Boogie says they have got Fillmore speakers, but at the back of the book says C90?

The "Fillmore" project has been going on for years but i've never seen or even heard of any actually in existence. A couple years ago i asked someone in customer service about them & was told that the intent was to duplicate the C90 as closely as possible but that they were still working on it.
