Woofer motion problem.

Whenever I hook up a turntable to my rig, or play a flac file that has been recorded from an analog rig, my woofers flutter in and out dramatically more than with even the most intense digital music. I believe this is like flutter and wow that is extremely low frequencies but not sure. I notice these movements during some of the quieter passages on the LPs. Can anyone explain this and tell me whether it can be prevented?

It was perceptive of you to notice that! It sounds like the compliance of your cartridge, and the effective mass of your tonearm, are not optimally matched, resulting in the combination having a resonant frequency in the "warp region" of typical records (a few Hertz). The following writeup provides a good explanation:
