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.

Electronica artists have the freedom to create music without the limitations of traditional instruments. They can be creative in any octave they want and I don't want to miss out. That's why I have a pair of JL subs. I saw Crystal Method live in Santa Cruz at an older venue and I really thought the ceiling might start to crack and fall on our heads due to the extreme bass. The room seemed to be shaking vertically even when the volume was low at times. It may have been "unnatural" but it was their art and creation and we were having a blast. Don' wanna miss out on that in my living room!
To ignore the range from 20 to 40 Hz is to deny the FACT that there are harmonics down in that range that do affect realistic music reproduction. Not to mention that there are also ques down there that give us the impression of a large hall for example.

Don't believe? Listen to a cello on speakers that cutoff at 40, and then listen on a full range pair. Many people do live with the lowest octave, and many live without much above 12kHz, but this does not prove there is no valuable information there.

Elizbeth,

I usually find your posts to be very informative, but I have to say that your passing this off as some testosterone-laced fantasy is beneath your knowledge. Maybe you just meant to poke fun at us guys. ;-)
If one can get deeper bass without any tradeoff of other qualities, why not? But, such "free" deep bass is hardly ever achieved. Bigger drivers able to push more air usually means more mass (inertia makes such drivers less nimble), bigger cabinets (hard to control resonance), and most significantly, deep bass response usually means much lower speaker efficiency and the need for higher powered amps. To me, there are very few higher power amps that deliver the kind of performance of low powered tube or solid state amps.

I care less about high volume, extremely deep bass than I do about good behavior where most of the music resides in the lower range. I want realistic tonality to bass. There are a lot of speakers on the market with extremely tight, punchy bass, that lack the ability to deliver the proper tone and harmonic structure of lower range instruments (double bass, kettle drums, contrabassoon).
Reaching down to the lowest octave creates a realism in music not otherwise experienced. Even though the fundamental note may only go down to 40Hz there are overtones reaching far below giving music the proper foundation.

It's not a guy thing and it has nothing to do with balls. Men have larger eardrums than women giving them the ability to hear low frequencies better than women.
Its human nature's hard wiring of the brain. Think about it, the fight or flight instincts of the human brain are more influenced by hearing low octave sounds. When you hear the rumble, T-Rex may be near, and that is exciting, know?
Great post, Mitch4t.

I've heard it said that a lot of the information that communicates the size a recording venue comes from the very deepest bass.

Yeah, I'm going with what Tvad said.

I have a set of Infinity IRS Betas. According to the spec sheet they go down to 15 hz. Every year around the first of the year for the past three years I've put them up for sale, this year is no different. Every year around July or August I get sick and tired of them taking up so much room in my living room (they are 4-chassis speakers with a total of eight 12 inch woofers in two bass towers five and a half feet tall). So I put them in storage and trot out my Infinity Kappa 9. The Kappa 9 have great bass with two 12 inch woofers per speaker and they go down to 29 hz. I am thoroughly satisfied with the bass of the Kappa 9. When potential buyers call me for an audition of the Betas, I have to bring them out and set them up for an audition. Once I get them set up and start playing music, I think to myself, DAMN, that is some serious bass and wind up keeping the speakers and not selling them. There is something down there below in the lower 15 hz that the Kappa 9 cannot reach and you can feel it immediately with the first song and know that you have been missing it immediately. It is an incredible experience. So, I wind up not giving a damn if they sell or not, or taking them off the market altogether and setting them up again to take up too much space in my living room until I want my living room back. So yes, there is a LOT to be gained by stretching the bass performance below 34-40 hz. When you get the opportunity, go down where the Lords Of The Low Frequencies reside at 15-30 hz and experience it....there's nothing like it.

This word was one of the few contributions to our culture by Warren G. Harding if I remember correctly. At least he was the one that popularized it.
Lithojoe - Seeing the word "bloviate" reminded me of the excellent comic series:

Non Sequitur Political Zoology Field Guide

http://lawwreview.blogspot.com/2010/12/political-zoology-field-guide-tone-deaf.html

I think this link will get you to the bloviate one, but there is an entire series if you do a little looking, it's worth your time.
My main speakers don't go low enough, but sometimes I do turn a sub on just to catch that natural distortion you refer to, that happens in a large auditorium. And its all part of the natural non-amplified music experience.
Feel me and he nailed it , sounds like more of his distortions! I went to a Blue Man concert and I sure could feel it in mid hall or balcony. Let's just bloviate with more of the idle chatter, which smells to the high heavens.

Feel me ?
Most people here who are listening to deep bass are actually listening to mostly distortion - although manufacturers won't admit it - sad to say but distortion sells really well
You do catch a lot of low bass in a large building/auditorium. It does help make a life like performance at home. There is information down there that are caught of the right recordings.
Tvad nailed it like he often does.
If its meant to be there and the folks who composed or wrote the music went to the trouble of putting it there why not strive to hear their efforts?
Doesnt seem weird or silly to want an honest and full scale reproduction of it to me.
Hearing that air, extension or feeling that impact is a big part of the wow factor, clipping off the bottom end just IMO goes against what we stand for, honest reproduction.......if it aint there then how honest is it?

My Focal 836v speakers are rated for 40Hz to 28kHz +/- 3dB with the low frequency cut off at 33Hz. I have a test tone CD and verified that they would produce an audible tone at 28Hz with my Integra receiver, but would only do 30Hz with my Onkyo. Having them up against the wall provides bass supported (some might call it bloated), but it works for me the majority of the time. The subwoofer stays off for most critical listening.

Even though my speakers are said to go to 30hz, I have often wondered whether cutting them off a little higher and blending in a pair of quality subs would result in not only deeper bass but better defined bass. OTOH, some say it is exceptionally difficult to accurately blend subs and maintain coherent phase. Yes, I like well defined, textured, deep, punchy bass, but can live with slightly rolled highs, as long as they are smooth, brassy when necessary, but never tizzy, grainy or shrill.
My speakers go below zero down to -10Hz thanks to the quad of 36" woooooooofers.

The bass is so low that you can't hear or feel it.

But I know it's there because the Stereophile measurements don't lie.
Well, in defense of my sex I can say that women only like that "sissy" music
that has "no balls". If we are done now with stereotyping, perhaps we can return to discussing stereo equipment.
Often one will chose to not worry about it initially then tackle it later once all the rest sounds right.

True that most can detect the lowest normally audible frequencies but not the highest as ears age.
From a different perspective. Talking about treble say from 15k to 20+khz is difficult. No matter how high you turn up those frequencies you can't feel them as you can with 20 to 60 hertz bass. Also many people can't hear them, which is why there are reports every now and then of teen age girls using 16khz or higher tones for their phones. They can hear them ring but the teachers can't. So it makes more sense to talk about something you can hear and feel than about something you may not be able to do either or both.
Because part of the music occurs there normally with a good recording or live and this is the " high end" audio site where everything that you can or should be able to hear matters.

Having said that, it does not in practice really matter to many.

I could live without it if I had to but prefer to not.

Elizabeth is probably on to something with the "guy thing" assessment.

The 1036 is a bigger and more expensive speaker. The 3 db down point on the Electra 1037 BE is 33Hz in its test in HIFI+ issue 52. As it has 3 8" woofers rather than the 2 of the 936 [ according to Audiogon Blue Book] and costs roughly twice as much it is hard to see how the 936 could have better bass. When we say that a speaker has response to a given frequency we mean that it has a flat response to it; my REL subs produce audible output at 15.5 Hz but I don't regard them as going that low. To get a speaker that is only 3 db down at 28 Hz takes either size of money or both. The Wilson Sofia 3 just manages 3.5 db down at 28 Hz and it is an exceptional performer in the bass.
Mine goes to eleven!

I'd agree that quality of bass, and control as well as balance, is all very important. Just because a speaker can reproduce down to XXhz does not mean that it does a convincing job in portraying those lower frequencies and the instruments that produced them. I think this is one of those things that reveal the limitations of graphs/numbers/measurements in telling the whole story. Here's where having two ears comes in mighty handy, and gives you a better idea of what the speaker in question is capable of. As far as why such a stress is put on it, one need only take a listen to a system that really gets that right can bring to the table, in order to understand why it is so coveted in spite of the fact that the majority of what we listen to exists on the middle rather than the extremes. It brings in one of our others senses big time (touch/feeling) and connects with us in an almost primordial way. I think it is also VERY difficult for a speaker/system/room to do well, so when that is done well, it's pretty amazing to experience.

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.
Mechans - Quality of the bass is more important than extension IMHO. My current speakers have larger drivers and more volume than my old speakers but extension is slightly worse. Dynamics, attack and decay of the bass, on the other hand, are much better. It has to do with tuning for the lowest distortion and not for the extension. Of course it is the best to have both but it also costs both - an arm and a leg.
My tweeter goes out to 60,000 Hz [I'll take their word for it] and there is no music out there either. Good subs make a difference even when there is no music supposedly below the range of the main speakers; once you hear it you will miss it when it is gone. I sometimes forget to switch on my subs; I don't notice it right away but gradually realize something is missing. An actual 28 Hz speaker is a rare bird indeed, I don't think the JM 1036 really goes that low if I remember the HIFI + test.
The same could be said for the highest octave. As for me, I disagree. Yes, I know most music (about 80%), is in the midrange, but I want it all, and miss it when it's gone. I suggest getting as much of the music that's on the recording as your budget and room permit.
