Hi Bruno. Dean would be referring to the frequency chart of the M80 vs some other brands as some manufacturers deliberately attenuate the higher freq's because they feel, well, that's what their customers prefer. Co's like Axiom, Paradigm and PSB, for instance, will try to maintain a flat freq response right up to 20khz as that is their design philosophy. Their testing has shown that this is preferred by listeners to the "rolled off" or attenuated highs that Dean aluded to.
(don't mean to butt in and answer for Dean, btw. Okay, yah I did...)
