I think the breakup is still there- but a valley instead of a peak. It's apparent by looking at the off-axis graphs with dips between 30KHz-40Khz.
But never mind. It's technically perfect to 20KHz, IMHO. In fact, the top octave (10Khz-20Khz) is over-rated.Comment

Top class response but the harmonic are only slightly better than Satori line and they will most likely be asking much more...
Great driver but not a giant killer!

At half the price, I suspect that it's not a giant killer, but it simply becomes a giant. ScanSpeak still sells lots of $200+ woofers despite SBA/Satori. Purifi would sell a bunch of these at $250-ish. At $450, it may become a darling for the boutique speaker manufacturers, but we'll see how/whether it can dislodge SS in its niche.Welcome to Rivendell, Mr. Anderson.Comment

As far a I can see, this is state of the art for 2020.
I'm a member of Hificompass.com, and when I log-in I can compare up to 3 drivers, side by side.
Is it better than the Satori MW16P? Yes?
Is it better than SS Ellipticor, Accuton and AudioTechnology, SEAS Excel Graphene.
It appears to me, yes!
Sure, the value proposition of all this unit is low. But so it are the others.
But the performance of the Purifi is there.
Good:
Flat and smooth on axis and off axis - check
No cone edge resonance- check
No fierce breakup- check
Plenty of excursion- check
Excellent nonlinear distortion- check
Bed:
Sensitivity- slightly lower than average
Ugly:
Single unit DIY pricing is high.
Summary-
Bends the rule- there's no replacement for displacement- better than 8 or 9" woofers
Bends the rule- ultra low linear distortion AND linear distortion in the midrange.
Lay terms: Will play cleaner, clearer and louder! Does excellent bass AND excellent midrange.

Sure looks like a potent driver. I'd envision another 2.5way project with these, but that would need 4 + nice beryllium tweeters to pair with to live up to the base performance of these... that means quite many EUR so needs some planning ahead. Nice to know there is something like this to dream towards

Some speaker driver measurements...
Agreed.
It’s definitely a better driver than the others but not by that much! I mean, distortion wise how much better is it really in absolute value. 5% overall maybe? I’m too lazy to run the numbers...
And that 10mm figure is still to be proven. Manufacturer tend to take there numbers from the marketing department. Keep an eye on Dickason review! I’m sure someone will post it soon enough.
That being said, just to be clear:
>>> It is a GIANT and SOTA!
Just a very expensive one and personally care more about my money than those last few percents of performance... even if I could afford it which I can’t (obviously)!!!
My thinking : why buy only one Bugatti Chiron when for that same price you can have a Corvette C8, an Acura NSX, a Lamborghini and a Tesla Roadster.

It does what we hoped, and thought, it would do. It's too expensive. The bulk pricing for 10+ units should be the price for one.
A comparison with textreme will be interesting.
As I originally said a while back the proposition of a single one of these in a small cabinet, active system, with Purifi amplifiers is a big one. That's a small system with big sound and in a way that no other driver would appear to be able to do. Not that other drivers wouldn't be capable they just haven't been designed that way and hence aren't available. This is a very niche product and the only similar competitors from the past would be the anarchy and the scan speak illuminator 7" drivers. Sure neither of those are quite as good as the Purifi woofer but they are similar. Neither of those shook up the industry or the DIY sector. They ended up seldom used but always praised when used correctly.
The main issue here is price. If they cost the same as SBs standard range then no one would have a reason to go with anything else when after a 6-7" woofer.
As it stands, for a lower price woofer, you're still going to go with Dayton Audio or SB Acoustics. If you want a genuine improvement in performance and have more to spend then you'll go with a Satori. If you have the room then a small sub plus Satori would be the obvious choice in keeping with the small main speaker form factor. If you can go bigger than a 6" woofer then you'll never go with the Purifi as bigger 3 ways will give you more performance and bang for your buck.
I mean yes the Purifi has slightly better midrange non linear performance Vs a Satori but, and I say this as the biggest non linear distortion proponent on the planet, you are not going to hear this. Plus the textreme would appear to potentially lower non linear HD too.
Basically we're back to the - if it has to be small and you cannot add a small sub under the couch or in a corner, then the Purifi is the obvious, but expensive, option.
I do like the proposition of a slim three way tower with several of these stacked in a line plus a suitable midrange, or a coax like the SEAS C18. It'd look very stylish and have excellent performance. Still you'd be better off with multiple subs but then you always are.
Not to be a harsh critic for SEAS but their graphene drivers are not looking appealing at all with these now being released and with the textreme Satori on the way.What you screamin' for, every five minutes there's a bomb or something. I'm leavin' Bzzzzzzz!

The measurements of the "entry level" ScanSpeak Ellipticor 18WE/4542T00 midwoofer:
ScanSpeak Ellipticor 18WE/4542T00 | HiFiCompassComment

“Entry level”?
In Australian English that means the baseline.
This looks like SOTA performance. Nothing to complain about, apart from the outrageous retail price.
Here’s my analysis:
The good:
Extraordinary magnet system aesthetics and construction quality
Probably good reliability in supply and consistency (based on Scan-Speak heritage)
Higher sensitivity compared to the Purifi 6.5” (needs half the wattage drive to reach same SPL)
Excellent midrange and midbass; equally suited to for 3 way or 2 way applications.
The bad:
Where did my money go?
(Twice as expensive as the Purifi, which everyone already thinks is too expensive)
The ugly:
Ordinary looking paper cone with oval eyeball dust cap.
How’s it sound?
? Cleaner than the Purifi for pure midrange applications (The lower H4 & H5 suggest even lower higher order harmonic distortions (H6-H9)
Summary- 6.5” paper cone driver pushed to the limits.
All things considered-
Given the current state of the world Moving towards miniaturisation; where a 5.25” driver is put into a 1/4 cu foot box is a “subwoofers“; I consider the Purifi 6.5” the winner.Comment

Tim Feleppa had a similar result- the RS52FN-8
model is not in the same level of excellence as the RS52AN-8
It's hard to say if the differences between these (RS52FN-8) drivers and the aluminium ones I have can be put down to the dome material or the difference in manufacturing facility (China vs. India). Assuming my results are indicative of the current crop of drivers, I'd recommend the aluminium RS52 over this.Comment

Classically, Elton has made some drivers with very good cone assemblies, but I have yet to see an Elton driver with a well designed motor.
The 12-680 follows that path. The impedance curve tells part of the story at a glance.DFAL

How is Audio HiFi as a vendor? Reputable? I'm waiting on the T25 release for a project, but I could easily use the T34 if I had a substantially different economic exchange than what Solen is wanting.https://audio-hi.fi/index.php?main_p...eyword=bliesma
