Most concepts of home theater speakers insist that speakers in a good system should be 'timbre matched.' Meaning the tonality of the speakers should be identical. Even THX includes circuitry in some receivers, etc, that attempt to do this. What I'm wondering is this; Since the hearing of a person is different when the sound comes from front, back and sides, wouldn't it make sense that if we wanted speakers to sound the same as each other, they'd have to be very different from each other in order to compensate for human hearing particulars? In other words, our centre, left-right fronts, side surrounds and rear surrounds would be radically different in order to maintain the same tonality to us?
