Here are the two most common configuration problems that people have:
1) What did Audyssey determine to be the sub channel level? If a very low negative number, turn down the gain (volume) on the sub and rerun Audyssey until it's close to 0db, even if you have to rerun Audyssey multiple times and turn the gain down very low. This optimizes your sub to make best use of the signal coming from the receiver. Get it to say -2db, and then afterwards, you can bump up the channel level on the receiver 2 or 3db (don't change the gain on the sub) and see if that gives you the bass you are looking for.
2) Audyssey will often set your main speakers to large or full range. They should be set to small and you would need to set a crossover for the sub to work (try 80hz).
Make sure both of these are taken care of, and I would imagine that your sub should sound better.
