I know this type of thread has been posted many times but all the situations are always different. I have opted to place the TV in the corner with the 2 front speakers either side and stand mounted,diagonally opposite will be the seating position and behind that is the room window which is 10ft.wide plus curtain width will make it 12ft. Should i wall mount the speakers on this wall behind the seating position at the 12ft. pitch or should they be stand mounted and placed either side of the seating position? And if wall mounted what would be the best height to have them on the wall,seating height or higher and angled down and in?
