Interesting article on the Valencia.

Is there an easy way to tell the difference between an "Iconic" Valencia and 846A model? What are the differences? From what I've researched, the horns/drivers appear to be identical (806A driver, 811B horn, 416Z 15 in woofer). I've seen the "Iconic" logo on the back of some Valencia's, but had heard that the inclusion of the label did not necessarily indicate the speaker was an "Iconic" model...
