This came from a single AR3a speaker, with an irreparable cabinet. Amazingly, this tweeter has survived over the years and the suspension is still soft and pliable and the output is as good as new. Nice long leads on this one as well. I know a thing or two about these tweeters, since I perform full rebuilds on them when needed, but this one is still 100%, Not requiring A rebuild. What I did do is replace the electrical tape that secures the leads to the unit, since the original tape was losing its adhesion.
Typical flexing of the flange as the pictures show, but will seal up nicely with mortite, original sealer or foam seal.
