I find it strange that this speaker does not catch more interest, if there is one speaker to audition within the next year, this is it....
The top model CS 3.7 was the culmination of a whole lifetime of speaker design for late Mr Jim Thiel, he spent a lifetime learning what he did so he could make his ultimate statement, the CS 3.7 became som good that it immediately obsoleted all the more expensive models.
CS 2.7 uses the exact same mid/tweeter as the 3.7, there's years upon years upon years of research behind the drivers, cabinets, crossovers and... well everything in these speakers.
It seems like noone in this forum cares about time/phase coherence and in my opinion Gene and all the others is wrong about this, it may take a long time to actually learn to appreciate the beauty of a time/phase coherent speaker. In my case it was > 1/2 year until I realized the full potential, but for me it's probably no way back
Speakers must be phase/time coherent, this may be the speaker of the year if you ask me
