Hi Powerste Your situation is similar to mine. My rig is in a loft. Quite small and with no back wall. Everything sounds ok but there are reflections from the large window directly behind the open area. I thought of some room dividers I saw in a JCpenny catalog. These dividers have a cloth type curtain that can be replaced(they are on small rods) They also come in different lengths. They can folded when not in use and should help my reflection problem when listening. Just a thought and I hope it helps.
