I've used the Denon's auto EQ to setup my sub. I find it does a pretty good job. However, for some reason it never comes close to the actual distance. For example, it estimated my sub was 18 feet from my listening position instead of 9 feet. However, to my ears, it sounds good and the level seems appropriate, so I don't argue with it.

I recommend using the EQ as a starting point. If it doesn't sound quite right (too much or too little)...you can always adjust it manually to fit your preference.
