I've never done a refoam before but I realize
it's not rocket science but there's probably
a learning curve. I won't have the option of do a trial run.


These drivers come out of a pair of Infinity Crescendos,
and the plastic dust caps seem well bonded to the cone.
I'd much prefer to shim the cone before bonding the foams,
but I don't know if the dust caps can be removed somehow
from the cones without damaging them.

Any advice appreciated.

This one in about the Infinity Crescendo CS3007 model.
