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?

The new ProAc K3 and K6's ! 
 
ProAc has got these boxes tuned just right and your music sounds so uncanny Real.. much like you hear at a Live Concert !  

I don't hear this when listening to the Magico A5's or M6's or Vivid Audio and others I've heard in the past. 

 This could be End-Game speakers for a lot of us ! 

 
20 year old thread and while I was skipping a page here and there I didn’t see votes for the speakers that impressed me the most. Usually my favorite is the pair I just sold til my ears get used to the pair I have then within a year or so I find something, some characteristic that breaks the spell and the cycle restarts. 
All rounder: Snell A/III

What they got right: Amazing top to bottom integration, tremendous bass, perfect imaging, great off axis. Imagine the combination of Wilson’s bass plus Martin Logan's imaging but without tonal exaggerations anywhere to be found.

Amazing imaging: Early Martin Logal full range ESLs. Terrible tonal balance compared to today’s standards.
I agree with erik squires! The Snell Type A's are still a world champion speaker even 44 years later. Peter Snell got the "magic" right using three drivers in a sealed box! I have a pair from the original owner!
