Well, Randy, about the only comment on the graphs is that the peak around 38Hz and smaller one around 57Hz appears to be the room mode relative to the 30' dimension. It also appears that the mode wasn't significantly affected by the changed sub position, and if anything the second graph appears to be a bit worse overall.

Possibly, as you inferred, the advice for you and Mark Johnson(he of the room that sucks)should be to add watching the making of room effects to making sausage and laws as being things better off left unseen.
