B&W 802D tweeter replacement

See if you can get the non D version it should fit physically whether the crossover will be right is another story.  Good Luck sincerely but I do agree the $2,200 for those speakers is a great deal  perhaps you can sell them as is.

Thanks for the info--very helpful.  I totally agree that $2200 is a great deal for the speakers. And I got a bunch of other equipment to create a really good system. I'm grateful for that and don't want to sell it so don't really care about resale. But spending a couple of thousand bucks on audio equipment wasn't exactly in the family budget before all this gear rained down on me and it still isn't...so I just want to figure out my most sensible move is.   I really like the way it sounds just the way it is, actually, and am happy to own this equipment for the rest of my life.

And the diamond part of these tweeters is intact--it's just the mylar (or whatever it is) membrane that was poked out. It would be great if I could just find a way to fix them. And if not, maybe I'll try mechans very economical suggestion (thanks!).

Type in your model number for parts available and price, use the service manual link at top of page to figure out what you need to replace.
B&W’s are easy to repair, a lil patience. I do not see $1100 tweeters.

Thanks...if you search by part number (ZZ14265) you can see the tweeter for the 802D.  But I'll check with B&W to see if a less expensive tweeter from an Nautilus 802 (more like $150-$350) would work with the 802D enclosure.

If you use anything but the original Diamond tweeters, you will change the sound dramatically, and not necessarily for the better. The Nautilus tweets are aluminum and not even close to the Diamond ones, not to mention different crossover parts and values. Yes, those Diamond tweets are in the $1100 range, each.
