It shouldn't be any kind of a problem on and even half-decent audio
system (which should have appropriate filters built in). The worst That
could happen is that extreme LF at high amplitude just might tend to
overload input stages, which won't sound very nice. I've heard the
effect described as bugling under water!

Wow! Just looked at it in Audacity - it's pretty extreme! Still
shouldn't be a problem though.
