Also do you have any other Pi logos I can put on my webpage?..If so please e-mail them to me.
Thanks
James

I chose the name because every formula that concerns itself with rotational velocity uses Pi, so practically every fomula required to design a loudspeaker uses it too. From the angular coverage to reactive formulas, Pi is everywhere.

And there's one other third thing. The Cyrillic and Greek alphabets have the character - π - which is first letter of my last name when spelled with that character set.

By the way, the logo used today has remained exactly the same since 1977. I used to hand paint them with a stencil, and I still have the original stencils. A few were made with sterling silver poured into a mold, with three risers being used for mounting legs. But for several years, I've used the vinyl decal instead.
