Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

@kota1 

@amir_asr , the title of this thread is not cables anything. The title is about manufacturers and measurements right? I posted the specs of the cables I list in my virtual system because it got right to the point of the OP, that’s it.

This is the title of the thread:

Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

Before I showed up on page one, you all started to talk about cables.  Hence my questions to you.  You have not posted anything about the cables you say you fell in love with.

Nothing in the thread title is about in-room measurements of people. Nor are the members here showing any interest in such measurements.  As I said, create a new thread and see if there is interest in it.  If there is, and you have something worthwhile to say that is not just noise like these posts, then I will engage.  Until then, we are discussing manufacturers and why they don't post measurements.

As for @mikelavigne he was nice enough to contribute to a thread I started about end game systems. That thread wasn’t about measurements OK?

You post it here in the context of measurements.  And your demands that I show in-room measurements of mine.  You showed no interest in his room measurements so clearly letting your eyes judge his system.  As such, you are a prime target for marketing department of audio companies.  They love non-critical people who go by looks than objective performance or controlled subjective listening.

That is true but not in the manner you are thinking. Gated measurements are used in Klippel for higher frequencies (usually above 1 kHz -- it is a user setting). Lower are generated using field separation giving you very high resolution down to 20 Hz (or even lower) -- something any reasonable sized anechoic chamber can’t do

1. The FR was shown through the research to comport with listener preference.
   1. In a bare 2 channel set up without any DSP (As in pure, or bare, or whatever we want to call it)… then FR is important.
   2. In a DSP system, FR loses importance.
2. Directivity preference varies, but the content of the in and off axis is important to the preference of liking it.
3. The actual time domain “polarity” was deemed to be not strongly statistically important. But some people seem to notice it.
4. As we know the waterfall shows the FR as well as cabinet ringing.
5. Then the distortion seems to be tolerated in low frequencies and in terms of HD, but not very tolerated with FM and IMD.
   1. Many people do not seem to care about driver distortions and linearity.

I’ll admit I like #3, and I like low distortion drivers (#5).
I cannot imagine a preference for high cabinet ringing and high distortion… but if the O/96 speakers are that, then I can see why people like them.

We may have a problem with the wrong measurements, or with maybe the frequency not extending as low as we would like… but IMO it is more of a problem that most speakers have no measurements. And also all the boutique power cords, IC, and speaker cables have no measurements or specs.

The ones that do have measurements are generally pretty well liked stuff, Mogami, Cardis and other bales and ICs. And Genelec, Dutch-n-Dutch, Bouchard, etc.

However; this thread either started off as an attack on specs, measurements, ASR, or you… it could have been some spreadsheet of what have measurements, and how well the gear is liked to see if there are any correlations… But alas, it is not that.

well… you and I are sticking to the “manufacturers and why they don’t post measurements”.
 

I am not a shill for any company. 

^Agree^, I just did not want it perceived as being a shill.

Companies don't need anechoic chambers.  They can simply rent space in one or get Klippel to measure it for them.  The cost is less than $2,000 for a speaker.  If a company can't afford to do this, or can't be bothered, it is not going to get my support.  It is one thing for a DIY to not afford such fees, it is entirely different matter for a major company.

That is true for R&D maybe. But they might need some chamber or way to maintain QA.

Note also that we are not not just looking for a few simple measurements.  We want full CEA-2034 plus distortion measurements.  A few gated measurements are not going to do it.

Agree.

Thanks coach. Do you hold classes on this everyday or every other?

My dog is a big believer in yoga by the way

I imagine canine Majidimehr is a more capable student than human Majidimehr. And better at dog pose. But I notice you practice the twist poses frequently. Which is your favourite?

Before I showed up on page one, you all started to talk about cables.

Don’t you mean "you people"?

Now now, I said human Majidimehr. I like to keep it civil.
