The soundcard cal looks fine, but I'm confused about your statement, "and the mic level is at 25".Notes: When calibrating the sound card the Sweep level was at -12.0. The speaker level is set through the control panel at 100 and the mic level is at 25. Sampling was at 48K Hz.
Question: Is the level setting ok?
What mic level? You should be using line-in, not mic-in.
Yes.The Sweep Level was at -18.0 dB FS. The speaker level was at 100 and the mic level was at 100. The receiver volume was at 20. The SPL meter was hovering around 75. I'm using the right side input and out on the soundcard, going into the receiver's L & R AUX inputs with a splitter.
Question: Am I on the right path?
Well, once REW created the filters for you, I would manually add and alter at that point to get rid of the peak you were left with at ~50Hz..This is my measurement with the filter in place.

Does any of this look right?
