Thank you for the kind works Bifwynne.
Yes, correct - for those who cannot & will not buy time-coherent speakers DEQX is one answer to the problem. And, I believe the DEQX people were smart when they realized that the room acoustics play an imp part & they incl room correction as well. I think we can safely say that 99% of the people live in homes where the room sucks! Does that mean these people cannot have good sounding playback systems? No, they surely can with room correction - either passive (tube traps) or active (PARC, DEQX, Lingdorf, etc).
Re. DEQX taking into account driver distortion - I think DEQX does that already. You put a mic in front of the speaker & measure. DEQX sees distortion. It does not itemize the distortion - X% from x-over, Y% from drivers, Z% from cabinet, A% from room. How does it know where the distortion is coming from? To it distortion is distortion. When it does a correction for the speaker is lumps all the distortion into one number & tries its best to fully correct it. Then, I believe, you go to the next step & do room correction with the mic at your listening position. And, this 2nd part takes out the other big contributor.
So, as you are playing music, the driver is still distortion (as it always did) but the DEQX correction curve has an inverse function to straighten this out. So, I believe that driver distortion is included to whatever extent the measuring mic can pick-up & whatever is the correction capacity of DEQX.
I'd be interested in others' comments too. Thanks.
