I recently did some re-arranging of my system. Some furniture removed, so it gave me the flexibility to move the subwoofer to a better location. In my room, no matter where I put the sub, I have a huge suck-out/dip at approximately 50hz, so I put the sub where the dip was the least severe.
I then re-ran room correction (i only room correct below 400hz), and the system set the crossover at 90hz for the LR, and 80hz for the center, all Sierra-2s. Previously, the system had them all set at 80hz.
