B&W 805s tweeters replaced with diamonds

The price difference between the 805s, and the 805d is double! The 805s was $2,500. and the new 805d is $5,000!!!
So those tweets are VERY expensive!
I would bet they cost like $800. each from B&W IF you could get ahould of a pair.
(and then you would still have a bastardizedspeaker, which would not be resellable for anywhere near what you put in.
I would also think they put in a better woofer.. Bye the way.
(I owned 805s and traded them in for my Magnepan 3.6s.also $5,000. I would never have traded in for a pair of 805d at the $5,000 price tag.. )

Even if the woofers were the same (I'm sure they are not), the tweeters are two completely different tweeters. Which means the crossovers need to be redesigned (not tweaked, redesigned). It may "work" but I am positive you won't be in the same league as the actual 805d. FWIW, I would suspect that $800 each won't buy you a pair of diamond tweeters. I know that companies like accuton want about $5800 for the pair. B&W's are not that expensive, but I'm sure they are quite pricey.

Elizabeth has definitely illuminated a more preferable path.
