Thanks but not sure I follow your point. I know that the WBT spades or pins as the case may be are brass (gold plated for teh pins); I am referring to the cable parts that go from the cross over to the WBT spades/ pins. The x-over links the ribbon part to the cables that can be connected to the speaker terminals. The 5" cable lenghts connecting to the speaker is what I am talking about. The ribbon part cannot be verified without breaking open the x-over..
