I read with interest the post by StPete Cooling re repairing a buzz coming from Klipsch ProMedia 2.1 BT Speakers. I bought a ProMedia on 12/4/16 and used it for only a few months before my schedule changed. In March, I unplugged the subwoofer and custom desktop and they both sat, unused, for 1.5 years. (Nobody uses my office equipment.) After replacing our wired home phone with a VOIP phone system recently, we found the subwoofer interfered with VOIP operation even if it wasn't plugged in. Called party hears nothing when we place calls ... no voice, no static, no beeps, no hum, no buzz. Today, we plugged in the subwoofer in an attempt to move equipment around to solve phone problem. For the first time, we heard constant static. This infuriated me since the ProMedia had only been used maybe 5-10 hrs per week for 3 months. And whenever a new window displayed on the screen, there was static over static. I moved the speakers around, checked connections and organized the wires. No change. I kept moving stuff on top and below my desk. Voila! The static turned into a buzz. That's improvement! I switched the speakers and moved wires around, but the buzz continued. But when the speaker was lying flat in my hand, the buzz became softer. I kept turning the speaker around in all directions for, maybe, 20 seconds and, all of a sudden, the buzz disappeared. Totally. The noise wasn't made worse or better by turning the volume knob. All I know is that I don't have to bring the system into a local shop that repairs premium equipment like Thiel or restores vintage pieces like Tandberg. Next time, I'll pick speakers with no sub given the issues with Klipsch equipment noted here. StPete Cooling: I've kept your instructions and this URL in case my repair shop needs them later!
