Hi All,
To add to the thread, I have reported a failure of speakers bought in 2017 at the end of 2017 here Hardware reliability issues with the KEF LS-50W - #108 by astroinfinity
Now they have failed again - I get a popping sound in the left speaker and a lot of distortion, no ability to reset. They were very lightly used. I feared this day would come after the first issue. Now I am out of warranty… And to think I have considered upgrading to WIreless II.
