Subwoofer Magnets
I was hoping that the folks around here who are knowledgable about subwoofer driver construction could tell me what type of magnets are being used in the modern high end subwoofers (Particularly the Stryke AV15 II).

Also, if they aren't using NdFeB, does anyone know why not?

Thanks,

Jason

They use ceramic magnets. Ceramic magnets are low-cost and effective, and certainly good enough for subwoofer use. If you are looking for a Neodymium-powered subwoofer, look at Madisound. They have a Sonicraft 12" driver with Aurasound NRT motor and they also carry Aurasound drivers, including a 3" woofer with 5" Xmax (that is 10mm peak to peak), an astounding amount of excursion for a 3". It also extends down to 80 Hz.
