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?

What is your definition of a "best" loudspeaker. How about the loudspeaker that makes you think you are listening to live music. The Cain & Cain single horns or the Zingali Overture 4's or the Wilson Benesch Curves. To name a few. Unless you have spent over $15000 you better say that you have a tube amplifier. I haven't heard any solid state amps that sound like live music. How come all those really good microphones are tubed?
For me, the dynamic and slam is the taste. Thus the Montana KAS tower speakers by PBN(Peter Noerbeck). Boasting 7 way system per side - twin 12" woofer, dual 9" mid's, dual 5" upper mids, and a tweeter in vertical array(dapolito). All scan speak components. Weighs in at 300 lbs per side. 4 monoblocks of 500 watts amps will produce bigger and better than live event.
Apogee Diva's 20 years ago at a HiFi show in London. I can still remember the incredible lifelike sound reproduction. Well, at least I think I can!
I can say with no doubt, that the Green Mountain
C-3 is the best speaker I have ever heard anywhere.

More later as they break in.
