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?

Zu Definition 1.5. No crossover between 40 HZ and 12Khz provides impeccable phase coherence where it matters. Speaker is solid and implacable to 16 Hz because of 4 ten inch powered woofers per speaker. This may sound gimmicky to you but I assure that it is the result of original, substantial and considered engineering. Add in a nearly resistive 6 ohm load and 101 db efficiency and you are approaching the ideal. Check em out.
The Legacy Whispers with Legacy subs, driven by VTL pre/amp combo. Source was an SME table and arm but not sure which one. I wont stop until I can get close to the beautiful music I heard that afternoon.
Revel Salon driven by Levinson gear at a dealer in NYC a few years ago. With the prices of used Salon's getting more and more resonable it sure is tempting......but I'm pretty impressed with the sound that I'm now getting with my Energy V2.4i's and Talon Roc2002 sub. Funny how once you have a kid, the gear you already have starts to sound really nice.
