Tweeter cone on my B&W 805 Naut's is pushed in

Just get a vacuum cleaner, attach the extension tube, then place the opening of the tube around the damaged tweeter's cone. Turn on vacuum. It should suck the cone back in shape.

Good luck,

The Nautilus tweeters run around $100 for the 805's as this is what the dealer quoted me.

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.

Fast forward to 2019.  My Nautilas B&W 803 "aquired" such a dent in the tweeter metal dome.  Scotch tape did not work.  Packing tape did not work.  Duct tape WORKED!!!  Saved me $145.00 for a new tweeter.

Took nine or ten snappy pulls but 100% of the dent came out.  Has some minor creases remaining but with the tweeter grill back on, hard to tell unless your look closely.

Boy...that would bother me.   There are fixes, but all are compromised.  I'd get a new tweeter.....you might want to ask B&W if they can recone/repair yours.  I know Vandersteen does on their products.
