I'm not sure, but I found out from Bill Fitzmaurice's board, he's modified at lot of his speaker designs to handle ferrite magnents using Eminence lab's, because of Neo prices are on the rise, and he does't like using lab's because of the to low of fs for his designs. Supposedly the Neo price's started at the beging of April this year. I wouldn't be suprised if the chineese are buying a lot since it's a rare earth metal. I haven't checked out the stock markets for them myself, but you might want to check it out with Eminence since your a dealer for them and see what they have to say.
Here's a reply from Leland Crooks, from one of Bill F.'s board:
"I just got off the phone with eminence. They and the rest of the industry are pricing Neo drivers on a 24hr basis only. Prices are spiking right now, could as much as double. The Chinese cut exports by 60%, and raised the tariff. Most of the increase is due to the export restriction. It will take a couple of years for local mines to get into production.
I've had to kill all my sales of neo's until I get some new info. They are scrambling to put together pricing as I type. Right now it looks like anywhere from a 30 to 100% increase depending on the driver."
