I have just finished up a sub build and have more deep bass than ever before

. Problem is when I re-ran the Audyssey program on my Denon 3808 it kills my deep bass.
Do you guys have any suggestions on the best way to fool Audyssey so it won't mess with my deep stuff?
Here is what I am talking about. All measurements taken from the same position.

So I added some filters thinking I would get better results from Audyssey.

And this is the Audyssey result.

I would have guessed that Audyssey would not have touched anything below 20Hz, but how wrong I was.
