  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.

Why the obsession? Everything discussed in this forum is about obsession.

I like deep, but not too deep bass. In fact I like to have a upward tilt in frequency response below 40Hz. It sounds good to me. But what I have discovered from looking at countless spectrograms of popular music recordings is that there really isn't that much information below about 40-60Hz. As long as the harmonics are present, the ear/brain fills in the "missing" fundamental. However, if the recording actually has true low frequency content, then I like to hear it.

My system goes down to 25Hz and then steeply drops off. Are some people saying that there's musical info below 20Hz?

One last point, humans had not evolved when dinosaurs existed. Human hearing is not at all sensitive to low frequencies, witness the Fletcher-Munson curves. Humans are most sensitive to upper midrange sounds. Think about it.
