If you look carefully at the top, there's a sneaky s in there. Now you know why REW is freeIn the bass region, the magnitude (coloured) is much lower than the Pinna-region, but decays remains as long. Is that a smoking gun for the other bass drivers making sure that the (total if you like) bass decays 'slow' like a DD? Physicist here, y-units are off (m =/=ms)
I am a research scientist, so I know what you are talking about lol.
