Ok so I understand that generally its a big no no to put a subwoofer in the middle of the room. I live in a dorm room and will for the next at least year and a half. My Plan A is getting a sonotube for a 15" my Plan B is a box around 7-8 cubes. If I go the route of the box then I would want to put it underneath my bed which takes up most of the room. There is close to 3 feet of clearance underneath my bed. Yay or nay?
