Hi my Ethos are sounding 'flat'pretty much all bass hardly any mid or highs, local dealer tech saying may need to change panels. Wondering if anyone has had a similar issue

Hola Purdey,

Khen is giving to you the best advice. It looks that your panels are not working right. If the panels were totally dead, then the culprit is the PSU (power supply unit), but it looks that you are still getting sound from the stat panels. Contact ML about your problem, they will guide you step by step of how to track the problem.

Usually the problem is at only one speakers, but yours looks to be both stat panels. You can do the washing procedure of the stat panels. Usually the panels come back to sing again after the washing. Here is how to do that: Martin Logan Shower Cleaning PDF

Happy listening!

I had my depth i sub serviced under warranty at my dealer and everything went well with that. It was actually in 2x.
