In Eminence drivers, the mesh is just pressed in, and can be easily pried out.
Check to see that the ID of the center pole has constant diameter throughout. Sometimes, when the back plate is pressed on, it compresses the center pole piece and makes it out of round. You want a constant diameter to maximize the area of contact between cooling plug and center pole. If it is not round and uniform, machine it to make it so.
You can use a hone, but even a drill press will suffice. Naturally, this step is easiest before assembly (or during a recone) because the magnet will capture the debris. That's OK unless if it doesn't get into the gap. If debris does get into the gap, it is easy to clean if the voice coil isn't there, but practically impossible if it is.
