It's the argument itself that is important, not the person making it.
And why do you assume that I haven't done all this?
That indeed made huge steps in the progress of audio.
Exactly.
But on forums like this it's difficult to do as human communication is mostly body language. And here we just have words.
Nope the results of design/modifications are what is important.
By the nature and tone of your answering it is uncertain of your training and expertise, I did ask
Please understand that I am not being at all confrontational, I am attempting to share knowledge and observations with you and for your benefit. If you were to try the magnet/aluminium foil experiment you might learn something, what's stopping you ?.

This thread is about Purifi Audio and their stuff Max, not your goop or other crazy theories. If you don't want people to challenge you on your highly implausible observations then don't post them.

You may be right. The effects shown are probably solely due to hysteresis. The effects of Barkhausen noise are probably more subtle and not easily seen in such a Diagramm.

Not really Patrick, you will see that I take no position here other than trying to communicate what I learned.
The facts seem genuine to me. For instance, it is easily seen that the effective piston area varies with excursion due to the surround stretching and compressing, which necessarily must lead to distortion.
Whether that new surround a) solves the issue and/or b) leads to audible difference, I don't know.
I do know that in measurements which I posted earlier, the improvement is obvious as lower distortion.
But I will admit that sometimes I wished I had Bruno's brain, if only the left side that is 😎

And yet - you have been proven wrong and delusional so many time on this forum - but you keep insisting on that you are fit to offer "knowledge and observations"...
Shame!

So go ahead please state these 'crazy theories' that you ascribe to me, I am interested to hear of such theories. While you are at it please detail these 'highly implausible observations', that would be educational to me too. Both these tasks require a reference of some sort, you might like to explain your reference belief system that gives rise to your exclamation.

I don't even trust myself.
Or rather, I have absolute trust in my malfunctioning memory, and my ability to completely forget any/all previous events at random.
Depends on perspective.
OK, but speaking of facts this is a problem only when a small cone is used where a larger one might otherwise be. Possibly to the fourth power.
Exactly, and the stated goal of all their deliberations is to design a small, long stroke driver that performs as a good as a large short stroke driver!

Yes, the compromise here is size. There's no way that it can "perform as good" though surely regards doppler distortion?
As Bill said, always a compromise. Is the doppler distortion more or less audible than the 'granularity' of the magnetic part, or of the distortion due to changing effective piston diameter?
A good designer will try to find the best combination of trade-offs that still gives him an increase in performance wrt the current state of the art. He/she does that through an advanced technique called 'engineering'. 😎
And the final arbiter is the market - the best survey is a signed purchase order.
