Room Correction: Should I disconnect my REL Subwoofers before running room correction?

I have a NAD C 658 Streamer / Dac with Dirac room correction.  I have a pair of REL Subwoofers R 528 connected/ integrated to the mains.  I’m wondering if it would be best to run room correction with the subs connected or to run without and then tune the RELS after.  
Equipment:
Modwright150SE
Dali Euphonia ms-4
NAD C 658
REL R528 x2

Not if it’s being correct as well with your mains. leave the xover on it up full and the level at 1/2 and the room correction should take care of the rest, even the phase if it’s a good one that uses a microphone when doing it's FR sweeps.

@George.  To clarify : So when running the RC, I would set the sub volume at 50% and the frequency at 100%? If I am understanding that, would I then leave the sub at those levels when playing music?

Subs are the most important part of room correction. :)  Leave them on.

Did you buy the full version of Dirac live or are you running the  free version that comes with the NAD? The free version only goes from 20hz - 500hz so I would leave the subs on,  doesn't the instructions tell you how to set the subwoofer?
