I did some more testing over the weekend. I moved the sub to a number of locations and still did not get much of a response from below 30 Hz. I also looked at the room modes. I got the following using the room mode calc located here:

I used dimensions of: 7 FT height, 8'10" width, and 12'8" length. I had to take some averages of the width and height.
Maybe I'm not reading this right, but if the room affects my response below 30 hz, wouldn't that mean there should be a mode around that frequency and that I would be in a null??
There is probably more going on in the room - tangential modes???
I will post more graphs later tonight with just the sub.
I was also curious about the sub itself (Def Tech Super Cube 2). Would the fact that it has one active woofer and 2 passive woofers cause some sort of cancelation? Does anybody else have any experience with the Def Tech subs and REW?
