Help lancer 33 jbl le8t two different speakers

[Adamacc10]

I purchased a nice set of lancer 33. After purchase I noticed that one had a sprayed black ring on front and one was aluminum. So I toke then it and the black front one is all aluminum on back and has no sticker on it. The other is a 16 ohm le8t. Could they come from the factory like this or does anyone have an opinion on how this could happen?

Also the wiring is different in both cabinets the older speaker on the right. I say older because of the screw on wire connectors has a thinner wire.

Serial numbers on the cabinet are 10038 and 10049
