Hello Everyone
First my apologies that I start right off the bat with this inquiry but I have exhausted the limits of my googling abilities.
In the early 90's the Importer of JBL to the Netherlands gave me 2 bullet tweeters. He told me they where JBL's. They are very very good tweeters and I have used them in my studio for years. Having dismantled the studio I realized there where no markings on the tweeters that made it out to be JBL's. The design looks very JBL to me. But I can not find any picture or reference to these tweeters by JBL or any of the other major professional manufacturers. So I attach these pictures hoping someone will know what they are.
The magnets are very large in comparison to the cone.
Kind Regards
