any diffrence between triangle celius es and 202?

I'm 8 months late to this, but:

I owned the Triton 202s and then the Triton ES (as well as the Comete 202 and the Zerius 202). Based on that, my opinion is that the ES tweeters were way too loud. The 202 tweeters made for a more balanced-sounding speaker overall.

In any case, did you end up buying either?

Go for the Celius ESW if you can find one, or the ES. Triangle Electroacoustique continued to evolve this speaker line in positive ways over time. Flatter responses over freq. range, better ceramic tweeters, tighter bass.
