Yeah I'll give Andy a call. I've been very curious about Andy's berylium tweeter when he came out with the 2 way floorstander at CES last year. I'm a fan of the soft dome Scanspeak revelator since I probably sit a bit closer to the speakers than optimal (my speakers on on the long wall), and wondering if the Berylium tweeter would give out more energy than the current one. I'm of course stereotyping here (soft dome = less energy, metal = more).
