you don't,, you order a re-cone and re-cone the sub.. basically glue everything back together.. spider first then rubber surround around the cone.. then the cone to the basket..
speaking of spiders.. (the crawly kind) there are about 25 wolf spiders living above the entry to Cub Foods where I live.. I saw them for the first time today and was like OMFG!! those things can kill.. and in numbers living through it is reduced a great deal :S
