JerryW Posted March 1, 2020 Report Share Posted March 1, 2020 I have a KLH Twenty One FM radio that we bought new in the 1970s. My wife would like me to get it working again. The problem seems to be that the speaker distorts ("flapping sound") at high volume/bass content -- Ok for voice range but music creates the problem. No obvious tears in the surround. Your advice on what avenue to go down next to restore quality sound is much appreciated. Has anyone found an off the shelf speaker part that is a good replacement should it come to that? Are there other things I should do first? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
