Yes, the initial dip at 200Hz would be the same at all volume levels, but the existence or non-existence of reflections resulting in gain would not be the same, yeah?

I understand the psychoacoustics and that it's a measured fact. I was referring to the comments on AVS Forum being subjective observations rather than objective measurements.

Regardless, I listen to movies at reference level when the sound matters, which is why Dynamic EQ doesn't seem to be for me.
