You are correct Ron, but your pic shows an 806 body which appears to be a model 23746 HF driver from a 9849 monitor. It should have a new style back cover, a 23744 "light" phragm, and a steel annular slit phase plug.

As far as i know those drivers are unique and only found in the 9849's, fine sounding driver and best of the 806's IMO.
