I have the Energy S12.3 subwoofer, http://www.energy-speakers.com/v2/p...-page.php?id=38 and am having a problem in that the sub is in my viewing area. The sub is downward ported, driver forward. If I leave it standing up normal the subwoofer runs 3 inches into the screen. I was hoping I could lay the speaker on its side, as the side width would work fine. If I position the port against the wall where the screen is, it seems like it is essentially still a down ported sub. What would happen if I laid the speaker on its side, with the driver facing forward, and the port facing either left or right wall? Would it make the frequency response not as low? Any suggestions?
