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.

From Wikipedia:

"A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation."

So if it is in the source but not heard, it is an alteration and can be considered a form (by omission) of distortion.

How acceptable is it in those terms now, audiophiles?

This is truly how I look at it personally and why I find I cannot be satisfied fully (despite being satisfied greatly still though in practice ) by even excellent smaller speakers otherwise that punt by design and chose to omit the lowest octaves in order to achieve greatness.

"Imagine the impact of the tympani had you been sitting closer."

I can only imagine, but I would propose that it is possible the impact could be less sitting closer if sitting on a more rigid floor or foundation. Its possible that being higher up and further away yet in an elevated balcony transmitted some of that bass energy through the structure, ie "the place was literally rocking" maybe.

Also, the balcony was elevated with the tympani in direct line of sight so I suspect it took a direct hit from the soundwaves, whereas the floor is closer but below the stage, so the sound waves transmitted might be lesser as well.

YEs, Tvad, we audio kooks are an anal bunch indeed....

I will never forget the visceral sound of that particualr tympani in that particular setting though. It was almost an "out of body" experience that seemed to defy physics. I was left disoriented for a moment and trying to figure out how what I just heard actually happened?

ISn't that the kind of thrills we misguided audio head cases seek,afterall?

"My idea of really bad low frequency is driving, then hearing some morons' thumping crap subs from five cars away at a stoplight, and being stuck till' the light turns green. "

Yes, I agree. That IS the worst!!!!

Some of the things I have heard in Best Buy and other stores that target the masses are close behind.

I used to sell car stereos at Radio Shack years ago. I am proud to say I managed to always resist the urge to sell car stereos and make commissions by cranking up distorted bass. I did OK though despite by just trying to keep focused on quality, not quantity.
