What driver does Linn use in the Sizmik subwoofer?


Does anyone know what driver (10 inch) Linn uses in their Sizmik subwoofer?
I acquired a Sizmik amp and I am looking for the driver that they use so I can build my own subwoofer. Do they make it themselves? I called Linn and they
are asking way too much for the 10 inch driver.
Thanks for any help.

How much are they asking? I know that when I was looking around to build a subwoofer, the really good drivers were $200+. At least, the ones that had enough xmax and fs for the job I was going to do.
