I know that the question is out there for brwsaw, but I've got 2 large ported subs up front behind my screen. They don't come across as "boomy" at all, but even so, I plan to some day add a 3rd sub, to the back of the room. That one will most likely be sealed if possible to add just the "punch" factor. I also have Bass Shakers in each seat (with their own filters so that they only "play" below 50Hz so that they aren't vibrating with all of the stuff between the normal 80Hz sub/LFE and 50Hz) that add to the tactile feel.
Can you ever have too many subs? LOL
