The gray curves on the bottom are raw data form different positions and none of them have much deep bass. The top is averaged and compensated with the independent of direction HRTF. He tests them for a good seal by watching the 30Hz square waves while positioning them on the dummy head.
I never got anything near that low with my pair. The level of the bass before it falls off a cliff is fine and you don't always need tons of extension but I had lots of tracks that were nearly missing their drums and bass guitars when played through the SA5000. It didn't react well when I tried to EQ up the bass below about 80Hz or so where it starts to roll off. Though open dynamics never get ruler straight to DC like planars can there are plenty of other open dynamics without such a steep roll off.
I really did like the rest of the sound though...
i don't know what to say honestly then. maybe i'm getting just harmonics then? i tested in audacity with tone generator and it actually reached down to 20hz fine for me rumbling. must be harmonics i guess. i can't say for sure. do you still own a SA5000?
