So, I have a pair of Airmotiv 5 speakers I picked up a couple of years ago (they were new-old stock) and they have been great, until today. I don’t generally leave them on, but I turned them on today, lisntened to some songs, and the left them on. I started hearing loud static emitting from one speaker, randomly, even with the source disconnected. It will come and go... from silent to cracking. Touching the speaker seems to have no effect, and adjusting the shelving EQ makes no difference. It can be silent for 30 minutes, or emit static in two second bursts for a few minutes. I keep the volume at max as I use an Emitiva Control Freak to adjust the volume from a turntable/preamp, the only source I have connected. Anyone have any ideas? Indoor relative humidity is around 17%, which is fairly dry, if that makes any difference. There were several months when I left them on full time before deciding I don’t use them often enough so I leave them off now. They are powered though a decent APC surge-arrest power bar, so I don’t think it’s an issue with dirty power, and I don’t have anything on the circuit that might be generating any noise.
Could be almost anything. Likely things, cold solder joint, bad electrolytic capacitor, power transistor or driver transistor. That is just a starting guess. Best bet? Contact Emotiva Support to see what they say and base your decision on what they tell you. I have the Airmotiv 6s and they are silent as the night is black.
