Get a decent sub because it makes a difference. I spent $400-$500 on mine about ten years ago and it hasn't missed a beat in this time. The amp in it has enough power to cover everything from explosions with authority while subtly dealing with the nuances of music. It was designed to serve both uses and does a fine job doing so. If all you care about is music then pick a sub designed only for it.
I was so impressed after researching HSU that I bought one! I got the VTF-2 MK5 Subwoofer. Thanks.
