Hi!
Came to think about this.

Comb filtering results in equal amounts of added pressure and removed pressure. If there's a sharp dip, there's also a sharp peak somewhere. The peak can be EQ'ed. Since SBIR doesn't move with listening position, this seems like a good place to use an EQ if that's so desired. Perhaps that's what SAC wrote above and I'm too dense to realize it. :D
Been thinking about this room EQ thing. What about the impulse response? Surely adding an EQ to correct non-minimum phase behaviour will make the impulse response worse..? Is this a problem in real life?
