My goal right now is to determine the room accoustics and try to calibrate REW. Am I going about this all wrong?
I a bit confused what your goal is...

Generally, REW is first used to test a subwoofer(s) alone, without mains attached. The range used is usually from 15Hz-200Hz. This is the area where equalization is most effective (after proper placement of the sub has provided the best overall response). Above 200Hz, up to around 500Hz, room treatments are quite effective. REW will begin showing a lot of comb filtering in the graphs at and above this range, so you need to apply the smoothing feature to see the overall trend of the response. This is what you're seeing in your graph above ~200Hz. You bottom end is trailing off as expected with the speakers you're using.

Is you intent to position the speakers for the best response, or are you trying to apply treatment?
