Assistance with RT60 Decay, Frequency Response and Audyssey One

[heboil]

Hi everyone -

I have been running my HT/Listening Room for nearly two decades with DIY sound panels I made. It is a pretty dead room with the panels, the acoustic drop ceiling, the carpet & sofa etc. The front of my room is/was treated withe my DIY panels. The back of the room, not really treated but lots of media, shelving and collectibles. I just recently got into REW and I have been working to try and move speakers around and adjust curve to flatten my response (two sub used). I have a L+R graph that I can show here... with most of my acoustic treatments removed.

Curve Edited in MultEQ

My RT60 Decay looks like this for L+R:

My RT60 Decay looked like this for L only with all my treatment in place:

So then I tried Audyssey One. My frequency response curve is kinda ugly, but the RT60 Decay is much cleaner... but still dead. Thoughts?

I can’t answer your specific question, but I had the same issues with FR after A1. I couldn’t be bothered to try any harder, as the sound and plots were much better with MultEQ-X… Maybe I was going something wrong with A1, but I had low bass and boosted mids…

I am "quasi-convinced" that Audyssey is affecting RT60. When I sweep the room without Audyssey applied, my RT60 is around 200-250 across the spectrum (and flat). But when I turn on vanilla Audyssey, my RT60 gets weird spikes (up to .800 or .900). And that is "vanilla Audyssey"... no house curve, with or without filtering at a frequency.
