The replacement bass drivers arrived. The seller mounted them on plywood boards with spacers so the rubber surrounds wouldn't be under pressure. Then he wedged them face to face, diagonally in a thick polystyrene box, which was then in a stout cardboard box. I think the delivery guy could have dropped them from the van and kicked them to the door and they would have been undamaged - but I'm glad he didn't. They measure well and play music through the x-over so will just have a light clean up before being installed. Many of these drivers have had after market cone treatments applied these look original and unmolested.
