Thiel 2.3 vs 2.4 the real difference

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. 

Good to see you-last_lemming.

Thanks! for sharing your thoughts. Keep me posted as you go to a B.A.T. pre-amp. I cannot suggest enough a  REL subwoofer as well.
