Woofers shake uncontrollably at moderate volumes with turntable source; why?

When increasing the amplifier volume beyond a certain level, my speakers' woofers begin to shake spasmodically when my turntable is the source. However, the same problem doesn't occur with a digital source at higher
volumes. What's goin' ahn?

I've witnessed woofers shaking like this before when presented with low frequencies at volumes higher than they can handle, but the digital equivalents of the music I'm playing indicate that the source of the instability is not the audio. My turntable is decoupled by both a vibrapod/acrylic plinth sandwich and a dual plinth/sorbothane design. Suggestions?
