Is this an accurate statement?
When you put a speaker into a room, what you hear is the combined sound of the speaker and the room. (With subwoofers it is almost all the room).
When you put a speaker into an untreated or poorly treated room, then the room will add distortions of its own caused by modes and unwanted reflections.
When you properly treat a room, the room will have less malign influence on the sound departing from the speaker.
When you EQ the sound before it gets to the speaker, you have the opportunity to correct for the malign influence of the room by creating filters which 'cancel out' those malign influences, as far as EQ is able to do so - EQ cannot cancel out nulls for example.
There is no such thing as 'pure, clean sound' produced by a speaker, unless you are thinking of it in an anechoic environment. Once the speaker goes into a room it interacts with it. Acoustic treatment can, if it is well conceived and executed, considerably reduce that interaction and EQ can help reduce it if used in isolation or help improve the results of physical treatments if used alongside them.
When you have EQd the speaker/room with Audyssey, and then you turn it off, you are hearing the room's influences on the sound once more. You are NOT hearing the 'pure sound' of the speaker - just the malign influences on the sound (peaks, dips, etc etc) on the speaker: the speaker/room combination.
