Tried searching and havent found any good sources yet so turn to the experts. I have a number of sonos units and have just got another one with a view to setting up another room. This room is not regularly used and is purely to chill out. It measures 2.5m by 4.5m and i intend to use JBL ceiling speakers. I will be sitting along one of the longer wall, so where should I place the speakers for optimum listening. I appreciate that ceiling speakers wont be as good for sound as big boxes but I have a seperate room for that.
