The level has nothing to do with sub level in this case. The major reduction overall is way above the sub xover - plus there are still 15-20db swings in the sub range and a general overall dip in the 2-400 range. Consider a large solid absorber on the floor behind the couch, a minimum 4" thick absorber on the rear wall behind the seating position, and playing with the sub/mains position in the room.
