Hi all. I have a Yamaha RX-v683 receiver with Kef Q15.2 speakers for my front L/R. For months, my right front speaker has not been receiving audio to the tweeter. I tried troubleshooting by switching the front speakers, and now I have the problem in both fronts. The audio sounds thin, and there is no movement in the speakers when I touch them. Center, surrounds, and Zone 2 speakers are all functioning normally. I have tried recalibrating with YPAO, restoring factory settings, and unplugging everything and replugging. I have also tested the front speakers on another Yamaha receiver and they work perfectly. I have no idea what else to try. Any thoughts? Thanks in advance.

If the KEF speakers work fine with another AVR, then the Yamaha is probably ready for retirement. Which is curious, because Yamaha gear is typically very reliable.

Thanks, Wayne. Since I wrote this, I plugged in a Focal Dome and it passed audio clear as day, so I guess the receiver works, just not with the Kefs. Why the Yamaha would decide all-of-a-sudden to not like these Kef speakers is far beyond me. My Yamaha RX-v520 still likes them just fine. Weird...

Weird indeed. Could it be related to radio interference?

Trial and error with rolling part of the speaker cord into a coil. Or add ferrite cores at the amp side or speaker side or both. If no success, try them on the signal interconnects or on the power cable (where a line filter may be better). The point is to add some high frequency losses on wiring that could be an antenna to reduce impact of whatever interference may prevail in your listening area.
