I believe their testing was flawed.
Sound waves have a wave length. The lower the frequency (the lower the pitch), the longer the wave. The problem is that if you are within the first soundwave, you won't actually hear it.
I believe it is that one of the lowest sounds that the human can hear has a soundwave length of 17 feet. If you're within 17 feet, you won't actually hear the sound. This is why subwoofers exist, to give you the feel that you are actually hearing the low frequencies, even if you're right next to the speakers.
Anyway, when they went really low frequencies, they placed the red head right next to the speaker, way within the wave lengths.
Therefor, I think they did the testing wrong.
