I'm NOT an ace.... but I'm willing to learn. The instructions that came with the foam and glue mentioned nothing about the coil, etc. So, I have the new foam on and I'm guessing I need to take it back off, order some more and start over?

If the voice coil is rubbing, it should be possible to feel that when you press (gently end evenly) on the cone. Other things that can cause problems sometimes would be a gap in the glue holding the surround, or a wire slapping the cone from inside the cabinet. If it is the voice coil rubbing, yes, you can usually order another refoam kit and fix it.

Frank,
What Don C was saying was good advice. Before ripping apart your refoam job, eliminate the other potential and simpler causes first.
You haven't said yet whether you can actually feel a rub when you gently push down on the cone (no power on when doing it). Probably best to have the woofer out and laying magnet down on a table or the floor so you can better feel that you are pushing evenly or squarely.
I kind of wonder if it is VC rub when you say the vibration only begins at high power levels. Anyone else with a feel for this? Would a VC rub not be evident even at low levels?
Are these a ported speaker ? If not, perhaps the box is not sealed well and the woofer is not as controlloed as it should be. IS there a gasket ( in good shape) between the woofer and baffle board?
Keep us posted on your progress. We all learn from little problems like this. Never know when it may happen to any of us .

I don't feel a rub when mounted in the cabinet. I'll pull them this weekend and see how laying them flat on the table works.
