What has this Ouverture picture got to do with the topic?

Bad surround? Or the dustcap?

Completely out of center? Is that what I see Eugene?

Just had a quick view Steve and I already saw this thread but I can't see any shimming. Just the battery method, or is that shimming? Now I'm really confused

Martin, I've seen your pictures an they look worse! What do you think these kind of people would handle when using the shimming method. They should keep their hands off refoaming at all!

Finally Martin, you're back! I'm convinced, because of all these good advises that shimming is a need to do refoaming the right and precise way. However, and I have not done this shimming method before, I wonder if this is really necessary for small diameters like CX50/100 drivers? Other thing is, would people with no experience at all take

All drivers I have refoamed mostly CX50/100 are done with the shimless method and never had any complaints what so ever!
