I need some help as this is driving me crazy. I have two klipsch r-115sw subs and both were purchased new within the last 12 months. Over the weekend i noticed that both are humming when i turn everything off. I listened more closely and they also buzz/humm if the system is on and there is no bass coming out. They might have been doing this since new and I never realized it or it could be something new. I have read all about the infamous ground loop and have tried all the suggestions for that. I unplugged the coax cable coming in from outside for our cable service. I have tried using different surge protectors and power strips. I have plugged the subs into different outlets along the same wall. I have tried different sub cables and even tried setting up one sub using a wireless connection. I also purchased a ground loop isolator and that didn’t help.Absolutely nothing is helping. Are these subs just prone to this humming noise? It is seriously driving me nuts. Now i am thinking about selling both of them and trying something else??
Am i missing something somewhere and is there something else i should be trying? When i turn the subs off using the power toggle on the back of each sub, the hum goes away. It also goes away if I leave the subs in standby mode after about 15-20 minutes of not receiving a signal.
Any suggestions are appreciated.
