Tweeter for ADS L620's

These should be all over Ebay, not that uncommon a tweeter. And always try Madisound. And if you haven't tried, you might try ADS, I would not be surprised if they had a few pair, that was a popular loudspeaker and that tweeter was used in a lot of prduct.

If I am not mistaken, this tweeter while marked as ADS in ADS speakers is in reality a Peerless 810665 which is available at Madisound who should be able to confirm this factually. Madisound referred to this tweeter as an "evergreen" among dome tweeters because of its widespread use my many quality speaker manufacturers in its early inception.

I own quite a few ADS speakers, and I can tell you ADS is of no help. Contact Cosmophonic Sound in NY, as they now handle all service work for ADS. Contact Tom. Sorry, I don't have their number handy where I can get to it at the moment.
