Danger of Beryllium HF Driver Diaphragms (was Australian Diaphragms)

[Mike Edwards]

Hot topic!!! Having worked in the gas analysis and calibration fields I have had to handle many a form of potentially harmful materials such as; NOx, NO, Co, Me, So2, H2S. You get the picture. I was trained and qualified to work in an environment that had deadly potential for myself and others, I used precautions, often more than required, who knows what Bozo wrote the procedure with data that might later be proven incorrect? So, here is my call. If you play with this stuff, use gloves, ventilate, work with respirator, and minimize handling in any case. I know a guy with a recording studio and he loves the extended highs, what price are YOU willing to pay. He has staff members play with this stuff
..he just listens!

Oh yea, and do check out the Ampco tool site on the WEB, they have lots of info on BE, they use it in some tools for non-sparking non-magnetic needs. They don't like this stuff either and are trying to find other compounds that are safer.

"befacts.com" ...I'll stick with Aluminum thanks.

Anyone concerned about the nickel and cobalt in the rare earth magnet structures?

Especially when handling speakers and opening cabinets?

Lots more dangerous material in those structures.

Al-Ni-Co is dangerous? Well, since I have never handled the actual magnet of my compression drivers I guess it isnt a problem! But they sound good and are where people cannot touch them, so may I keep using them, please?
