Subsonic frequencies are often recorded as low frequency effects in
some DVD movies. Watch "Das Boat" on a home theater system equipped
with an 18" Velodyne subwoofer and you will be convinced. Nothing you
hear, but certainly something you feel.



Das Boot isn't a music CD, which is the topic or our conversation, right?

There was theme music in "Das Boat". :-)

However, I still disagree with your statement,

"You also don't need a $1200 woofer that can reproduce 10-50 Hz, because
the only thing
down there is turntable rumble and a few heavy trucks rattling FM detector's
tuned circuits, in older radios."

My feeling (and experience) is that a good sub that can produce subsonic
frequencies sounds much more natural and tight when using it to reproduce
the low bass frequencies of an acoustic or electric bass, especially with
digital recordings.

BTW, $1200 for a good, powered subwoofer is a steal.
