Here's the place Madisound recommends for Dunlavy repair, Meniscus Audio in Grand Rapids MI. They replaced rubber surrounds on two 10" woofers for me, fast turn around time and reasonably priced.
As far as I can tell the rubber surrounds don't deteriorate noticeably over time. My surrounds were damaged by "die Katzen". Both speakers are now covered when I'm not listening. 8^)
PS: I've mentioned this on several Dunlavy threads, the IVA is superior to the IV. I've owned both. So, if you're serious, definitely look for the IVA.
