I dont see any blue gunk under my mesh though. I didnt open it but i can see right down it with light. I'll see if I can take something with a macro lens.
EDIT: ok macro photos cant see behind screen.
I can definitely see right through to the inner vent at the right angle with my naked eye though.
There is nothing between mesh and driver cover in recent T2 units, you already have a version with slightly boosted bass compared to people who ordered it when it came out.
