You can see in the video that a laptop is used as a source not a turntable. Perhaps the cone excursion is due to a port implementation. However, referring to an earlier example I gave, the Audio Physic Caldera, exhibiting the behavior under discussion, was an infinite baffle. I also believe that a passive radiator is considered a variation of a bass reflex port in loudspeaker design.
Of the loudspeakers I have owned, the ADS were both infinite baffles, the PMC used a transmission line, the Avalon a long vertical tube and the Gallo is an infinite baffle. None of these loudspeakers exhibited any perceptible cone excursions. I cannot feel otherwise that such dramatic cone excursions are sources of distortion of varying magnitude.
