Just looked it up and a dodecahedron has 12 faces. http://en.wikipedia.org/wiki/Dodecahedron

By the photos on the ED website it looks like there are two faces that don't have drivers. So this sub seems to have 10 drivers. I think that WAF for this sub is probably impossible for 99% of all married home theater enthusiasts that even have the budget for a $5000 sub. Heck, I don't think that I would want such a thing if money were no issue.
