I won't swear to it. I just think I remember seeing it (the part about the plug) posted in there. With my old farts memory syndrome I might be wrong. LOL
BTW: is there really much difference in the port and chamber design of the EQ's vs. the RHS heads? In the pics they look nearly identical but you know how trying to pick out differences in pics on the net is. Only way to really tell is compare them side by side.
