I just got in a house. Most of the first floor is a large open room, and my TV is next to a wall. My couch is a bit near the TV. I am like 8 feet from the TV. I have no clue where to put my surround speakers. The walls behind are at a distance of like 15 feet or more. Also, they are uneven. Using the ceiling seems out of the question, as I have one of those triangular house and ceiling is like 16 feet high. I am trying to find a way to install my surround speakers somewhere without having wires all over the place. Anyone has suggestions?
