Danmar123 - I have a MK mx 125.2 push/pull for my sub which is set up behind the couch, really adds to the madness.
:^)
I have found behind the couch or other room boundary near to the listening position, is an excellent location for a sub especially when matching up with ESL speakers. Sometimes, not the most aesthetic depending on the room layout. If this is a problem it can be hidden / disguised when not in use by covering it with one of your wife's favorite knitted quilts, and her favorite wedding or family portrait on top.
