When you get a reduced room, the frequency band (from zero up to the Schroeder
frequency) is getting more broad. That simply mean that you will get a strong
spectrum fluctuation within this band but that's caused by the room resonance
which could be more or less damped. Above what we call the Schroeder freq.
there is so many resonance (more than 3) at a single given freq. that you may
move to an assumption of reverberation dynamics. Schroder freq. is thus givin a
limitation between low freq. modal dynamics and high freq. reverberation
dynamics.

As a more clear answer (really? ;) ), small room imply strong changes but this
is not caused by the same principle, as I said, its about resonance.

Selon Jay Smalridge <inadaze@mac.com>:
I guess the room would have to be small
> to make any significant change, but does the principle still exist?
