I lent my sub to a friend to experiment with. I went to visit him and it sounds like total crap in his room. We tried placing it in a few different spots and really, it still sounds like crap. I was wondering if the ol' put the sub in the prefered listening spot and crawling around until you find the best bass response would work in a room that's L shaped. The vertical part of the L being the only part used for HT, the couch at the bottom. If it does, I'm going to tell him to try it.
