Advantages of beryllium?

I’m a millennial hipster idiot. I bought Harbeth P3ESR and some Rega stuff if that counts as a start of saving it...

You're quite right about the dispersion and waterfall. They say a lot. That Magico is a stunning achievement. As JA said in the measurements for the 936, it's measurements wouldn't be out of place in an expensive speaker. That it costs just $4000 makes it an excellent value. And as we can see from the raw data, even Focals better stuff doesn't measure a whole lot better. 

So......

You're more than welcome to claim I'm arguing about speaker prices, though that really is a canard as well as intellectually dishonest. And you can argue JA has some slanted opinion, which I find every reviewer does. It's my job to discern that slant and interpret what his description might translate into through my ears. Regardless, his opinion has very little influence on how a computer measures a speaker. He cannot will the microphone to detect what isn't there. Another canard tossed out there on your part. Like what you like. Try sticking to facts you can actually back up though. 

kosst_amojan still waiting for you to point out a modern BE compression driver with better specs than TAD? But maybe all you had was a rude reply and ignorant comment.   And for the rest this maybe of interest http://www.audioxpress.com/article/Voice-Coil-Spotlight-The-Beryllium-Advantage

@willemj I hope it isn't dying.  The resurgence of vinyl combined with cheaper bandwidth and data storage allow for higher quality digital recordings where mp3 was the norm.  The baby boomers are going to impact every aspect of every market because of the population size.  What has changed is how people listen to music.  It no longer has to be sitting in front of speakers or tied to a large component unless you're listening to vinyl.  Music listening is mobile and I think there are more people listening to music because of that than ever before.

@defiantboomerang I wouldn't worry about beryllium's toxicity in speakers.  The speaker mfgs like Persona and Focal use a shield over them to ensure a kid doesn't go poke them open and inhale the dust.

I read a recent story about the diplomats that were stationed in Cuba and lost their hearing, apparently due to some very high frequency sounds. Apparently those frequencies were generated by metal dome tweeters. The highs break up above what most consider the upper limits of human hearing so they just produced sounds about that frequency and let that " break up " do the rest.
