I once had a business in the field of loudspeaker development, after working with a company, OEM only, for two years. I'm a natural scientist by education. Additionally I studied mathematics, chemistry, AI, social sciences, and was in economics for a year. I hang around with artist and musicians...

Personality cult? I'm afraid I have to ask this, but shouldn't such an examination take place before the release? I mean, somebody had a little dream come true for a lot of dollars. It's kind of a bust for now. I think that's a pity. ( I wouldn't be so hasty because of the technical reason...

A Freudian slip? -- good or odd ? -- I couldn't resist, sorry. Do You say something like "measures bad, sounds good"? Or do You expect this speaker to be out of specs, defective? Usually sound engineers are not interested in loudspeakers. They simply have to work. These people have other...

Ja, now include the phases of the moon and we have arrived. Pardon the sarcasm, but there comes a time when that relativization stops. Sorry again, but this relativization of the mischief can be a real pain in the neck. If the measurements made are valid, then this is simply crap. You just...

I listed some numbers above. I have to correct them down by 6dB. The reason is a wrong specification of the maximum excursion in WinISD. So there is still 70dB average level left if you want to have about 15dB dynamic - in one meter distance mind you. This is really not much. Especially the bass...

Yep, I recommended to not push such little drivers way beyond their limit. But, in this very case the WinISD simulation software predicts a limit well above 96dB (2pi) / 90dB (4pi) from 50Hz (!!) on. We have 4pi conditions here. So, at least the 86dB-measurement doesn't show that much of...

Puh! This is a personal offense. Many of my posts should reveal some, in audiophilia maybe unfamiliar, understanding of the topic. Ironically I have a deeper problem with a lack of it. You get the logic? There are still so many unanswered questions. I only discuss them, or rather try to discuss...

So, the latter curve doesn't include the interference with baffle reflections, right? Don't You think that's a bit pedestrian? Btw, which is Your leading ear? Everybody has a leading ear. Which is Your side of preference, left or right?

Thank You, I take that. But I'm out anyway. You know, first You try to sport some humor. But sooner than later it becomes sour. Sometimes it feels as if audiophiles in their well-known pedantry (Sigmund had a very German word for it) use "science" as a new toy. That would be exactly the same as...

So it's a diagram of something you need to come up with a story about. Where does it come from? What is it? Anyway, this only convinces those who no longer need to be convinced, but are to be confirmed. I'm missing energy since my 80th birthday. You are way younger, sure. There are still...

If one thinks of 70dB to be very high of a level. See https://croweaudio.blogspot.com/2020/06/horn-no-1155-for-raal-70-20xr-pure.html mentioned here: https://www.audiosciencereview.com/forum/index.php?threads/horn-loading-raal-ribbon-tweeter-full-measurement-comparison.14457/ ( Regarding an...

Hm, lost in translation? Referring to Your recommendation, to mitigate a "collapsing directivity"-- how would you flatten the bass and the mids, but leave the treble untouched? Just a thought experiment.

Twisted logic? You'd have to muffle the bass and also the mids, but leave the treble untouched. How? You sell room treatment commercially. As an expert, what do you recommend to accomplish the task?

If I could not imagine that the theory of preference, so celebrated here, would need an addition, then the term 'science' would probably be inappropriate. I think the 'science' should be clarified in several places. Conceptually I am not quite clear what 'preference' means. The term seems to be...

What I wanted to say was that I am not interested in the personnel of hearing tests. They don't know anything about music. they rate the loudspeakers according to their expectations. the quality of experience of the situation - it's actually known what I mean by that? The mindset - is probably...

Please do not accuse me of not knowing the stuff. My previous caveat against Your argumentation remains valid, nothing to add. Only so much, that the latest measurement, which was unrelated, showed two totally different speakers. They differ not only in the onset of directivity, but in its...

@pozz, please don't take offense, really. Just another "paper" of no further interest. The "paper" only tells, that a bigger part of distortion is generated in the motor. Period. Again sorry, @pozz. Thank You anyway.

Gotcha! Again a re-use of other measurement. So now I'm supposed to imagine that you're right. Isn't that how it is? There are measurements, and I'm supposed to imagine something. Great, pedestrian science!

The same thing I said to Bjorn applies here. What in heaven can statistical tests tell us? That the population has got used to some crap and expects it to be perfected again and again? A good box is like my old one, but better! (Depending on how bad I think my old ones are now, there can and...

The data presented do not support your ideas. I'm not saying they're wrong. But the argument is flawed. This is because the data was not collected for the purpose of supporting your argument. In the audio field, people have become too accustomed to accepting incomplete or partially invented...
