Just bought a joe rocket stain rk 101 helmet, Love it so far but the sticker right on the front of the helmet claims that it has a speaker cavity built in.. I have been studying this thing for about an hour, removed the padding and all and I don't see anything that looks like a speaker cavity.. anyone know what or where this thing is at?? thanks.

 

In my helmet it was the fact that there was removable pads by the ears... perhaps that is what they are refering to.
