Thiel Owners

andy - your reservations regarding high-power output from the model 2 are valid. Small drivers with relatively low-frequency crosspoints serve to simulate a point source, with off axis / room energy being correctly associated with on-axis / direct energy. A real singer, drum, etc. in your playback room would act like a point source.

The model 2 has never been able to play as loud or deep as the model 3 and above. That's the main reasons it costs so much less. If you like Thiel and want louder, find a series 3 or higher.

jon - the ATC with a 3" midrange can play loud because it is crossed over much higher and steeper. Trade-offs. Physics rules.

Step response and square wave response are good indications of time accuracy.

I am of the thought that only infinite baffles (sealed boxes) and true transmission lines (which for full range speakers would be ginormous!) can be truly time coherent.

@tom, the crossover is much steeper but the ATC mid is crossed over at 380 while the CS2.4 is at 800.  Since it was created as a pro driver it was made for loud volume, reliability, temperature stability.

Hi Tom,
Actually I am pretty happy with my the CS2.4.  I only brought up the discussion to illustrate differences in design philosophy.  Also before I didn't quite know the reason behind different model naming convention.  Now I know 2 vs 3 denotes the size of the mid range driver and may be the bass driver as well.
