I'm looking for a set of speakers. I'm not concerned about the quality of the sound, I'm more concerned about the punch of the speakers. I want to feel that double-barrel shotgun blast while playing Doom, for example. The louder, the better So I'm not interested in a surround system or anything fancy. I also want to hook it up to game consoles to use it for console games as well, so I don't want a computer-only set. (I don't have a TV; I use a projector, so it'll plug directly into the game console). I don't want anything expensive, either. My upper limit is ~$150 Any recommendations?
