I hope I did not kill this thread, that was not my intention with posting about those graphs.
EQ can be useful, and the opening post here was good. Now, I am curious about how this sounds - how did the eq change the sound, was there an improvement, how did the sound improve.
No I am very happy with the extra information and pushing me to learn more about various graphs.
I am not the most experienced when it comes to reliably noting changes in the frequency response so I don't want to pose as a certified Harmon listener.
But the changes certianly are notable! And it does seem like a significant improvement! It even stood up to blinded testing with my wife changing when the filters were active vs not. So that's a good sign.
The biggest difference I noted was how all parts of the soundstage seem to be on the same level / depth / plane. Before some of the highs felt more 'forward' than the rest. But now the sounds seem more consist in depth if that makes any sense.
I know from reading Dr Floyd Toole that pink noise can be the most revealing, so playing pink noise and comparing pre and post was actually very revealing!
The pink noise was a lot more even and focused in the center between the speakers withuch tighter imaging. I was actually quite impressed!
I have been thinking about toying with RePhase or another DRC that does phase correction as I have heard it can have positive effects... But correcting the frequency certainly helped imaging mush more than I expected!
