After just reading another post about someone saying that having the port of their sub too close to a wall made it sound worse. I realized that my port of my Sony SA-WM40 is about 5” away from the wall. Maybe this makes it sound boomier? When I go home this weekend (at college now) I will pull it away from the wall and see if it makes a difference in sound (doubt it will). The main reason I ask this is because I plan of purchasing a HSU STF-2 soon. And I will be going in the same place where my Sony currently is, so the port on it will be pretty close to the wall. And I don’t want this to make the sub sound worse. If I have too I could pull it out from the wall, but it would stick out and look funny. Anyway does this make a difference? And is there a minimum distance that the port should be from the wall? Or does it vary from manufacturer to manufacturer?
