I have a small 12w x12 L x10 h office, but I have a 6 foot pocket door on one end. I have a small system, with bookshelf's. Its rather interesting to hear the difference in sound when that pocket door is open, the bass when that door is closed vs open. ITs better but not even close to ideal. The walls and ceiling in that room, when it was built have QuietRock 545, which seems to help. But yes, if this was my only audio room then a square room doesn't get it unless you are a headphone user.
