This isn't to argue against room treatments or sensible speaker postioning, let me be clear.

According to Onkyo, my receiver includes "Audyssey 2EQ, Audyssey Dynamic Volume, and Audyssey Dynamic EQ". I have forgotten exactly what each does. In my case I have 3 three microphone positions that instructions say are supposed to be different listening positions. It does seem that the calibration process takes into consideration each speaker for each of the three listening postions. I.e. somehow each channel is corrected to reflect some sort of average of the three positions. Anyway, it works pretty well.
I set up a friends 508 several months ago, and it does sound great.
MY receiver(Integra 6.9) allows for up to six positions. According to my manual,
the system detects the speakers connected, their properties, bass management crossover
info, distances, etc. It then adjusts for the room in freq and time domain, so it
would seem that "room treatments" would actually lessen the effectiveness .
DYNAMIC EQ maintains proper octave to octave balance at any volume level.
SO I wouldn't bother with room treatment with this type of eq.
