Well, first do you know what this sub weighs? Hard to place on my 'listening chair'. Second, if I worry about floor loading, what would a plush cushioned chair smaller than the sub result in? Third, my 50+ years of audio has taught me that the sub needs to be near (preferably between) the main speakers; otherwise a multi-miked viola would have the bowing on the left, the finger work on the right and the bass (maybe) behind me. Most unrealistic.
