Hi all

I feel sad to read that M choose to use the toxic substance of Beryllium in its new tweeters. "The commercial use of beryllium presents technical challenges due to the toxicity (especially by inhalation) of beryllium-containing dusts. Beryllium is corrosive to tissue, and can cause a chronic life-threatening allergic disease called berylliosis in some people. The element is not known to be necessary or useful for either plant or animal life." Source wikipedia

The toxicity source is a verified source. I really would hear what M has to say about choosing this material. I am fully aware of physical benefits of this material in this situation, but is our sound so important that we have to use very dangerous substances?

Best regards, Per Nilsson
