Hell, my old Cornwalls
could reproduce 20 hz pretty handily, even though it was only rated to
something like 36 hz. I know because I could hear a 20 hz test tone.

Probably mostly doubling and/or tripling. You heard *something*, but was it
20 Hz, or was it one or more harmonics? Tell us about your measurement
mics, Weil. Tell us about your analytical equipment.

Why do *I* suddenly have to provide details but you don't?

I'm guessing that maybe what *you're* hearing might very well be what
you're talking about here.

Of course, you really had to struggle to hear it when it was on its
own (I don't remember how many dB it was down, but it was down
considerably - still it was audible).

Remember the Fletcher-Munson curves.

Ahhhh, suddenly you're a fan of the F-M curves. That's funny!

The point I'm trying to make with Arnold, and I suspect that he's
going to play some serious "debating trade" games as usual, is that he
has to prove that the removal of a 6 hz component would be reliably
detectable in a dbt of musical programming, and he hasn't shown any
evidence of that.

That would be posturing. As long as there is musical programming like the
1812, it's a slam dunk.

Prove it. You need a dbt to prove it, right?

I'd also have to wonder if a system that could probably reproduce 6 hz
pretty handily, like Nousaine or the Devil's system could show such
reliability.

Devil's system is imaginary, Nousaine's is real.

It's not real to me.

You can claim that Graham's system is fake all you want. It's just
posturing on your part.

Nousaine's would take Devil's imaginary system to the cleaners, no sweat. That the Devel even
brags about what he has shows how limited even his wildest imagings are.

I don't know who "the Devel" is. Needless to say, you have no way of
proving what Tom's system will do vis a vis Graham's.

Or maybe those guys are falling back on the ole
subjective "But I can hear the difference".

Wrong. The proper statement when it comes to infrasonics is: "I can perceive
the difference".

Prove it by doing a verifiable dbt.

That would be cool with me - they just have to admit it.

Obviously Weil, you've never really been around when a large system does its
stuff.

Hmmmmm, I guess that 3rd row Grateful Dead show last year was just
like hearing a boombox, especially during the infrasonic-drenched
Mickey hart drum solo.

BTW, when was the last time you heard a loud concert? Mine was just
this last weekend...four sets worth...
