Oh, another quote.
One of the guys who watched the movie with me who is somewhat audio inclined came to listen for a bit.
His comment: "Dude, the whole COUCH was shaking during the podrace"
I was sitting on the floor on a beanbag, kinda close to the sub. It seems the sub gets amplfied as you sit farther down the room. I might try moving the sub a few inches, with what I have.
Edit: I was able to turn the sub sideways under my desk and push it as close to the wall as possible. Seems to have killed the dead zone. Since the woofer is in the front of the HSU sub, having it oriented towards me left about 2 feet between the woofer and the wall, creating dead zones.
