Okay Steph, my first thought was that maybe you were sitting in the middle of the room in a bass null, but as much as I was able to follow that isn't the case. Maybe can figure something from pictures/diagram.
You apparently really like your bass, so let me ask about the situation when you did use the sub and calibrated its level. Was the measured calibration inadequate and did you set the sub quite a bit "hot" to achieve a more satisfactory effect? As you may gather, I'm exploring the possibility that the elevated bass level you prefer isn't going to be supplied by any main speakers.
