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.

The logic involved in intentionally limiting frequency extension is similar to the logic which would say it's advantageous to limit one's visual field. Perhaps glasses should have a black strip at at the bottom to block vision looking through the lowest portion of the glasses? Big advantage, right? That's what is being done with speakers which limit the frequency response. Big advantage, eh?

Someone intentionally wants a truncated representation of something? Fine, good for you. Not me; I'll take the full experience. As long as finances and space permit there's going to be a true full range reference speaker in my home.

Listening levels are not dictated by frequency extension. If you have ever heard a solo vocal piece played with and without a subwoofer you know immediately what LF adds to a system's performance, including clues to the spatial nature of the recording venue. It's misinformation to suggest that persons pursuing LF are just doing so to get the gut punch.

I believe I am not alone in that I care not terribly much the degree of shake/rattle/boom my system has. Instead, I want supreme quality of two channel in all music genres without unnecessary limitations. In terms of pursuing the best sound attainable, when a rig has little bass extension beyond 40Hz it's been seriously compromised.
