I have an L couch on back wall fitted to left corner and and sub in the other corner. Recliner is a bit forward of right arm of couch and 3-4ft from sub next to right wall angled. Listening will mostly be from these positions but occasionally will move out chair forward and centered in front of couch about 4-6ft from back wall. Side wall to side wall is about 12ft with 8ft ceiling. Need in wall, ceiling, or high corner placement and height advice. Stands out of the question. Looking at 6.5 or 5.25 two-ways under $100 like some Dayton's. Not looking for optimum, just a good compromise for being against the wall at times. Thanks!
