I am curious, how much does extra cubic feet in a room affect sound? I can't notice much/any difference between when my room's doors/windows are shut and when everything is open. Although it may be because my room is not really insulated much at all (you can hear sound pretty well through the closed door and sometimes even the siding rattling a bit outside without a sub and inexpensive speakers).
Is it mainly ceiling height, distance from speakers, and the walls that are primarily reflecting sound, or what?
