How low can one hear Huh?? Say again

Thank you Albert.
Merry Christmas (can I say that?) :~) to you and your family.
Anyone else....this really bugs me.

I can't say for sure why that statement can be made. I've read things on hearing that says youngin's can hear down to 16 Hz and the range of normal hearing is 20 Hz to 18 kHz. I can hear (barely) the 20 Hz test tone on the Stereophile Test CD . Granted, it's not very loud through my speakers but it's still audible. It can also be felt - which is a big part of the musical expression with instruments as double basses and contrabassoons. I cannot agree more - speakers that cleanly go low 'n loud express music better.

If anyone is interested.The review in question is in stereotimes.com
Go to the bottom of the page to the archive link.
The review is of the Xindak FP-1 speaker cable.

sorry..its the Xindak FS-1 speaker cable.
The FP-1 is a power cord.

In order to "hear" 30Hz etc sound, you have to allow for the wave length: ~38'. Usually we FEEL the direct sound of 30Hz and we hear the reflected sound (i.e. somewhat later than it occurs).
As to the reviewer, I couldn't say. 30Hz is not that low, and there's some music content there, sometimes (not much, but still). Apparently, and fortunately, he's never experienced an earthquake. That's lower than 16Hz (a large organ will produce 16Hz).
Generally speaking we DO perceive low bass sounds. They are unpleasant (to me).
