Needing help in sub placement. Its in the basement in a pretty large area. The back room is not usable for movie watching so I had to do where it's at right now. I was wondering if anybody has any insight or idea where I could put the subs. I have 4 12" that i would spread around the room. i already played with various positions and 1 and 2 sound the best with 3 and 4 right behind. 5 is ok but nothing special. Left, next to the couch is not bad either.It just doesn't have any impact at all, and I'm lost at what to do. The subs are sealed right now, but I am planning on going ported.
