Not sure I understand the question but I'll explain what I see and you can infer the answer from it I suppose. So, I'm looking at the PEQ curves when I go into the YPAO manual settings menu. It shows all the curves and EQ corrections applied for each channel individually. There is one for the sub whose frequency range is from 20 Hz to somewhere around 200Hz or so (I think, not at home to check right now). Anyway, it's just a standard EQ curve showing boosts and cuts and their relative Q values. For the sub, it shows a high boost of about 4-5 db with a medium Q up around the 130-140Hz area but that is well beyond my crossover value so not sure it's really doing anything at all. Everything below 80Hz is just flat and shows no correction has been applied at all.
Hopefully that answers your question.
