112Woofer Posted July 23, 2019 Share Posted July 23, 2019 I have a sw-112 subwoofer hooked up to a Yamaha amp/receiver as part of my home theater setup. I'll turn everything on and all is well for anywhere from 15 minutes to an hour and then suddenly a very loud buzz/hum start from the woofer. It practically shakes the house. I'm wondering what this could be and if it is something that can be fixed. Quote Link to comment Share on other sites More sharing options...
jason str Posted July 26, 2019 Share Posted July 26, 2019 Sounds like a bad amplifier. Any other systems to hook the sub to for testing to see if the issue follows ? Quote Link to comment Share on other sites More sharing options...
