No need to shorten you post Bila. It was spot on. Like everything else, you have a handful of manufactures for most items. Take Cd's. There's a few that make CD's and all the buyers pay to have their name inked on them. Stryrofoam is styrofoam. It can finger say finger lickin good or johnny's good eats, same stuff. I agree that I doubt they have the manufacturing facilities to assemble the drivers on site but the materials they choose to assemble them to give them the Grado sound is what makes them appealing to buyers.
When my dad purchased a 76 stingray Vette back in the 80's it plain hauled. Below the shifter bezel it had a tag that stated 8:1 compression. My friends were building 9:1 trying to achieve acceleration but it did not have the same punch. But you know what...It had nothing to do with the quartrajunk 4 barrel steel intake manifold 8:1 chevy 350 that made it haul....It was everything from front to back. That means using the right gear ratio's in the trans to selecting the correct differential ratio's to achieve acceleration and top speed.
So yeah, Grado bought the drivers from vendor a or b, but assembled them in a fashion that produced a unique sound that has many craving more. Heck the drivers look the same in My Bose OE's
It's all in the touch......
The question of whether Grado makes its own drivers is a sensitive one. It's a debate that brings out some of the angriest replies I've seen on HeadFi. The official word from Grado is that the drivers are made in-house, so - at least to some Grado fans - to suggest otherwise is to call somebody a liar. You don't have to live in Texas to know "them's fightin' words."
