Decided to put the subs in 17hz mode and rerun XT32, and then level match with REW and the certified mic. XT32 does a pretty good job, found the subs to be about 1.5db low. SPL meters really arent accurate here.
By going to 17hz tuning I gained 10db at 16hz and 20hz, and kept pretty much the same output from 25-80hz. Gonna be curious to see what the new sub looks like tomorrow after its all calibrated up.

Subs in 17hz tuning
I have a null at 22hz, not much I can do about that right now. All in all, when you take a before and after, I think XT32 does a good job boosting and knocking off peaks where it needs to.
When I have time I am going to move my subs back outside my mains and try and change the dip at 22hz and 150hz. Room sim seems to think this will help, so we shall see.
