My sub is to the right of our seating position in the corner where your fireplace is. It is an 8year old enclosed style that I bought from Costco.It shakes the house which is good for HT, but is to boomy and sloppy for good music. It does a decent enough job for now. My fireplace is in the corner where your TV is going, My tv is on top of the fireplace. The fireplace was built out so the "mantle" area was large enough to support a TV. My 6th channel is above the listener as you had said, it sounds fine, don't worry.
