Guy,
When I listened to the second clip using headphones, I didn't hear any
significant distortion. But when I played it back using the cheap
speakers on my computer, I got significant distortion. I think
something in the speakers is resonating with the lower frequencies in
the rumble.
As someone else pointed out, most of the energy (at the point of
distortion) is at 60 hZ and below. The subsonic components could easily
cause resonances in a speaker. The first clip doesn't have nearly as
much energy in the subsonic range.
I didn't hear anything that sounded like digital distortion or clipping.
