The best speaker you ever heard?


In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?

Wow, that's one heck of a set up. Heard it many times and absolutely love that combo better than any of the AR electronics.
The best speakers to my ears were the Focal Diablo Utopias running from Devialet Expert 220 Pro. 

My region doesn't have access to all the brands, so there is that. 
Double stacked Quad 57's, Decca Kelly ribbon tweeters 10khz up, 24" Hartley Woofers <100hz mounted in the rear brick wall with the room behind as a speaker box.
All driven by a struggling 2 man lift water cooled Pure Class-A behemoth solid state amp.

Not that I could ever afford it.

I was almost on the edge of tears.
