Hi guys, I would like to ask for your advice. I recently got a pair of Altec 879A with 15" 420biflex drivers, which I enjoy. However, one of the HF tweeters is broken and I don't want to go for the phenolic tweeter clone available. For me, they sound too harsh and not very defined.
I'm not sure about which tweeter to choose to fit to the 420, which should have a sensitivity of 97db/W.


Do you have any recommendations?

Thank you!
Frank
