I asked Josh at madisound about the Graphenes, said they were slow sellers, wonder why?

IMHO the Excel Magnesius's have low ~~87db ~~ sens, so its doubtful a special nano coating is going to make any ~~wow~~ factor.
Note in the descript
**nano coating higher dampening factor**
Thing is the E and EX magnesium are already **damp** with zero resonances in the lower ,,in fact throughout the entire fq range of the driver.
IMHO magnesium is the ideal and best choice in cones for a midwoofer.
The one characterist that defines how magnesium performs is ~~Neutrality~~
= No coloration, no muddyiness.
Unlike paper type cones, which suffer from both flaws.
Seas does have a new paper mix cone the Nextel which Troels loves in his designs, but then its not really paper as its heavy coated so as to completely dampen the paper flaws.
Some labs employ carbon fiber, which to me is like the plastic type cones from the 1980's. Sonus faber uses the Carbon Fiber in its 2 way @ 16G's.
The CF will offer a tighter low end, but how does the upper bass past 100hz sound through the entire midrange?
This ism what i would like to know.
Stick with Magnesium, as its the best compromise of any midwoofer cone material.
