I first ran YPAO with subs on both outs, then made manual adjustments after.
Removed EQ on Sub-2 out and set distance to 0. But that distance turned out to be a wrong assumption on my part.
You will want to set the rear sub out channel manually after YPAO with a lot of negative delay.
I know it sounds counter-intuitive, but you actually need to add substantially more distance for Crowson's than you would for a sub.
Not every signal chain is the same so it's best to play a movie with an extended club scene with a low consistent bass line.
I first discovered my Crowson's were off beat from my mains and front subs while watching the Netflix series Black Summer (episode 6).
I kept moving the distance slider in manual mode until it felt correct....ended up at 70 feet
I have a miniDSP and D-501 amp that also added delay to my signal that needed to be accounted for.
More distance = Less delay (I think most Denon/Marantz units max out at 20 feet beyond mains for sub distance)
There was a pretty good discussion about this in the Crowson thread a while ago.
There is a Ton of Great info and very helpful members in the Crowson thread:
Several discussions about negative delays were posted around mid January.
