I'm with you Mark. To me, the graph still has the same dips and peaks, everything has just been dampened.
I have also been researching some treatments for my room. Don't know what just yet (DIY or professional), I am trying to decide what is "needed" without absorbtion overkill.
I'm thinking some absorbtion panels up front at the 1st reflection points between the speakers and the listeners. For me this is just 2 panels, unless I put 1 or 2 more on the ceiling. I have decided not to do any panels in the back of the room (between the side and back surrounds). Here you don't want absorbtion of the mid and high frequencies, but rather diffusion for a more spacious surround effect.
There sure is a lot to understand about room acoustics when you are new to it. I have done a lot of reading and still feel confused
