Hello! New user here hoping to get some advice and guidance. I am currently starting a project to finish my attic and plan to make it a combined rec space and home theater. The floorplan is a 38' x 28' colonial so a 45 degree roof pitch up to a 7' flat ceiling with a staircase splitting the room roughly in half. As such my proposed space will be roughly 20' square. My tentative plan is to have an electric screen recessed in the new ceiling at one end of the room, when down it'll cover the window, I'll add blinds if that is not sufficient light blocking. I aim to have projector wiring in the ceiling and initially use an Epson HD projector that I already have (throw distance etc to be determined). While I'd welcome any guidance people care to share my main dilemma is around wiring for now. As the space is not yet framed I want to make sure I have flexibility for wiring and surround sound. Should I assume speaker connections in all four corners, a sub and a center connection below (or above?) the screen? I have not researched or decided on a receiver / speaker setup which will probably be clear from my questions. a) Should I run 14/4 from a corner location where I'd locate equipment, will that be sufficient for all M may want to do or should I consider conduit through which I can snake wires later? b) Are there advantages / disadvantages to planning in wall/ceiling speakers vs wall or ceiling mounted? c) Should I put receptacles in proposed the speaker locations to provide flexibility for later or just leave my wires in known spots behind the drywall? If it matters I don't see this being overdone, I'd given the cost involved in the initial finishing I'd likely start out with a reasonably priced home theater system but tend to think it makes sense to design with flexibility in mind for the future. While I am familiar with regular projectors, wiring etc. my only real home theater experience has been with an Onkyo set I had a number of years ago in an unfinished basement. Thoughts on an initial setup for sound and switching would be welcome, I'll likely want to have a Roku and a cable box connected and maybe two outputs so I can choose TV/Projector as circumstances dictate. Very much appreciate any guidance and tips! Chris.
