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

@kota1, we are in agreement about Amir's room. What a disaster. My ears are ringing just looking at it. I do respect those speakers though. There are some that ascribe to a view that we can adapt our hearing to complex rooms. Probably that is true, but also probably true only to a degree. I think that is an old view that is being rewritten as more become aware of what good room acoustics can do.

On another topic, after reading this thread, and a comment you made I think I can clarify what Amir was saying about your ARC room correction measurements. I don't know why he didn't just say it instead of being confrontational. In your Arc posts, you show the Red measurement curve, the Black target curve, and the Green corrected curve. I think the point Amir was making without saying it, was that the Green corrected curve is a predicted corrected curve. It is not a measured curve post correction. Arc shows you a prediction of what the curve may look like after correction. I think he was implying you thought that was the actual curve post correction, not a predicted curve post correction.

I got sucked into the rabbit hole and read far too much of this topic. I am torn between rolling on the floor laughing at the gymnastics some will do to discredit others, and feeling I need a shower to wash off the filth for the same reason.  I do say @mastering92 , you have quite the sense of humor,

per mastering92: "A failed tech executive at Microsoft"

per bio: "During my time at Microsoft, as VP of Digital Media Division, I grew to manage a division of nearly 1000 engineers, testers, marketing and business development people." 

Hands up all the "failed" executives who have ever had a 1,000 people working under them. But that is getting away from audio. Before I respond, I can say that I personally, for professional reasons, find value in the work that ASR does. I can also say that there are many things about ASR, and more specifically the tone of the posters and the unearned for many of them, air of expertise they exude, that I do not like. I take what they do for what it is worth, predominantly competent measurements (at least for speakers, not all, but most). Attacking the equipment they use is not a great place to start if you want to win an argument. They are using the same, best in class, equipment that the better manufacturers would use.

I can't offer you a professional perspective on the impact of ASR on the high end consumer audio industry (though I will make some comments later), but I can make a comment on the impact of ASR on the professional market, and that is in general education. I am surprised by how many will make comments like "I read about that on ASR". For me, that makes my job easier. What about the consumer market. Well this topic is up to what, 10 pages, most of it an attempt to discredit a website that according to so many "does not matter"? How many more topics just like this would I find here, or posts sprinkled around many topics?  That is a lot of head space for something that does not matter.

@kota1 you must have very long arms. I don't think you will be taking the crown away from Amir any time soon. Big fish, very small pond. No need for the crown for me, I have my own Klippel to play with any time I want. Technically not my own, but close enough.

My post had nothing to do with that though. I was simply pointing out that the green curve is a predicted corrected curve, not the actual measured corrected curve. I am sure as the "king of all measurements" you knew that though.

@mastering92 , how many people work under you?? What is the most number of people you have ever had work under you at a company?

Microsoft is huge. How many people at Microsoft have 1,000 people under them? You argument about them being a huge company matters little. Huge companies also don't allow people to grow into rolls where 1,000 people are under them if they are "failed". Sure, it happens, but in general, if you rise to have 1,000 people under you, then you had a lot of success and accomplishments along the way.  When you make statements like that, it has no relevance to the discussion and just comes across as sour grapes. To me, I won't even read the rest of what you wrote as making that statement shows you are unable to be objective in your views and analysis.  If you want people to respect what you write, then be respectful in your writing.

Go on and on? A list of what people without experience fear serves no purpose in your credibility with me. In my experience, people who specify "ceramic saftey capacitors" and "no saftey resistors" know how to spell "safety". Can you tell me the difference between a computer grade "vertical-chip capacitor" and an audio capacitor? I doubt my EEs know, perhaps they could learn something.

Perhaps you can share how if you measure a box, that happens to be a DAC, you are not measuring "the total sum of parts inside the electronics, but the DAC chip at the engineering standard itself".  How could the equipment doing the measuring of the box measure anything but the total sum of the parts?  Your statement is not logical.

I am not an EE, but I have a bunch working for me and I am quite aware of the processes and decision trees they use to achieve the results we have targeted and it is not to throw out a laundry list of fears. I would suggest not doing the same for speakers. That is an area I know very well.

It is good to be critical of any form of review, whether a listening test or even a measurement to ensure what was done is accurate and representative. However, your last post is not a reasoned critique addressing specific elements. It is an appeal. It does more to justify ASRs existence than it does to discredit it.

A critique would be calling into question the Klippel testing that was done of a large panel speaker.  While Klippel can still provide highly accurate measurements of a speaker such as this, the test procedure must be modified, not just in the number of measurement points (which was done), but also the measurement cloud locations (and distance). This relates, as Amir has noted, to the accuracy of the model, but that accuracy figure is based on assumptions of what is being measured, so both need to be adapted and accurate  to accurately assess the error band. As well, the calculated summaries such as predicted room response, reflections, etc. must be adapted when a source is large enough to behave as a line array in the room it will be installed in or they will be grossly inaccurate at the listening position.

@mastering92 , I could not have proven my point better, if I had written your post myself. If you are going to attempt to discredit someone online, including me, I would recommended what you write being accurate, supportable, and relevant. Making false claims about someone's career, questioning someone's equipment when it is among the best available, and then following up with a series of statements related to technical information, that are either not logical or not defensible is not a successful path. I have issues with some of the work ASR has done and I can clearly, concisely, accurately, and defensibly state it. I also recognize that does not negate piece of their work.

@kota1 ,

What point are you trying to make. You know we are in agreement, that we both feel Amir's room is a bit of a disaster, though the smooth dispersion of the Revels will help.

The speakers are measured with a device that measures totally independent of the room it is in. It is equivalent to putting it in a large and very good anechoic chamber.

What other measurement are you expecting?
