Unless something has changed in the latest version YPAO will not EQ a subwoofer. My understanding is that not all versions of Audyssey will do sub EQ either, XT32 does for sure for up to 2 subs but I'm not as clear on the other versions. MACC and YPAO do not, which is why Antimode as a stand alone EASY option for sub equalization makes sense for some.
Brian323, you should get acquainted with the "sub crawl" technique for now to place your sub and then just listen and make up your mind, I'm sure you'll like this sub based on what I've read. Once the upgradeitis sets in, get yourself a mic/REW and go from there.
Audyssey MultEQ, MultEQ XT and MultEQ XT32 all eq subs (but as one even if multiple subs, my understanding is you would need Audyssey SubEQ implementation and appropriate avr with actual separate sub pre-outs, rather than internally-split single signal, e.g. the Onkyo 818 has MultEQ XT32 but does not have Sub EQ and treats both sub preouts equally, as it's basically an internal y-splitter). Their comparo chart:
