prof gives a very nice over view of the CS 2.7. During my auditioning sessions I found it this model to act as a slightly scaled down version of the CS 3.7 loudspeaker for those that did not have a larger listening space. Both models do feature Jim's last design-the wavy driver concept as above. The curved plywood walls are beautiful as well.
To address the 2.7 vs. the CS 2.4, I venture to report that the CS 2.7 has a little more weight authority in the Bass department. Wavy driver vs. passive radiator. Both feature that wonderful Thiel house sound that we all know and love (richest timbre, soundstage and micro details in the music). Hope this information has been helpful to you.
Happy Listening!
