Just caught up, been swamped with school starting.
The reason I was curious to see more graphs is I'm just blown away that you can get this kind of response with one sub in a room that is almost a square. Also, I was curious how much low end (below 20hz) you are getting compared to me and you are absolutely crushing me.
I'm glad to see that Craig and others are helping you figure out your 80hz dip, but man be thankful (I'm sure you are, I'm just jealous since I have to boost the low end so much in my room) for what you have to start with!! Everything from here on will be icing on the cake. How does it sound? I'm betting it sounds fantastic.
