I had just finished watching The 5th Element and realized that when I had no sound playing there was a slight crackle coming from the sub. Almost sounded like listening to the ocean in a shell (so to speak). I immediatley get the cold sweats and turn as white as a ghost. After gaining my composure and started thinking logically, I discovered that the little fella had loosened my sub connection to my receiver. Just another very happy DLS owner! Thought I would share.
