Very lucky, indeed!
Not as lucky as I was, when Russ, aka Budman, made a pair available to me to complete a gift to my son. He's grateful everyday for his Heresy and Harman Kardon 430 system. Thanks Russ. I wish I could help you with the 4R crossover you seek.
If I were you, I'd buy the badges that are still available directly from Klipsch.
Thanks, I'll try to contact Klipsch, but since I'm in Europe, I have very low hope.
Your speakers look stunning, I thought about refinishing mine, too.
