Run YPAO without a Sub (knowing beforehand what YPAO did to distance and levels)... then, after YPAO runs, manually add a Sub... and then use miniDSP or other EQ solution to EQ the Sub... make sense?
I will be receiving next week a used the Audyssey equivalent of the AS-EQ1 (their version) that I found at a great price. I plan to record the Sub Level and Distance YPAO already calculated... and then use the approach mentioned with a 120Hz crossover applied at first so the XT32 Sub Auto Eq do its things up to 120Hz so I can then adjust the cross over setting on the AVR between 80-120 as I need... makes sense this taking into account your miniDSP experience with YPAO?
Interesting idea. I've never tried this approach because I barely do EQ above 100hz anymore. Fortunately for my room, the RSC filters weren't really needed as I just needed to tame the 5khz - 8khz region with a few -db cuts. A subtle adjustment just to get that sweet spot for me.
That said, I don't think the filters that you can set on the minidsp (or the AS-EQ1 in your case) are the same at all for YPAO. I mean, the resolution is different already but I'm unsure of how big of a difference that makes. If you don't hear any abnormalities within your soundstage, I think your idea will work fine.
For reference, my setup with YPAO is fairly simple;
1) Use YPAO and let it calculate delays/distance, levels and the initial PEQ pre-set it comes up with. Just for fun, the Natural pre-set actually sounded very decent to my ears.
2) Bass manage by setting my crossovers to 90hz for all channels, I know 80hz is the general standard - but 90hz is simply just the sweet spot in my room.
3) Use REW and a UMIK-1 mic to measure my room/system response; check where the regions are the most problematic - for my case, at 31hz, 45-55hz and 5khz-8khz.
4) Use YPAO manual without copying any of the PEQ presets, with the info I got from REW - do some adjustments at 5khz-8khz and just a slight bump at around 300hz.
5) Connect minidsp, EQ my subs - particularly at the 31hz, 45-55hz and just a slight cut at around 21hz.
It obviously did take a bit of time to learn how to use REW, but honestly it was fairly simple - just a lot of options to go through. I know I can eek out somemore from my system by setting custom filters, but I haven't found the time to do so.
