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.

Football, fast cars, big tits, curvy ass babes, big stereos, "hard' rocking bass

This is what this all about. I dont care what anyone says, Its a little of showing off to ourselves more than anyone. Sure its an awesome hobby but I dont care how into SET amps you are we all look at the Mcintosh gear with the green lights and go thats purty. I personally like big black "ugly" boxes that I think are beautiful, Luckily I have still been able to keep "Curvy ass babes with big tits" around, they always want to change everything when they move in but I always stand my ground, never mind I once settled on a Pathos integrated, She wanted me to get the 3 watt shangling CD Reciever and use it by itself WITH 3 WATTS!!! I guess I won and lost that battle (She eventually moved out)

As far as the lowest octave, Cmon general question for all of you.

How many of you actually got into this in the beginning the very begining. You didnt hear airy and transparent highs and glorious midrange that got you in when you were a kid. It was the bass right. Playing your music LOUD rocking out.

Who can say they honestly didnt go wow, a speaker can do that, no freakin way!!!
I just want to emulate my first car system that had 2 12's in a tiny saturn, Later a competition 15" sub where it sounds good (I thought it sounded good back then)
Er, what I meant to post was;"Some rooms just can'T accomodate low bass, ...."
I really can't hear the lowest notes of an organ recording, but I sure as hell can feel them in my stomach. That makes it real.
