Sonus Faber repair?

I'm in California. I recently acquired a set of Sonus Fabers with a blown driver. Any idea who is the best to sent them to for repair?

CA (Bay Area) ideal, but will ship wherever!
sumiko audio, the u.s distributor for sonus faber, is located in berkeley.

If they can't fix them, I bet they can head you in the right direction.
Where else than Sumiko Audio, the North American distributor for SF. Check I believe it is in CA also.
