Have you ever heard a set of EnABLed drivers vrs not? If you have not your comment is a guess.

Can you please explain how this blind A/B testing was performed?
Why ? why is the onus on him to prove something to you?
We all hear differently. Since all speakers are flawed, the designers must prioritize some aspects of performance over other aspects. We all have preferences of which aspect of sound reproduction is most important to us. It is very difficult to assign a physical phenomenon as a cause for some small nuanced difference that we hear. If I think speaker A sounds a little more harsh than speaker B with on a certain tract of music, it is very challenging to discover what, exactly, is causing this perception of harshness. If Speaker B has a more realistic bass response, better dynamics, more punchy, it is (again) challenging to find an exact cause.
If a person who has been listening to wide band drivers for many years, tells me that these dots make a difference, I am inclined to extend him the benefit of the doubt. I assume he is hearing something real, even if we don't yet know how to measure the phenomenon... or more precisely stated, we don't know which of the hundreds of different measurements is the meaningful one in this particular case.

Have fun with the interpretation

Sensitivity matched loudspeakers hidden behind an opaque screen, Ampliier with an AB switch box. iMac as sourcen witha playlost of well-recorded tracks. Set up by one person. Then over the space of day individuals could go listen and fill out a survey. There wer esome who couldn’t tell. The rest came down with the boxes with EnABLed drivers. I could tell in a single switch but uusally take a couple more just to ensure my choice. Once you know what to listen for it is pretty easy.

As far as I know, those measurements were done on the fully EnABLed cones - which include prior coating on the whole cone area, and only after that, applying those funny ringlets/dots on the already coated cone. Am I right?
Please present measurements about EnABL ringlets/dots only (without any other cone coating!), before and after, on the same driver. Also, for further comparison - random lines on the cone drew with the same EnABL ink, with the same total length as EnABL ringlets/dots. This is to exclude the mass difference between inked and not inked cone.

Because he is advertising EnABL snake oil dots as a magical panacea in every possible thread about loudspeakers.
But we will do know, if someone present any measurement, even just one comparison with any difference, between original cone and EnABL snake oil dots on it. Without additional cone coatings, of course.

It could be that the outer edge of the diaphragm also has some change (along with the the way the surround and adhesive reacts to it), but most of the measurable change is the spider and surround.
-so yes, metal/*ceramic cone drivers have break-in.
*also, most ceramic cones are deep anodized aluminum - so still aluminum cones at their core. Accuton (most older parts) would be an exception (not the newer "cell" drivers that have aluminum honeycomb cores).
What measurement type would you suggest, and how would it be sensitive enough to prove/disprove the observations?
Only i did that, and none of those drivers were supplied by me.
And never more than just EnABL on the metel cone Alpairs.

Now I paid attention (to late!) to the text below the measurements - they are comparing TWO DIFFERENT drivers (inked and not inked), not the same driver before and after EnABL!!!
Those measurements are not relevant, they present usual production difference between drivers!!!

I have plenty of experience in debunking snake oil scams.
Many people have already used their ears for measurement. Is that not good enough?
Trouble is, if you have no theoretical concept of how the cone materials might change over time with repeated vibration, then why should you doubt the veracity of a camera measurement that accurately measures the colour of the cone?
You can not measure with ears, people invented instruments/equipment for measurements. But you can measure the ears and what ears hear.
Ears are good (excellent!) enough only in subjective, carefully conducted double-blind level-matched test, with the same speaker - regular and with EnABL dots.
You can not hear the colour of the cone. Synesthetes may argue on this, though.
I don't need to invent the theoretical concept, I happily will accept the measured difference, if any. The trouble is - nobody presented such measured difference.

Untrue. I have not been selling EnABLed drivers for some time now, failure of my eyesite during surgery. So nothing to advertise.
But that does not stop it from working.

But…
To quote Floyd Toole:
We are not building a hifi to entertain the measure kit, we ar edoing it to satisfy the soul.
Truth be told, some of your snake oil theories are snake oil.

Exactly All existing drivers in the known universe ”breaks in”, and changes over time, and with usage. And finally, given enough time, they all break down.
This is simply undisputable physics.
This can be really hard to understand for some of the truely uneducated, and fact resistant newbies that are more or less tone deaf, without real experience in the subject at hand.
