The new Zu Soul has the 10" below the tweeter, which allows it to be a "shorter" design, @ 36" tall vs. 48". It has a 12" square bottom, and all sides have a slight angle as it goes up, so it has a trapazoid appearance.
They sound sweet, and have a little better (deeper extension) bottom end than the original Druids.
They are still in prototype stage, and price is rumored to be sub $2K.
