Hi, I have seen this problem. Scotch tape wont work, use duct tape or black electrical tape. Get maximum surface area of the tape on the cone and it should pull out. I dont think you will hear any difference sonically.
Tweeter cone on my B&W 805 Naut's is pushed in
I bought these used and the buyer didn't indicate that one of the tweeter cones (not the grill) was pushed in. It isn't broken or torn, but clearly somebody touched it and pushed it in. My question is how significant is this damage. The speakers sound good, but I can't imagine that this isn't causing some loss of performance.
