World's best midrange Blind Testing - Need your help.

Just made an update on page 1.

Thank you to all contributors in my quest for the best midrange drivers.
Got many interesting suggestions and i sure will consider some of them.
Since this thread as drifted to more noise than signal not too long after his beginning, i'll now communicate essentially by private messages; so if you want to get updates on the test, video link, photos, data, etc... you'll need to send me a PM. Thank you and good luck in your future projects!

🙂
 
Sounds like a statement describing many here throwing out so called objective arguments … many of those as yet unsubstantiated as valid indicators of ear/brain response because there have been few scientific experiments coorelating the "objective" measures with what the ear/brain perceives … as such those people have made a subjective choice that the objective measures are valid.

One of the most intelligent and pertinent message i read since i'm on this website.

Remember that science is a bunch of theories not yet proven wrong.
Nothing more, nothing less.

And, more importantly, there is a real danger to use some parts of the science only to prove our points or opinion. That is normal, it's very human.

But a real scientist approach is to remain open-minded to the parts of science... that might end proving us wrong.

So, let's start with that, shall we ?

That is strange to not post the final video links and data in the thread body but to keep it private. I agree the thread has drifted off - so it's ok not to respond if you don't want. But to hide the results to come under PM's?

Already answered that:

That might weed out people who just stays for the entertainment, the drama and all the sh_t.

People who are genuinely interested will contact me.

Others, well, they'll have to find another entertainment.

(anyway, the very purpose of this thread is pretty much fulfilled, isn't it ? Not much driver's suggestions in the last... 30 pages...?)

Mission accomplished. Now let's do the real-life action.
 
https://en.wikipedia.org/wiki/Psychoacoustics

Hearing is not a purely mechanical phenomenon of wave propagation, but is also a sensory and perceptual event; in other words, when a person hears something, that something arrives at the ear as a mechanical sound wave traveling through the air, but within the ear it is transformed into neural action potentials. These nerve pulses then travel to the brain where they are perceived. Hence, in many problems in acoustics, such as for audio processing, it is advantageous to take into account not just the mechanics of the environment, but also the fact that both the ear and the brain are involved in a person’s listening experience.


That page (and other similar content) should be mass-printed and sent to all audiophiles on the planet. Twice a week.
 
Churcher and King carried out a second determination in 1937, but their results and Fletcher and Munson's showed considerable discrepancies over parts of the auditory diagram.[1]

In 1956 Robinson and Dadson produced a new experimental determination that they believed was more accurate. It became the basis for a standard (ISO 226) that was considered definitive until 2003, when ISO revised the standard on the basis of recent assessments by research groups worldwide.

... and yet, see attachement 😉

So, no definitive answer at all, even less a universal answer (that applies to every single human being with better accuracy than some loose approximation).

Talk about some nasty variable.

Indeed it is a semantic thing and you are mixing two ways of naming the same thing.


Frequency Order Name 1 Name 2 Name 3
1 · f = 440 Hz n = 1 fundamental tone 1st harmonic 1st partial
2 · f = 880 Hz n = 2 1st overtone 2nd harmonic 2nd partial
3 · f = 1320 Hz n = 3 2nd overtone 3rd harmonic 3rd partial
4 · f = 1760 Hz n = 4 3rd overtone 4th harmonic 4th partial
(from wiki)

Sorry it got a bit squished pasting it and is resisting all my attempts to fix it but it should be possible to figure out what goes with what.

Either way the reason nobody talks about 1st harmonic distortion is because there is no such thing, the 1st harmonic is your input signal or 'fundamental'.

Hi!

This will be my last post on this side track not to pollute the thread more. I think most people get it. Please PM me if you wish to discuss this further.

I do not mix anything up and I mean just what I wrote. I did not suggest "1st harmonic distortion" as you imply. I only said that there is a first distortion product above the input stimuli/ fundamental tone, which typically is a 2nd order component or a 3rd. When I explain this to a novice I explain that we have this input signal and out comes the same tone with some crap added. The first spectral component... the first harmonic distortion product is what is called a 2nd order harmonic distortion component since it has a mathematical relationship of 2 with the input. It's the first guy poking up above the gras in an FFT that is not the input component.

Now try to understand what I write instead of saying I'm wrong or mixing things up, I'm not. 🙂
 
VERY disappointed to see the dogmatic technologists hound yet another interesting contributor off the forum. This gets poorer by the day.

Hounded? All the technologists have done is calmly and objectively defend their positions. While JonBocani has been condescending, dismissive and downright insulting at times towards the objectivist position, yet this is supposed to be acceptable?

DIY Audio is primarily a place of learning and sharing of ideas (where do you think I learnt a lot of what I know?). One needs to come with and open mind and be willing to engage with people right across the board in terms of education level, experience and with people that hold different points of view.

You cannot dismiss people as you see fit because either you do not understand what they are talking about or because their point of view doesn't fit with yours.

I have no problem with subjective opinions and points of view, there is a time and place for them however, just how there is a time and place for integrating the objective into your design process. You do however need to know when and where to use both otherwise you're not going to get very far. All the objectivists have done here is try and point that out. Things have then become more heavy handed when JonBocani simply chooses to ignore the advice that he needs to take into consideration, otherwise the subjective point of his testing would be largely irrelevant. Fun maybe, but pointless towards the end goal of actually selecting the best midrange for the job.
 
I guess this is what happens when we're too hard on ourselves, and it inadvertently carries over to how we interact with others. How a person confronts others may be a reflection of how he or she confronts themselves. Sometimes I speak before I think. I think it's a natural survival based instinct reaction. Then my frontal cortex kicks in, and I might realize that I should have thought more before spewing. Sometimes the same intense determination that makes an engineer great, also makes him abrasive and even corrosive to others. I tell myself that balance is critical. Go camping in the mountains, play guitar, work hard and party hard, but intelligently. Be open to being wrong, and have a sense of humor about it.
 
Its Jons thread....

Guys,

I think the same rules should apply to all....

This is Jons thread and he has the democratic right to conduct whatever tests he likes in whatever way he likes....He asked for some help in compiling a list of drivers....He received a good selection and has thanked us for our suggestions.

Now a few of the "usual suspects", the so called "heavy hitters" who are only big fish within the tiny (and diminishing) pond of DIY loudspeakers....Have indeed hounded Jon to the point that he is withdrawing from further public sharing.....

You established members should be ashamed of yourselves....
Just because Jon is obviously successful and is able to put significant resource into his audio projects he has been hounded by a small group of obviously less well heeled closed minded individuals….. Jealous or what....?

The closed minded attitude displayed by those who claim to be open minded is shameful…
“If you don’t do it our way its no good”….You one horse town guys are absolutely the single biggest downside to this otherwise excellent forum.

If I was in charge of this forum heads would roll….Dustin I urge you to read this thread and think about how Jon has been treated.

Derek.

PS I have no connection with Jon, in fact he has dismissed my advice totally, which is his choice, take it or leave it…This post is not about the technical aspects of Jons post, its about the attitude of existing members towards a new member.😡

In real life, we read each others tone of voice and facial expressions as much as the meaning of the words that are expressed. In e-mail or any kind of internet forum, we lose that important tone of voice and facial expression info. It's easy to misunderstand what's been said, and take it much more personally than it was meant.


In Facebook, you can "un-follow" a "friend" that never knows when to stop pointing out what's wrong with life 25 times a day, without actually "unfriending" them. Maybe this site could have something like that. The angry person could still rant, rave, opinionate, brag, condemn and make a fool of himself, but any others in the thread could turn off his entries permanently, without him even knowing it.
