jason str Posted May 1, 2020 Share Posted May 1, 2020 Hard to diagnose issues without hearing the unit but its likely the amp or woofer surround is bad. These are the most common problems as well. Unless you are handy and can do repairs yourself it may be time to get some new gear. I recommend a set of bookshelf speakers and for power whatever fits your situation (receiver, integrated or mini amp). 1 Quote Link to comment Share on other sites More sharing options...
M_Klipsches Posted May 5, 2020 Share Posted May 5, 2020 The sub/volume pod in mine became scratchy. I bought a replacement from Klipsch for $20. Mine didn’t make a “thunder” noise so, maybe a different issue? Could be worth a try though. Quote Link to comment Share on other sites More sharing options...
timdog5000 Posted May 6, 2020 Share Posted May 6, 2020 Many videos on youtube to fix this issue. I have a set of ProMedia 2.1 in all four of my kids bedrooms and occasionally we apply the methods in videos to clean with electronics contact cleaner inside the speaker with the electronics and volume knob. Very easy to do for even a novice. HOPEFULLY it will work for you as well. 1 Quote Link to comment Share on other sites More sharing options...
