B&W 802D tweeter replacement

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!).

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.

I own both 804 Nautilus and 803D speakers. Both have exactly the same FST midrange (kevlar) driver, but different tweeters. I can tell you the Nautilus tweeter is dimensionally quite different than the diamond tweeter, and I don't think the Nautilus tweeter will mount properly on the 803D. They also have different sensitivities so you would have to alter the resistor in series with the tweeter, and maybe the coupling cap. 

Sound wise, I liked the Nautilus tweeter quite a bit. I don't think they are as far apart as some would have you believe. But all that is mute if you cannot mount them on the top.

One thing you might look into is whether the separate driver parts are available instead of the whole tweeter. I think they might be, as the exploded view in the technical manual shows individual parts. No sense buying the outer casing if yours is fine.
