To be brutally honest I didn't expect the YPAO RSC results to be this good/accurate. The Audyssey MultEQ XT32 was, by far, the best EQ I had used, after Anthem's ARC which I still believe to be the best. I expected the YPAO RSC results to be similar to what I got a few years ago with Pioneer's MCACC.
The subs are two Paradigm Reference Seismic 110s and they are equalized using Paradigm's Perfect Bass Kit (PBK). This is a cut down version of Anthem's acclaimed ARC room correction system but dedicated to the subwoofers. The PBK kit comes with the software and the same type of calibrated microphone/tripod as Anthem's ARC. So in this instance they didn't need a lot of correction but it did make one correction at 31.3Hz, dropping it by -0.5dB gain with a Q of 0.5. Please note that those conditions were exactly the same with the Denon/Audyssey graphs in that the subwoofers were already equalized prior to running Audyssey. It is very possible that the YPAO RSC results would be very different if I had two subwoofers without any equalization. Perhaps someone else can try that measurement. In the Manual PEQ image above I did tweak the subwoofers and the front speakers a little bit to try and smooth out one problem area in my large and open concept listening space. If Yamaha allowed the Manual PEQ center frequencies to be modified then you could really deal with the subwoofer frequencies.
FWIW I don't believe in correcting any frequencies above 400Hz as you are correcting the speakers and not the room acoustics. This statement comes directly from Drs Toole and Olive from their combined 80+ years of speaker research. This is why I turned off Audyssey on my Denon and why ARC was so much better as it allowed the user to control the maximum correction frequency.
Right now I am running the Manual PEQ equalization and have zero-ized all the remaining EQ above 400Hz. This is the best sound I have heard in my home with my Revel speakers. Anthem's ARC is better for the room correction unless Yamaha fixes the preset center frequencies issue but the Yamaha sounds better.
Hope this helps.
