Try walking around the room into different corners and such. My room is unfortunately square, it's basement, so a lot of concrete and it has very little in it except a couch and a coffee table for now. There is a big shelf full of AV gear but fills in the one alcove, adding to the squareness, heh heh.
Anyways, I have huge differences in bass impact depending where I stand. I have to turn up the sub to get 75 db in the normal seating positions but should you sit in a rear corner for some reason, you would find the sub volume almost too loud for comfort.
I'd wait until you get all of the rooms furnishings and stuff in place before you play around too much. If it's staying as is for while, calibrate to your listening position now but remember to do it again once the room has been changed to any degree.
