It's my first message here. I do'nt speak a very good english, so excuse me.
I've got a pair of used 2404 and one of them is a little more powerfull than the other and when I had a look at the diaphragms, I had to see that they were not the same. It's maybie my probleme. So I would like to change those diaphragms but original JBL diaphragm are too expensive and I saw that a lot of shop are selling aftermaket diaphragm on ebay. BUT what to buy ? Is there a good thing to buy ? I can see that there are aluminium or titanium diaphragm, but what to buy ? Is there a real difference between the original ones and the aftermarket ones ? I use those 2404 as super tweeters on my S3100, so only hifi use.
thanx if you could help me
here is a picture of my diaphragms
