I'm not really getting anything below 40hz right now with the 7's in my office. I'm not sure if this is a cabinet issue or room issue. My super scientific rat shack meter shows a bass dip at 80hz and a big dip between 600hz and 2k pretty much anywhere in the room. Right now I'm using the 2pi towers in place of the 7's and the towers seem to have more bass in this room.
