Monitor Speaker Repair Sorry I don't post on here hardly at all but could do with a bit of help. I don't really fancy driving down to M-Audio repairs in West Yorkshire when I could get the job done a lot closer to home. Does anybody know any technicians based locally who could fix one of my monitors? I have tried ringing Sound Control and Sounds Live but can't seem to get through to a human. The tweeter has developed a high pitch whine on signal input, regardless of what it is plugged into and with what cable. It's an M-Audio BX8. Cheers
