That is cool. It is saying that with my 2 subs I hit "reference" level of 4.0 at 20hz, and a score of 3.0 at 16hz. I would need to go from 2 to 4 subs to get reference level at 16hz, but would be "above reference" at 20hz.

To me it is more than that though, it is about smooth and even bass in the room. smile Not just louder and deeper.
