Just tried to refoam a set of Allison Five 8-inch woofers and came up non-working. I used the shim method, but noticed that there was very littly clearance for the shims, and that it seemed to not have equal clearance all the way around, but it's so minimal, it's hard to tell. I don't know if this is because the voice coil is deteriorated shapewise or if the speakers were just made that way. The first woofer came out rubbing badly, so I tried very diligently to get the second one dead center. It plays very nicely, but buzzes once the volume gets above medium at all.

Is this a common problem with these speakers? I noticed that there's a pair of these on eBay now that says "needs a re-cone."

How special are these drivers? If I put a nice pair of vifa 92 db 8-inch woofers in there, will I be screwing things up obscenely? Who'd notice?

TIA for any advice or sympathy.
