I have 4 of these drivers, brand new never used. Got them on E-bay a number of years ago. They look and test perfect but the rims are badly cracked and dented. The solid seat past the outer perimeter where the gasket goes is still perfect so still usable. The damaged part could either be routed off, or they could be used out of sight. I was thinking I'd like to try my hand at a transmission line project. Thoughts?
