      If the subwoofer is too quiet, try the following: First, the source material might not contain much bass, so try playing source material that contains more bass. Second, bass sounds might be getting cancelled out by standing waves. Try repositioning the subwoofer, or break up parallel wall surfaces by placing bookshelves or other large objects along the wall.
