We are thinking about getting a larger sofa for the media room. We have two PB1000 Pros. One is in the corner on the right side as you face the TV and the other is not quite in the corner diagonally from that. There is currently 2” of space between the molding and the sub and 2” between the sub and the sofa. Would we likely experience a drop in sound quality if we had the sub touching both the molding and the sofa, with the sub forward towards the TV? Thanks.
