Thanks airboss. I do believe that the magnets will not come off without removing the spider - and maybe the cone too. For that I'm going to wait. These may be usable to someone as they are.

If they turn out to be really useless duds then ripping those beautiful new cones off won't hurt so much.

I'm off to Dallas this morning to the Lone Star Audio Fest. Will be pounding the guests with an open baffle rig of Altec 605 and Eminence 18". Gonna be fun!
