beryllium vs diamond

Hifi, who said that? From what I can see only a couple of manufacturers
are using that material in the car audio industry. Secondly, Zylon has been
around since the 80's. If it is so good, why aren't any high end speaker
manufacturers using that material 30 years later? Also can you comment
on the specific weight, strength & gravity of Zylon vs Diamond, beryllium &
diamond-coated beryllium?

I can say Magico's new hybrid Nano-Graphene/carbon Nano-tec
diaphragms are almost 30% light and 300% stiffer than the previous
generation. So that company are not standing still.

Melbguy1, Yamaha is saying this and everybody will find out when they bring their new Yamaha NS 5000's on the market at the end of July, 2016!.. I can't wait until some of the "magazine reviewers" review these speakers!!..

Here's some pictures of the inside of these speakers..you can ENLARGE these PICTURES below also so you get a closer look!..

These speakers will cost around $12K U.S.A. and all three speaker drivers are made of Zylon too!..

Yamaha is not high end.

I think the new ribbontweeter of the outcomming Monitor Audio Platinum will outperfrom both. I can explain why.

The new ribbontweeter is bigger and wider. First of all it is opener than both the diamond and beryllium tweeter. I compared the Platinum with the diamond D2 and the stage of the Platinum is wider and deeper. Beside this the individual focus of voices and instruments is sharper.

The new one will have a lot more authority than the Platinum at this moment. We do a lot of research these days in sound&vision.

With the ribbontweeter you can create a holographic stage to die for. This is not possible with both of these tweeters. The stage is not only deeper and wider, but it can even create more space in front of the speakers.

I give an example: Miles Davis/Kinf of Blue. The piano on the right site owns the shape of a piano. The same about the drums on the right. It plays fully free beside and in front of the speakers. Also the presentation of the height of the cymbals is more impressive.

Melbguy1, The "working man" will disagree with that statement ABOVE!..
