From what I have seen of the factory online, they veneer the sheet of MDF then cut reliefs with a cnc router. The speaker is then folded into its final shape and glued. I suspect the veneer was damaged in some way so they flipped it over and put more veneer on the other side to salvage the sheet of MDF.
As for the driver, what I do is use a wood screw that is larger than the mounting hole and turn it in so it grabs the metal surround , and then leverage it out with a large metal table spoon. The drivers are tough, I have built speakers with Axiom drivers and they can take it.
