After a year of research I uncovered and compiled an interesting story from within the loudspeaker industry. You can download my manuscript here, http://www.s-m-audio.com/truth.zip

I wanted to contact you but I could not find your email address anywhere.
I am independent of any company; however, I do worship the god of math and physics.
You quoted me out of context.
Thanks for the proof read. I have made the corrections. You can view them here, http://www.s-m-audio.com/truth.zip .
Hey, and thanks for posting my discussion at the Usher website. Dr. Linkwitz has a link from his site too, http://www.linkwitzlab.com/links.htm#Transducers%20with%20Beryllium. If you had told me earlier, it would have saved me a bunch of work.
Anyway, I am so pleased that folks now understand that the Usher Be-XXX are really Ti-XXX but with a close color match to Truextent (acoustic grade beryllium). In 2004 this coloring was identified as paint, http://www.electrofusionproducts.com/userfiles/China_Be_Domes_Report.pdf . Can you tell or another reader tell me how a material that is 88.47% Ti and 6075 parts per million Be can have the steel gray color of Be other than by painting? I am just not comfortable with that.
Mike Klasco also discussed Bogusium in Voice Coil, http://www.audioxpress.com/magsdirx/voxcoil/addenda/media/BogusBeryllium.pdf . Both the testing and article were about Usher's supplier, Sonic Electronics.
My identification of the psychoacoustic Be placebo is a topic of research and has merit. How else can one explain the preference for loudspeakers?
