Welcome to AC! I'm from lower Michigan too (110 miles to the northeast of Kazoo).
Apparently the Pesdistale uses a TMM design and the CST-1 a MTM layout. Not a particular fan of MTM. I've found the principle requires listening at exactly equal distance between the midrange drivers to avoid them canceling each other out. And the CST-1, being angled backwards would require the listening position to be steadily rising the farther back you go. Am a fan of transmission line (TL, own/use a pair) but am more than curious why their design is a secret and how a single TL can properly serve two drivers. Can't find any particulars for the Pesdistale.
Enjoy The Music's November 2012 review of the CST-1 by Colin Flood quotes "after a few months of letting them meld into your room"?? And later in the review "flat 2dB response 20-20,000 Hz, down 3dB at 40 Hz" (stated response is 40-20,000 Hz). And "the Skates also used an interior folded transmission line" (where else would the TL be located?
SoundStage Hi-Fi December 2011 review of the CST-1 mentions the advantages of TL but also it's downfall (complexity to build). I'm so tired of reading that. The only pair of speakers I ever built were TL and the veneering was much more challenging than the cabinet itself. Note that bass extension and efficiency specifications vary slightly from the above review.
