A quick question to
@amirm
When looking at this plot:
View attachment 101579
we see that the distortion (@ 30Hz) has increased from 2.5% to 45% with EQ applied.
Would it be safe to assume that the average level in the bass, due to the +9dB bass boost (I use +3dB bass boost at 30Hz but lower the middbass hump) would result in 104dB SPL at around 30Hz ?
If so, when looking at the plot below one would expect to see around 5% distortion at 30Hz (which is as good as inaudible) and not 45%.

Where is this discrepancy originating from.
Not fully comparable but below my distortion measurement (hardware EQ) at 90dB SPL (so including bass boost)

It shows around 1.5% distortion (2nd and 3rd combined) at 30Hz.
