Hi, Im currently building a home cinema / summer house extension(later being the birds idea) The rectangular room is to extend from our existing sitting room. the dimensions are 25ft * 16 ft so its going to be nice and large. I have all the av gear (apart from plasma etc) to fill said room with the latest sound formats and construction of the room is just underway. Foundations are down and the footings have just started. The floor is to be a concrete beam and block suspended one. My first question is, how do I conceal all the cables? The tv is to be hung on the long wall but the screen is to be lowered from the ceiling. My other question is How do i set up the speakers to accomodate two different listening positions?
