It's clear that music is a complexed signal that has over and under tones.
Rumble or subsonic waves of a large amplitude are not safe for the listener and can cause heart problem if not collapsing and should be voided.
I've always thought that it's part of RIAA standards to have subsonic filters as a matter of fact since becides EMI causing rumble there are record or pressing imperfections that also can take part especially if played at the high volumes.
