Looks capable, very nice datasheet in general, but is really expensive:

Same price class than the Purify 10", but two specialized variations instead of one model type. Purify has wider bandwidth than each of both models, specialized Kartesian variants might have advantages for specific applications - measurements from the datasheet are excellent.
(Kartesian may have more SD modulation, but gives less eye cancer - I really do not like the Purify surround visually...)

They also have extended their 7" woofers line:

I really like that cool motor and the platform they build with it.

Very expensive, but I do like the sensitivity level for these drivers, especially at the 6-8omh impedance level.

Yes impressive specs, and beautiful motors, would look very cool in nudes or OB.
I’m so satisfied with the mid120 that I keep looking at their woofers or subs for a current 3 way project (inspired by your thread Kwesi btw).
But too high end for my level as I’m not sure I would extract all their value, but it’s entertaining, maybe one day.
They are expensive, but comparable to top Seas/Scan’/Purifi/and some PA brands, + I’d be ok to pay more for a company so open about their tech and knowledge.
And cherry on the cake, they're french!

Also, they should really clean up their web pages naming structure, maybe they didn’t expected to be shared much but it’s a mess, not very pro but it’s a detail.

They looks great on paper. Now we need these in 12" and 15" versions. 😎

 

[picowallspeaker]

Why? A 10" is already too big

 

[YSDR]

Why not?
Anyway, if the 10" is too large for you, use the 6.5".

 

[picowallspeaker]

What doesn't fit in your requests in this 10"? The size? So why would you participate in a presentation of a 10" woofer? Do you have some secret techniques to give to the manufacturer to enlarge their cones?

 

[YSDR]

I just said that these are very impressive drivers (at least on paper) and would be great to see even larger ones with similar low distortions. If it's not happens in the future then need to choose drivers from other manufacturer, if someone wants larger cones. Why bigger? Just because.
Sorry, I didn't wanted to offend the thread!

 

[phase_accurate]

Yes, this 15" would be sexy:

Yes but the Kardasians have a bigger low end!

I often wonder what makes a loudspeaker expensive? I don’t want to derail this thread, maybe I’ll start another one on loudspeaker costs. I’m sure there is a lot in design cost, sometimes I think the manufacturers just get lucky. The Purify have remarkable specs, published distortion graphs, and obvious attempts at improving the sound that may cause eye cancer. Good for them! On the other hand Scan Speak and Morel seem to make mostly the same stuff year after year. Sometimes designers come up with strange things like elliptical tweeters and magnets of two materials, but we rarely see distortion specs, just claims of low distortion. The Kartesians look nice, I’m skeptical of the graphs though. They look too nice, like my first girlfriend did.

Plus this was never proven with actual data and measurements anywhere to begin with.
It's just only a hypothesis at this point with not real connection to how significant that problem even is.

Having done some calculation myself, I find it really difficult to believe that it will be very significant.

Just on paper the vKi range looks a lot more promising, mostly because they are more optimized for what they do, instead of trying to get just one driver trying to do it all.
Although they have variants that fit in that range as well.

there was a big server farm crash 1 or 2 years ago .. not their fault!

but it is annoying to read "cooper" instead of copper ... should be corrected in future releases!

“Kartesian may have more SD modulation, but gives less eye cancer - I really do not like the Purify surround visually...”

This is what Kartesian comment on Sd modulation: "Sd modulation is minor issue to be considered on mid woofer (not subwoofer). Our solution for it is the Omega surround. Part of the surround is hidden and used only in larger excursion."
