Sumiko, the distributor of REL Subwoofers has a set up guide for subwoofers on their website.

I've found it very informative and easy to understand. I'm not sure if it's the best for other sub manufactures, but its a good place to start. They do recommend track #4 on the "Sneakers" soundtrack (Columbia CK53146) because of its repetitive bass lines to make setup easier.
Hope this helps
