Subwoofers remind me of a story... A guy came over to my house. He had a subwoofer in the back of his rice burner that shook the car. It was nothing but pure distortion! I took him inside to my home stereo (my roommate at the time worked for an upper end stereo shop... thanks Dan!). Anyway, I put on a DDD
Telarc CD (which is about as good as a CD as you can get). It was beautiful. His mouth about dropped at the difference. Subwoofers are okay, but clearity is where it's at.
Now when my neighbor comes up to a car at a stop light that is "bothering him", he drops his hand on his XJ's horn until he can't hear it, lol.
