@larry5729 , on Monday (tomorrow) when they are back in the shop, they will check to see if they have a D2 series tweeter that they can send to me. Otherwise, they will have to order one for me from B&W. We'll see how it turns out. But yeah considering the comments, I think it might be worth picking up a couple spare tweeters myself, despite the very high cost. At least I have a working pair of 802's.
My problem is I have a local buyer interested in my old 803's, which now are down one tweeter as that tweeter is now tweeting happily in my 802's. I need to decide whether to move the tweeter back to my 803's to facilitate the immediate sale, an potentially be without any speakers for many months while I'm waiting for a new tweeter to arrive from B&W. As I'm typing this, I don't think I will do that; I want my new speakers to be functional...
I am hoping the shop will have a spare tweeter, in perfect working condition, that they can send to me.
