Thanks for that, and I agree but this is a specific part of the speaker that needs to move because it's a new technology that I can't explain due to an NDA. It's the outer rim that I need to extend very high, pulling the rim itself up and then back down to it's original upside down shape, while staying put on the very very outer edge the whole animation. I think it would use a soft body tag on that though. The cone would need to be pinned to the very bottom of the upside down U shape of the rim, while the outside edge would remain pinned to the speaker frame. Then the cone goes way up and takes that inner edge with it, about 2/3 of the way up to the apex of the upside down U. Then back down. And it only needs to happen once
