Learning REW as I see a few people are. Subwoofers seem easier (possibly because Minidsp and filters). I have not figured out with REW and Windows 11 to measure the center but it is upgraded as well.
Measured from listening position (several times but they are all pretty close to the same). Media room is treated with acoustic panels and base traps in all four corners. Smoothing is 1/12 (per YouTube video suggestion).
