Thiel 2.3 vs 2.4 the real difference

Did anyone took the mid/tweeter driver out of the CS2.4? I am just curious if Thiel really make the drivers themselves as it is not viable to manufacture a relative small number themselves or, what I suspect, Thiel is installing a(n) (OEM) version of a known brand like SEAS or Dynaudio in the CS2.4

The rationale behind it is to get a cheap(er) CS2.3 and mount CS2.4 mid/tweeters.
There is a good reason that Thiel wouldnt sell the CS2.4 coaxial drivers by themselves or put them in a CS2.3

Thiel used to use outsourced drivers that were modified to Thiels specs. They've been using their own drivers for some time now. The most recent ones, such as those used on the 3.7's are clearly very different than those used by others.

That 2.4 mid/high driver is very different from others manufactured by the company. There is no electronic crossover but instead a physical transfer is designed between the two drivers (common coil used) based on the polymer that couples/uncouples these two portions of the driver depending on the frequency.

This is a superb forward thinking design with excellent coherence and minimal phase shift in the transfer region.

Excellent discussion- guys. I will add that the CS 2.4 gets timbre "right".
I do not know if the older models exact this difference? Happy Listening!

I own 2.4's. The only real issue I have is the "kick drum range". It doesn't do that super well like it does the rest of the range. I have them paired with it an REL sub. Which fills out the lower range well but doesn't really give you the "thwack" of the kick drum. 

Other than that, to make them work you need high current amps and good sources. To that end I have a VPI Prime with Parasonnd JC3+ and Dynavector 20x2 lo mc cart going to a BAT pre and Parasound A21 amp. 

The speakers are transparent with air, and 3D as well.
