It is on Floyd Toole's book. A flat speaker in near field will measure linear descending tilt in the far field because of frequency directivity. Mids start attenuating to the sides until the highs are forward facing only, and the bass is omni directional. When everything is reflected in the room and reaches the listening position, is tilts down.If you're over 40, you want to boost frequencies above 10kHz as well. I don't see the logic in the Harman curve where they attenuate the higher end.
