[IBorBox]

Thanks. The space above is not used because it is exposed above the TV when the TV is slid back in front of the opening. It was originally used as a closet that was for items used infrequently. It had a Bi-fold door for access. So to make the final look of the IB stealthy, I cut the door in half across and rigged up a mount to hold the upper half of the door in placer. From all practical positions in front of the TV you can not see the IB. Anyway, the output is by far more than I need.
