Are you a Subwoofer abuser?

The subwoofer can be fantastic or a monster. In my case I use my sub very conservatively. I don't want to ruin the mid's and top end w/to much bass. However I found a certain segment feels the bottom is the most important part of the music. If you don't have big bass the system isn't correct. How do you set your sub? In my case it's fairly conservative. It's basically to fill in the bottom end w/out heartening the midsized and top end. Any friends that can't get enough bass?
