hi i am looking to make a 15 inch subwoofer for my grade 10 electronics class we have cnc mills and such so it wont be a problem making the magnet holder. but i need a voice coil to go over my 2'' neo magnet ( K&J Magnetics - Products ). thanks

maybe you could buy a recone kit to get the the cone and coil attached.

You should upgrade the Neo to 2.5" so you could use Eminence recone kits. The easiest is to upgrade to 4" so you could use Peavy Black Widow recone kit with a basket.

The cheaper way to go is to use multiple small Neo with a 4" pole to use the BW recone kit.

That is a big scary magnet. Have you tried modeling with FEMM? There's no need for a neo magnet 1" thick, use steel to put the field where you need it.

Have you discussed this with anyone who understands the theory?
This product looks a poor choice for any normal speaker application and is not suited to a 2" VC.
