Yes, but we also quite often get posts questioning all sorts of things that are quite obvious to many of us. I can hear the bass portion of the sweep so I assume most people can. I certainly found it very easy to hear the difference when I had very small temporary speakers as my Heights, when I was initially experimenting with Heights, and those speakers rolled off at about 120Hz. The Audyssey chirps were very different in those speakers, compared to my main speakers, just as I would accept. I find it hard to understand that the duration of a sound may render it inaudible. As I just asked Feri - what is the duration where inaudibility occurs?
Feri's got that "unequivocal" part wrong. Maybe the chirps played through a corrected system would sound the "same" but certainly not the test signals themselves. But personally at least, if I had blown drivers, I think I'd detect it with the chirps, at least for a "per pair" basis..
I do believe the chirps, post-Audyssey, may well sound the same. But that isn't what was under discussion. The issue of blown drivers is just a red herring.
