Curious about what’s happening below 40hz. It’s pretty flat going down to about 100then rises going down to 40 and then it’s a cliff. I know your speakers go below that and can see some in the graph but that looks very odd. Well, the reference level is only about 70dB. So the YPAO FLAT is down about 5dB from 15-35Hz. Not exactly off the cliff. I played some more afterward on manual PEQ. Bass is a little hot, but that's my personal preference. :D
