Funny you should ask, as I just got off the phone with a potential supplier. I think I probably told you that CTS is negotiating to sell the tooling for the tweeters, so that's all up in the air. Right now, I am planning to sample tweeters from a new supplier and if they are of good quality and can maintain QC, then I'll continue to use them. We have plenty of CTS KSN1038's in inventory, so I hope we have enough to get through the transition period.Two other options I've considered are the Eminence APT80 and the Vifa MG27T. But I like the little one π's and two π's just as they are - They've been virtually unchanged for 25 years. I guess I'm just kind of attached to 'em, so I'm hoping that the KSN1038 vendor transition is smooth.
