Orange County Speaker Repair

I learned today that Orange County Speaker Repair no longer repairs speakers, however their head speaker repair technician has formed his own company called Speaker Repair Pros.

Thankfully, I don't have a present need, but for future reference, besides this new (old) resource, what other speaker repair shops do you know of in both the Southern and Northern California areas that do reputable work?

TIA,
