STOP!!!

Before you remove that large bolt in the back of the pole piece, remove the screws on the cone surround, the screw in the center of the spider, and remove the cone completely (unsolder the voice coil leads once the cone is loose)!

Once the speaker cone is removed, you may proceed to remove the large nut from the pole piece in back.

Don't ask how I learned the right way to do this.
