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


After my Audio Science Review review forum, it became apparent that nearly the only way one can determine the measurements of an audio product is wait for a review on line or in a publication.  Most equipment is never reviewed or is given a subjective analysis rather than a measurement oriented review.  One would think that manufacturers used tests and measurements to design and construct their products. 

Manufacturers routinely give the performance characteristics of their products as Specifications.  Those are not test measurements.

I searched the Revel speaker site for measurements of any of their speakers and could not find any.  Revels are universally lauded for their exceptional reviewed measurements.  Lack of published manufacturer measurements is true for nearly every speaker manufacturer I've searched for on line, perhaps several hundred.   Same is true for amps, pre-amps, DACs, transports, turntables, well you get the picture.  Do they have something to hide?   I doubt the good quality products have anything to hide but poor quality products do.  

ASR prides itself in providing "true" measurements that will aid in purchase decisions.   Why don't the manufacturers provide these measurements so that reviewers can test if they are truthful or not?

Then there are the cables and tweaks for which I suspect that there are inadequate tests available to measure sonically perceived differences but which objectivists believe don't exist or are "snake oil."  

Well, please chime in if you have some illuminating thoughts on the subject.   

I would have loved to see manufacturers measurements on my equipment and especially those that I rejected.

@kenjit 

join the ASR forums and post your evidence. We will have a field day with you.

They will just ban me, no one is allowed on that forum unless they kiss your masters.....feet.

Evidence posted, now bring your master to post his ok?

Those measurements are meaningless. What is it supposed to prove? Now show us some polar response plots liked Amir does and we will have a field day with you! I dare you! You will be shocked at the directivity errors!

You have massive room issues going on below 100hz. All you have shown is that you know how to use an EQ. Anybody could use an EQ to get whatever curve they liked. You have proven nothing important. You are wrong.

I said: ASR is powerless to influence the highest ranks of this industry; such as the top-most Studios, wealthy audiophiles, and audio dealers.

Either way, if you write lousy reviews that undermine the actual capabilities of audio equipment, most people might believe it: since they are non-technical. Again, I say that you can't influence the enlightened folks who know their stuff.

I have more speakers than just the TADs. The TSM-300s were really good. TAD or any other company is not afraid of ASR. 

Going up against @kota1 is a very bad idea. Are you nuts?

 

 

@kenjit

That plot also has before EQ, (the red measurement curve) it looks great. The challenge is about measurements, not talking. Still waiting... (you forgot to call me "king of all measurements", next time ok?) for some type of measurable response.

What success? 

A failed tech executive at Microsoft, worked at Sony for a while, made no meaningful contributions that stand today. No one from his generation knows who he is or what he does. He is extremely unpopular on the web and forums in general for a reason. And you know what that is...

Ask Amir to remaster a track. I get to choose. With his butchering of EQ, I can only begin to imagine how much worse his finished product would be...

Post room measurments @amir_asr or...be a man and have a real discussion.  Your friend is far too helpful ....probably because he is you!!
