Dynaudio 24W100 recone/refoam?

[engr_dave]

I have four 24W100s in a pair of Dynaudio "Myrage" WMTMW towers that have succumbed to dreaded "foam rot". I see several online sellers with repair kits such as speakerbits, reconingspeakers, and ebay. How do I know these won't affect the T/S parameters? I'd feel better getting recones from Dynaudio, but it doesn't look like they offer that service. hifisound.de sells "exchange" drivers [spendy] but are these simply ones that they recone/refoam?

What is the best way to be assured of OEM quality?

Two answers, assuming that after all this time you have not found an answer.

These guys claim OEM parts:

In reality a foam surround contributes vastly less to the compliance than the spider, and the variation between an OEM and 3rd party foam surround will be swamped in the driver to driver variation anyway.

Installing surrounds isn't hard, but does require patience and care. I did a friend's 20w54 drivers with generic surrounds a while ago and they worked out perfectly.
