dBe is right as rain about symmetry. And, please, pull your speakers more out into the room. You do like 3D depth of field, don't you? Bout 52" from the face of them to the wall or as much as you can manage. Can't see the other end of your room but you do not want to be sitting flush against the wall. Your seat, too, needs to be out from the wall behind it. How's about doing that and then re-posting with your impressions. Damp that TV screen when listening, too, with a mattress pad- of the kind that look like egg crates maybe- or something.
