I also have a pair of Nines with no sound. If anyone knows where to find a repair manual or just schematics, I would be very grateful.
These were bought as Refurbs. When they went down after a day I was refunded and told to dispose of them. Seems silly to get rid of brand new speakers. I may even add binding posts and use them with an external amp until someone comes up with schematics or a troubleshooting guide.
Maybe I should start a Nines repair thread.
