raoul_duke Posted March 6, 2017 Share Posted March 6, 2017 I bought this Klipsch subwoofer (KSW-10) new around 1998. It's worked great for 19 years until last month. When I start watching TV or a DVD, I will usually (but not always) hear one or two loud "booms" in succession. It's not a part of the soundtrack. This happens about five minutes into the program but only if the sub hasn't been used that day. I'm getting settled into a show and out of nowhere it sounds like a heavy book hitting the floor from a top shelf. This never happened until recently and I made no changes to settings or setup. No sudden weather changes either. The sub still works, and I haven't heard it happen with music (even with a pipe organ CD.) I did try to turn down the level from '11' (yes, it really does go to 11) to '6'. It still happens and now more frequently. I searched Google, the FAQs and other forum posts and haven't turned up any answers. Has anyone run into this problem before? Thanks Quote Link to comment Share on other sites More sharing options...
