This is showing the process of me redesigning this sub. I had to do this because fits in the enclosure way better, the old one didn't fit because the cutout diameter was 1/4" too wide and the tape holding the rubber bands that I used for a spider came loose and the surround had air leaks in it. This one is better designed. The surround is taller so it can handle more excursion.
If someone wants make one, these are the materials I used but you can try different materials if you want.
Cone and basket - foam board(very stiff and very light)
surround - duct tape
spider - file folder
voice coil bobbin - paper towel roll
voice coil wire - 26AWG enamel coated wire(from Radio Shack)
