How was this arrived at? It would seem that the Olive target compared to the SBAF compensation would be upward sloping at 1db per octave with the addition a few db extra from 2kHz onwards based three factors: The Olive curve below. The SBAF curve is supposed to be perceptive neutral. This meaning flat on-axis at 1m away which typically translates in-room response to a 1db downward slope (either from 20Hz or 200-300Hz, the latter being the B&K curve) Note that loudspeakers equalized flat in-room (per below) will sound fricking bright. Therefore the Olive curve below if applied to speakers in a living room would be upward sloping (fricking bright) with a fuckton of bass below 100-150Hz.
