What's the best mid-range driver available?

Don't remember the brand the the Mid Range driver in the verity Fidelio in Parsifal is pretty amazing... It's a 5 inch underhung damped polypropylene driver (it'a the same driver Sonus Faber use in the Guarneri but Verity tweated it a bit)...

Don't have the specs but I'm sure someone will come up with more info...

ATC makes the finest midrange driver in the world, as Soix said. i know there is as least one site that sells them to the public, through ATC.

Dunlavy V's have Domes by Vifa they sound excellent to me.

*ATC WORLD CLASS* END OF STORY !!!!!!!!!!!!

Here is a link for the spec's on the ATC
