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.

All due respect but I had used a test tone CD which did show that they produces a low note at 28 Hz. Below that the tones made the woofers wobble in a frightening long excursion but made little sound. I will check again but these are the 936 Electra not the 1036.
The big problem I think is the idea that really low bottom octave bass sounds muddy blurred smeared etc. I happen to think it does also. Maybe I get that impression from the wretched super subs installed in that SUV 5 cars away annoying the living S**t out of me.
That being said I am curious to know what it is that I am missing out on, when these low sounds are properly reproduced. I am very curious how Duke's systems work. Yes I too was a bass freak as a kid. I grewout of it quickly and purchased Klipsch Heresys for my first real system in 1976.
At that time people really liked Cerwin Vegas for rock because they had such loud bass. I don't think any of us even knew what a subwoofer was. Maybe they weren't invented except for Bud Fried's "Coffin" system.
The new wave of music that was the thing at that time included Punk which was pretty much a distorted wall of sound played really loud. The Heresys didn't dissapoint.
The specs on my Klipsch clearly showed no bass below I think 50Hz. In real life I think they didn't make much bass below 60Hz unless you put them directly on a non carpeted floor. That's what I did. Later I used them as BookShelves really on shelves.
