The new version of the JM Lab Grande Utopia, the Grande Utopia Be has been released. This time, they're using a Beryllium tweeter, of all things. Here's a link with specific info about the tweeter: http://www.focal.tm.fr/gb/home/utopiabe/tek/Tweeter.htm And here's the main page for the speaker specs: http://www.focal.tm.fr/gb/home/utopiabe/caract.htm Interesting technology, but it still seems a bit "behind the times" for a high-end company like JM Lab to still be using dome tweeters (even if they are inverted). IMO, they should be using ribbons for tweeters. I'm quite sure the moving mass of a ribbon is still far less than this newfangled Beryllium tweeter. Discuss.
