I've heard the 3.6 and 2.3, so this is subjective, in as much as these were the ones I liked/could afford at the time. The 3.6 didn't seem to "converge" the sound as well as the 2.3, even though the bass was deeper. For whatever reason, I felt the bass was seperated a little from the mid & tweter. This could have been due to sitting closer than eight feet from them also; I had a 9-foot distance from the 2.3's.
