Yes sorry, think of a Dr with a stethoscope plus like you say the amount of exciters.
I'd like to know how @Audiofrenzy did that. He appears to know how to do that, which might be an interesting method.
As a general point of information if you go to a members profile you can easily review all their posts and replies to posts.
I cant hear it for you, so you have to do it yourself. Nothing to it but to do it, do it, do it.🤣
I really don't want to get involved in this useless back and forth but I can't help myself here because the answer is so clear it should not be a topic of wasted discourse
Colouration is any shift away from the source sound caused by characteristics of the playback media. Whether the source sound has been manipulated or not has nothing to do with colouration
Amplifiers, speaker materials and construction can all affect the accuracy of the reproduced sound and the end user is not going to know unless direct comparison with the original source is possible
Differences in colouration between output devices is a different matter. The same notes from a spruce top guitar and a cedar top will sound different because the material affects the sound.
The playback media's function is to be able to maintain that difference without adding or subtracting from it.
onedsx determined that his panels influenced the recorded sounds rather than faithfully reproducing them.
I doubt that few of us are in a position to dispute it. I don't own studio monitors and even if I did, I wouldn't know if even they were colouring the reproduction
Can we move on to more rewarding topics?
Eucy
Can the human ear catch that "shift away from source sound"? How could a random listener know, what might be the "source sound"? For example, music made in the USA, and the listener is in Asia, or vice versa? Is it possible to catch colouration in this, for example, for the European ear?

Alright, it is somewhat fancy terminology. 🙂
Can you catch anything missing in that Korean music? The source sound not matching what you hear through your panels/sound system?
Not a finished one, just experimenting. Still not sold to this DM idea, but if you go back few months, you'd see what I'd been experimenting with, for example here #7,321 or here, #7,261 and you can check on the way. Its troubling that every DML maker had stopped producing them, maybe some niche producers are still there, but...
This summer, either I'll make one, or drop the whole idea. I've been doing lot of searching, finding on the way a working model Arcophon of 1924 (on the internet, of course) and to all kinds of pseudo-science ideas. Check back on this thread last 2 months to see what I've been experimenting on.
At the moment, I'm quite interested in Oliver Göbel's "bending wave loudspeaker" thanks to @@Sandasnickaren, and the other one is @sergiu2009's rubanoide clone. I might use the rubanoide motor to feed the DM panel. Only, don't know what I'd dig up in searching for patents. 🙂
Further to my post #8,353,
If you are interested in @sergiu2009's rubanoide, which is also a DML panel, only curved, you'd have to start from here, #202 and read all the way. That's an incredible thread, where people went out of their way to test, simulate other's work. And, finally @sergiu2009 finished it and using it for 5 or so years.

Ondesx,
Makes a very good point I have asked various members if they would post their panels to just play a 1KHz, 5KHz, and 10KHz sine wave through their panels. But no one will do that and my reasoning is that it will show the colorization of the panels. Each panel will show a unique and different harmonics . This is why it also sounds like someone is playing their music in a bathroom next door. If the goal of the signal chain is to reproduce the signal as it is being presented at the input and the output to represent this input as such only amplified.Why not the speaker when hooked up to the system? All the panels I have made and even the segmented sphere has not been able to do this. They never just show the fundamental sine wave, but a mixture of frequencies.
This is the same test that is used to analyze amplifiers to see the harmonic distortions that the amplifier is making and possible corrections one can make to its circuit to try and correct it to reduce the distortion. There are simple tests to show intermodulation distortion that one can do by playing to frequencies close together and looking at its FFT but alas no one will do this. They just like playing short music segments and say how good it sounds to them.
I guess I should go because I am not a real fanboy here hope you all find the sound you are looking for because in the end that all that matters....
Cheers.

Yes, I found that. 40mm thick panel,
I'm still trying to fathom what he's trying to say. 🙂
I think we're going to talk for a long time without ”understanding" each other, but anyway: I don't want to convince anyone. I want just to be sure that we’re talking of the same things...
Concerning your visit to an audio equipment dealer, I am sorry to tell you that your approach isn't the right one and your dealer should have lent you speakers to listen to, where they should be installed, taking care, of course, to respect the rules of their installation. This would already be a first step towards "real" HiFi reproduction. But it's still insufficient for a "purist" and moreover for a sound engineer!
Indeed, as you probably are aware, the last link in an audio system is the room in which the speakers are used: it is necessary to carry out a "passive" acoustic treatment of this room using absorbers and diffusers, and even use an "active" treatment with digital processors in order to correct the last residual acoustic defects as much as possible.
By the way, if you have ever had the opportunity to visit one or more recording studios, you must have been struck by the way they are all organized. And in particular the considerable amount of money they spend on "passive" treatment of the space (not all use an "active" processing yet). Personally, I noticed in particular how given recordings sounded very "similar" acoustically from one studio to another, while the monitors were sometimes very different. On the other hand, this same recordings on identical speakers from individuals sounded completely different from one listening room to another, without acoustic treatment!
This double result is not surprising, since studios follow AES standards and these standards lead to physical characteristics of the studios that are quite close, which is of course not the case of most private listening rooms. Besides, the mastered signal is what it is and, consequently, whatever the studio in which one is going to listen to this final result, one should hear this one and the same reference, that's what HiFi is all about: the most faithful reproduction possible of what the producers, sound engineers and artists have recorded!
Oh I forget to say that one of my daughters is a professional singer still in production yet. I recorded her in a lot of different theaters and even home.The tweaking of my listening room was made obviously by measurements, since a digital signal processor is the final electronic link of my audio system and by using then only… her voice !

Please read my answer to your other post in post #8358... It'll, hopefully, explain some confusion you make on audio reproduction...
I am very well aware of all the above and it changes nothing. In an identical environment playing an identical track three monitors with measurably the same response sounded different. I agree there is little value in continuing this conversation and wish you well in your efforts.
