Greg's main midrange compression driver supplier for a while now has been BMS (the 4592ND, to be specific), but I don't know whether he's made any brand changes here. I doubt it. The BMS is a great driver for sure, and its polyester ring radiator diaphragm should last decades, I suppose, while being an SPL rocket. The remaining units, woofers and tweeter compression drivers, to my knowledge are still from Faital - decent quality pro drivers. Being pro drivers alone is a big win with regard to durability and overall longevity, and I could see them lasting decades as well.
As to Greg's claim of "one hundred year speakers," I don't know. Seems a bit on the puffed-up side of the fence, if you ask me. He's a fine woodworker, from what I can assess, but heirloom quality? Who knows.
... I would like to know fwiw where Greg sources the drivers. There is a reference both on Greg's site and repeated again in the review that these are "one hundred year speakers". Is that referencing the cabinet or the drivers?
