WCA Rusty

Hey Rusty, 

I see you're THE DC guy. I was wondering if you could help me with measurements on a level 4 sub? I don't know of any dealers that would have them in stock for me to go look at in person, so i'm scouring the internet trying to find an answer. Question is: what is the height the sub sticks out above the face of the box? I know the ring is roughly 3/4" but what does the surround stick up past that? 

Thanks!
