Update:

Using my ears, the EQ, and a simple iphone RTA app, I isolated my missing frequency to a pretty narrow band centered at 160hz .......my MS-8 crossover frequency....hhhmmmmm.....

in a traditional system this would mean that my woofers are out of phase with my mids....but doesnt the MS-8 compensate for that when it runs the first time alignment sweep since the woofers are on their own channels?

Also I was able to boost it using the EQ, if it was a true phase issue I wouldnt have been able to do that.....

But I swapped phase and its much improved but still a few db down at 160.....oh well, close enough!

Maybe it was a bad calibration, it can be a little noisy around my office where I was calibrating this morning.
