I think I may have developed some significant decay improvements. I wasn't quite expecting this but I guess when using the mini dsp to cut it REALLY helps present Audyssey with a much better and easier job to do. In fact unless I am missing something here this could be a significant reason to a growing number of users of the mini dsp and Audyssey partnership. I remember a couple of you posting pre and post Audyssey waterfall and spectrograms. You're EQ lines were much better but at the sake of bloated decay times.
Big disclaimer here. I have always used one of the PEQ options called "peak". Now I selected an option this time called "subwoofer EQ". It had an different and desirable effect on the EQ line. For example if I had a -8db cut selected with a Q of 3.5 and selected "Sub EQ" and then "Peak" with the same -8db gain selection and the same 3.5 Q setting it made entirely different looking EQ lines. The peak option had a more singular type effect and the Sub EQ a broader effect if that makes sense. But it obviously and unexpectedly had a effect on decay. If anyone is interested I would be willing to post direct graph comparisons of the frequency response and waterfall/spectrogram with just the peak and sub EQ selections changed to get a DIRECT comparison and what it does.
Here is the baby...
This is my waterfall after the other day when just using the peak cuts. An important note is both times I had PGM 2 on the submersives selected, and a low shelf filter engaged. The biggest difference is the before/worse graphs I had an 80hz crossover and the better graphs have an 150hz crossover.
This is the waterfall after using the "Sub EQ"
Here are the Spectrograms.
Before with peak EQ cuts
And after with Sub EQ cuts
And here are a couple waterfalls before the low shelf filter was engaged. I think I will end up with a shelf filter that is about a 6db up at 30hz over 100hz rather than the 10db up I have now. I thought the decay times were pretty dang impressive! I could way off base with everything but it seems legit to me. These two waterfalls are the development of the house curve. The one you seen above is the final.
We are talking basically 200ms almost to 30hz!
I don't even have a room treatment built yet...Edited by jlpowell84 - 11/12/13 at 12:14am
