I replaced the salon 2 with the usher be20 dmd. The salon2 tweeter is pretty special other than that I preferred the usher overall. Idk if the dmd mid is worth it but if I still had the speakers I’m sure I would upgrade them.
I was not able to find diamond tweeter enywhere. So I will first
try to tame beryllum tweeter with extra resistors. I think that Usher
strategy is to sell the same speakers with new drivers instead to
sell drivers as separates. The difference in price is +$5000.
''Beryllium'' was a kind of ''fake beryllium'' so this may also be the
case with ''diamond'' drivers. Besides there was no consensu among
members in the ''old discussion'' reg. the tweeter about the question
which was better sounding.
