I bought a UMIK-1 calibrated microphone. Mine came from Parts Express although you can get them directly from MiniDSP or Jeff Bozo's company. It costs 90 something dollars delivered. I used REW to do measurements and generate PEQ filters and typed the parameters into the parametric EQ in JRiver. The improvement in sound was very noticeable. Electric bass and female vocals picked up a lot of definition and detail.

My system has a pair of LS50's on 24" stands about 20" in front of a big wall unit which is 18" deep, 36" high and 10' long. The speakers are 7' 4" apart and the listening position is at the tip of an equilateral triangle. The couch is 2' from the back wall. There is a 12" down firing sub off to the right side and outside of the triangle. The room is a finished attic with an irregular ceiling and wall to wall carpeting.
I took measurements placing the mike on two old speakers covered with a small wool blanket. The mike was where my head would be. It faced straight ahead at a spot midway between the speakers. (note: the USB cable supplied with the mike, is 10' and was not long enough. I had to use an extension.) The regular config file was used, not the 90.
Measurements were up to 200 hz (400 was tried, but made no difference.) I used variable smoothing and generated filters for "full range loudspeaker". The only other change was to limit boost adjustments to 3 db. If changed to 4db the results were very different.
Is there a better way to do this like doing left, right and sub separately and combining them? Should I point the mike directly at the speaker being measured?
Perhaps I am lucky, because the music sounds much better now...
