Sorry to bother but do the Turbulent X Drivers have the same dimensions as the as the Grado Prestige Models with the "i" or the Alessandro MS1i? Reason I'm asking is because I'm trying to get a wood turner to make me some custom wooden cups out of the dimensions of the SR225i as I am having trouble finding accurate dimensions for the mushroom cups on google.
Side note - does anyone have any extra Grado Plastic Cups/Housing "i" for the Prestige models? I'm deathly afraid of messing up both the drivers and the cups during the removal process. Please PM if you have an extra set.
According to Luke at Turbulent Labs, the exact measurement for press fitting a magnum driver is 45.6mm and a depth of 9mm. This should be the same for any grado driver as well. I find it easiest to get it to 45mm and hand sand to fit. Hope that helps
