Next was to take out the screw holding the spider on. Here sometimes you have to be careful if the spider is made out of cardboard, which this one was.
Then you can lift the entire cone out at this point. Then according to the voice coil size, you either remove all the old paper from the voice coil, or leave some sourrounding it, to match the cone opening.
The new cone I selected turned out to be a higher profile than needed, but the voice coil opening was perfect. So I removed all the paper from the voice coil. Next I drilled a hole in my bench top, where I could stick a pencil in, and put the point of it thru the spider opening, then set the new cone over the voice coil assembly, centered it, and glued. Left sit overnight.
