@purr1n you're measuring the modded version with the super soft pleather pads right? Not the leather pads? the leather pad version is not the finished mod. the finished mod on the V1 and V2 use the soft pleather pads. And if you can would you mind posting the distortion figures for the stock HE6SEv2? I put a huge amount of time and effort into making the cup inert and super rigid right where the drivers screw into the sup, so it's attached to a very solid base, which should help and I'd love to see if it is or not. Thanks for the measurements!
