That reminds me, I need to come up with a way to reproduce a voice coil, less wire to deal with but I am still thinking about what to use to make a form out of. The reason is that I have several speakers where the voice coils use a paper form and the form has a kink in it that rubs on the pole piece, some are also torn. Getting back to removing a pressed in pole piece a hydraulic press like a mechanic or machine shop would have would work, it was how thet installed it in the first place only you are doing the reverse. I never though of a gear puller to remove it, I don't think I would try that to get it back in though.
