The impulse response shows the peaks
for the drivers are very close together,
indicating that the time alignment design
of this speaker is working. In the bottom
plot, the time interval between the
vertical red line on the left, and the 2.8
ms line on the right, is 2.8 - 2.229 =
0.571 ms.
Impedance/Phase results show that the
impedance stays down around 4 Ohms
at 100 Hz and above, while the electrical
0
phase is within + 30
the audible frequency range. Don't try
and drive these speakers with a mass
market receiver. At least 200 watts RMS
per channel into 8 Ohms, with a rating
into 4 Ohms, will be a good choice.

Conclusions
Thiel's new CS2.4 speakers are superb.
They have no noticeable tonality
aberrations, i.e., they sound neutral
throughout their range, they have a big
soundstage, and have marvelous detail.
They will undoubtedly be one of the
great speaker introductions of 2003. At
their price, I have never heard anything
better, and many are not nearly as
good. They are beautifully constructed
and pleasing to the eye. Recommending
the CS2.4s is one of the easiest jobs I
have had to date.
