Hi There
I realize that this is a very vague question, but I've got to try this. I was offered a pair of 4312 monitors for low money ~ 150$. The cabs are very scratched, but I know where they have lived their lives, and I suspect it to be only visual damage. The tweeters are not original, but maybe that is a good thing ... They look a bit like these ... but they have black domes and no grilles. Do you have any idea, what these tweeters may be. Again, knowing where they have lived, I would suspect the previous owners to have replaced the old tweeters with something from JBL.
The thing is, that the deal is now, and I will not have time to go see/hear them before a month from now.
Thanks in advance, I know it is a difficult one without a picture. The one above was the closest I got on google pictures when searching for jbl tweeter.
