Does anyone know why the double speed thing works? It's very effective for me too, I usually keep video at 1.5x often will have to jump it up to 2x to be able to handle it
I'm guessing it's the lube slightly leaking out. I mean I wouldn't eat it. It's probably not going to short circuit anything and damage the board. It would be a foolish choice to fill keys with conductive lubricant.
Just remember crossover is hardly ever used now. Straight is almost always what you need for typical use.
