there are wires in the walls connecting the entertainment cluster to wall jacks. the wall jacks are behind the curtains about 6 inches off the ground.

this the the first floor of a two floor house - so there is no attic.

also - i spent a considerable amount of time and effort to remove the popcorn off the ceiling, so i am not entirely keen on messing with it. maybe i'll post a photo of what it looked like before (i took photos before buying the house which show what it was like).
