Why the obsession with the lowest octave


From what is written in these forums and elsewhere see the following for instance.

Scroll down to the chart showing the even lowest instruments in this example recording rolling off very steeply at 40 Hz.

It would appear that there is really very little to be heard between 20 and 40 Hz. Yet having true "full range" speakers is often the test of a great speaker. Does anyone beside me think that there is little to be gained by stretching the speakers bass performance below 30-40 cycles?
My own speakers make no apologies for going down to only 28 Hz and they are big floor standers JM Lab Electra 936s.

Most people here who are listening to deep bass are actually listening to mostly distortion - although manufacturers won't admit it - sad to say but distortion sells really well
My main speakers don't go low enough, but sometimes I do turn a sub on just to catch that natural distortion you refer to, that happens in a large auditorium. And its all part of the natural non-amplified music experience.
Feel me and he nailed it , sounds like more of his distortions! I went to a Blue Man concert and I sure could feel it in mid hall or balcony. Let's just bloviate with more of the idle chatter, which smells to the high heavens.

Feel me ?
Lithojoe - Seeing the word "bloviate" reminded me of the excellent comic series:

I think this link will get you to the bloviate one, but there is an entire series if you do a little looking, it's worth your time.
This word was one of the few contributions to our culture by Warren G. Harding if I remember correctly. At least he was the one that popularized it.
