I've kept trying to figure this out without much luck. I've noticed that for whatever reason - the measured response of the left channel (subwoofer plotted in Red) is a mirror image of the Radio Shack microphone calibration (plotted in black)that is applied.

I noticed that if I cleared the microphone calibration, the test of the left channel matched that of the soundcard with flat response. If I enabled the newrs.cal file, I ended up with the inverse plot shown.

I've also attached my soundcard debug file.
