I have a pair of tweeters with the above part code. Additionally, they have 'C5 Wave' ink stamped on them and another number almost too faint to read. As far as I can tell, it is '633TND'. They are both in excellent condition having only been used as replacement tweeters in a pair of Yamaha NS10M studio monitors.
I'm presuming they are JBL tweeters from the little bit of info I can find floating around on the web.
I'm stripping the NS10Ms for spares and was just curious as to the tweeters saleability/worth?
Can someone help. Any information would be appreciated.
