I am sure there are executives at M that are aware of the human health risk posed by Beryllium. Any manufacturer wishing to shop their wares in the EU is required to assess the content of hazardous materials in their products and disclose those risks to the government.

I am likewise sure that the tweeter manufacturer has taken extreme precautions to protect their employees from exposure to this very light and toxic metal.

As with all hazardous materials, the danger to an individual or a population is the effect the material can have on you, how large the dose you receive is for a one time event or over an extended period of time to have that effect, and, most importantly, the ability of the material to be transported into the body.

Beryllium is a solid metal that has no mobility unless it is disturbed. Even if you picked up the metal and ate it, it would likely pass through without getting into your bloodstream. The risk with Beryllium is inhalation of its dust and having it accumulate in your lungs. This is very unlikely in a consumer product just like for any metal (except mercury but that's a whole different topic).

We are all at much more risk of exposure to toxic materials by pumping our own gasoline, whether the gas station has vapor collection or not. Benzene, toluene, xylene and ethyl benzene are organic liquids that vaporize quite readily and can easily transport themselves into our bodies and be absorbed into our tissues.

Per, I respect your opinion and I'm not trying to diminish your position, but there is a lot more involved than the fact that a toxic substance is used to produce a product.
