Arran certainly has much more experience than I do Greg. Indeed the cone may be separated from the voice coil and hard to tell from the pictures. A great idea to carefully remove the dust cover and review that situation. Spacers should work well around it if you need to re-attach the cone with some adhesive to the voice coil. I would not try to manipulate the cone manually with it dry. Look carefully at the spider as well as suggested, if loose not bad to re-attach, nasty if it is broken.
