Who makes the lowest distortion speaker drivers

With a reference point, I would have a much better chance of making the right choices.

It's called "taking measurements" and yes the correlation between many measurements and the perception of large groups of people has been done - see Toole. I have a few arguments with his conclusions (small ones) but for the most part I completely concur with his findings.
 
But there were quite some mixed results in these tests, with lots of people choosing something that I thought was pretty unlistenable.

I once discovered that a "bad sound" that I was hearing on a particular recording was clipping of the source. I developed a technique to remove the clipping and it sounded better to me. I sent the two samples out to many people and for the most part people preferred the clipped one. - Go figure.
 
maybe i'm just a deluded optimist thinking there are some universal truths that can be found and applied.
it's confounding... does personal preference trump general consensus?

Having universal truths does not mean that people will accept them. No one wants to be told that the general consensus trumps their personal perception. But if your personal perception is well out of the norm than you also shouldn't expect anyone to listen to your opinion.

FYI - hearing loss very seldom has dips and/or peaks, > 90% of loss is a gradual declining HF loss that tends to go away at higher SPLs.
 
It was car audio - it emulated the poor sound of a typical car radio of the day.

Another factor in favor of the NS10’s widespread adoption was that it was inexpensive and readily available. For every professional who had a pair on hand as a sort of mid-fi reference, there was dozens of home recording enthusiasts for whom it became a sort of totem. Buy a pair and your mixes will grow three more inches overnight.

Interesting short paper on the NS-10: https://dt7v1i9vyp3mf.cloudfront.net/assetlibrary/n/ns10m.pdf?Mox1MHrRfMC0jrcxfvOtE1aJ4mEwV4P.
From the investigations presented, and from experiences in the use of the NS10M, it would appear that the following statements can be made.

The free-field frequency response of the NS10M gives rise to a response in typical use which has been recognised by many recording personnel as being what they need for pop / rock music mixing. The principal characteristics are the raised mid-range, the gentle top-end roll- off, and the very fast low-frequency decay; the latter is aided by the 12dB / octave roll-off of the sealed-box cabinet.

The time response exhibits a better than average step function response, which implies good reproduction of transients. Many people speak of the "rock and roll punch" of the NS10M.

The distortion characteristics are also better than average for a loudspeaker of such size.

The output SPL is adequate for close-field studio monitoring with adequate reliability.

In many of these characteristics, the NS10M mimics the response of many good larger monitor systems in well-controlled rooms. They are hence recognisable to many recording personnel in terms of their overall response.

They are tools to achieve a well-balanced mix. It is notable how many of the people who use them in studios do not use them for home listening.
 
Scottjoplin is right the thread has morphed into a discussion of design philosophy/approach/
data gathering rather than whether or not driver distortion matters.

seems like the majority would rather quibble and argue fine points and philosophy/religion rather then come to a consensus as to what is truly relevant and how it constructs the bigger picture.

does low driver distortion matter?

It wasn’t even about if it mattered, it was about “who makes the lowest distortion drivers”.

A few of us showed examples but fewer even cared. Oh well.

It matters to me. I have them and love them.

i think your mistaking me for lbstyling on this one Doc.

and as to my perception and opinion being out of the norm and not being worth being listened to...that's a personal bias on your part.

I don't think that this is true. Your link is a "recommendation" - there are no "standards" for studio work and the ones that I have witnessed were not done at 85 dB. I was in a studio recently where the band was playing at > 100 dB and being recorded. The mixing room was not quite that loud, but certainly > 85 dB.

this one is expressing a lot of biased opinion that should be backed up with measurements, no?
did you measure the control room spl or just guesstimate?

That comment was not for you, but for people in general, who often have misconceptions of hearing loss.

And I did not mean your last concern to you in particulate either. IF you find yourself "out of the norm", then ... Maybe your within the norm, I don't know. According to Toole's results I am certainly within the "norm" as I agree with 90% of what he claims the "norm" want. The "norm" here being, from HIS results about 90% of people. There are a few aspects of audio that I don't think Toole has studied in much depth. Nonlinear distortion is one of them. "Imaging" is another.
 
Wesayso - correct, and if lbstyling grants us , oh say $100,000 we'll get started on the project right away!

And the room absolutely has to be a part of the evaluation since how a loudspeaker interfaces with the room is not a small factor.

I think have some pocket change here somewhere.....

I'm sure anything you don't know about room interaction Earl, isn't worth knowing. But you cannot have an apples with apples comparison if you include it. That's not to say that you cannot also have tests that include room interaction, just that it would be unlikely to be considered empirically comparable between users under any constraints you would accept, no?

I'm suggesting it would be useful for designers to have a $200-$300 reference point speaker to compare notes with when making measurement or anecdotal comments about new designs. Its all just a bit of fun people!

I'll say it again, a reference point, not an ultimate reference level speaker. I would suggest we could take the discussions of the drivers discussed on this thread as information to support a shortlist. I hear good things about the Satori driver measurements.
 
If you have noise induced hearing loss you will suffer a dip, I don't know how common this is

Depends on the type of noise. Wide-band traffic noise for example will not have notches, but the impulse from shooting a gun will always arrive at the same time and is by far the worst culprit of "notch" loss. How common is that? I don't know, most people that I know use protection. I do now, but didn't a long time ago. My hearing has a little greater than average loss.
 
I spoke to a lady who used to conduct hearing tests for the NHS in the UK, she said 'heavy users of motor cycles and Power tools' always had a dip.' I assume this was based on her experience rather than formal test data.

Be careful with definitions. A "dip" is common, a "notch" is not. To an audiologist a "dip" could be several octaves wide, so a Q of .5? Let's agree on a "dip" as Q < 1 and a notch Q > 1. "Notches" would be rare. "Dips" quite common.
 
As discussed earlier and in detail in this thread, EQ can be used to flatten the FR of drivers due to resonances and hence reduce distortion.

EQ is used to compensate for room response to a degree, does this reduce room distortion, does it have a negative effect on speaker distortion or do we have to balance the pros and cons?

Then there is EQ for personal preference, I presume this should be used in moderation to avoid significant distortion?

While you're here Earl, any thoughts on the above? :)
 
If you mean linear distortion, of course, however, EQ would have no effect on nonlinear distortion.

"room distortion" does not really have a definition in my lexicon. Rooms have complicated "frequency response" differing across the band in many ways. In the modal region EQ could smooth the linear response, but again, it would have no effect on the nonlinear distortion.

"EQ" for "personal preference"? No Thanks.
 
That is a very complex question.

What one wants is for the direct sound, the sound before any room reflections, to be smooth (near flat, but slight HF downward slope) AND, and this is a big and, the room response to be smooth as well. If the speaker is designed to be flat by the manufacturer, and is so when it ships, then no room EQ is going to improve that speaker. It can only degrade it unless the original speaker design was flawed in some way.

In the modal region, things are the exact opposite. The free field response matters not at all and the rooms modal region EQ is essential and dominate.
