As per a request, I attempted more measurements of the SPL response at Spark volumes of 10-35 to determine how the lower bass frequencies volumes are adjusted.
Caveat - At this volume level there is little output that I can hear and it is approaching ambient noise levels and can be affected by external sounds. The mic may also be reaching it abilities.
Each volume sweep is at least an average of 5 with many more taken the lower the volume, though I am sure the result could change if performed again.
The resulting average has then had 1/6 smoothing applied to ease the comparison.
I would tentatively say that, around 25Hz, it appears the volume stops dropping uniformly by 5dB.
