The parthenon is sort of old news; I'm not sure why you wanted to bring back a thread that's been dead for 4 months to point out an old driver that will never make production.When it comes to SPEAKER APPLICATIONS a temporary rise in heat can cause a temporary decrease of magnetic energy. Ceramic magnets seem to perform better than neodymium when exposed to heat.Google search "adire parthenon"... The creator of it (parthenon with a 24"x 24" baffle) claimed to move as much air as 10 18" subs, accurately.
There have been several neo subwoofers/woofers that have actually made production if you're trying to point out the fact neodymium is a viable motor material. Some even using Dan Wiggin's (Adire mastermind) xbl^2 tech.
