This is a brand new coil. It has never seen power. I had to recone a brand new subwoofer because it was the wrong configuration. The surround is in good condition and the spider is usable but not perfect. It separated in a couple of places when I was removing it. Extra glue is needed I'm sure.
All but the dustcap is reusable. You would have to cut out the dustcap to shim in coil when installing this drop in, and get another dust cap. But the whole thing can be salvaged.
