Diamond vs Aluminum tweeters for B&W 800 series

@gfguimaraes 

I'm sure that it would be fine.

shattered? usually you burn out the coil, what do you mean shattered?

I would buy a new pair and have 1 working spare.

is it possible the bad tweeter can be repaired? have you looked into that?

my active horn tweeters and horn midrange drivers were made in 1958, impregnated linen, essentially indestructible. I did burn out a coil blasting Iron Butterfly, I found someone who replaced the coil way back then.

The B&W diamond tweeter is fragile material that can literally shatter if something hits it unlike a aluminum dome that will dent. 

oh yeah, there’s some Beryllium tweeters out there, that is my preferred cartridge cantilever material, lightest/stiffest .... I just acquired 2 vintage used and 1 NOS, but don’t look at beryllium when thinking unhappy thoughts, it shatters easily, I broke my original Shure V15VxMR’s beryllium cantilever, dropped it 1". Unhappy thoughts came fast.

Theory: I believe in matched sets, keeping a working spare. I’m 76, ears far from normal, so it’s more ’good practice’ than needed but who knows when current stock is slightly different, or testing methods slightly different.

It's a long shot, but before buying anything I would contact Bill at Millersound.  He is a premier speaker repair person.

All he can say is he doesn't repair diamond tweeters.  He does list B&W as a brand they do service.  From experience I will mention his repair quality and prices are unbelievable.
