The graph shows that your subs low end extension is ~45Hz. That would be consistent with PC based speaker+sub system. The signal as it rises from 35Hz down to 15Hz is basically noise exacerbated in the plot by the inverse meter calibration file.

But overall the response ain't too bad. You can see how the corner helps the bottom end, but it also suffers from a dip at ~150Hz. I would think by moving the sub around you could get a fairly smooth response. Treatment is ineffective at frequencies below about ~100Hz and so most of your peaks in the plot could be handled by placement, given that they aren't that bad.

Anyway, you obviously know how to use the program, so the HT room is next..
