on coloration, and Ian goes back into the anechoic chamber and adjusts the frequency response, crossover, etc. until in the listening tests the speaker meets the "similarly good" criterion.
Regards,
Alan
