I once have the experienced of suspecting the panels when hearing the same thing on my Logans(Ascents). Sound (especially vocals) seems to be on different regions of the panel instead of through out. Bass was fine. So it must be the panels right? I was wrong! it is the audio transformer inside the backplates who's the culprit. Here are some info that will be useful:

1. Go to, service department and fill-in the service request form. You will get a response from Mr. Jim Power, head of the service department, asap.

2. Call them directly(Martin Logan) at 785.749.0133 and ask if you can speak to Mr. Power.

3. Go to, forum section and state your problems there. Theres a lot of people that can help you out there.

We, ML owners, have our own dedicated website that is full of information you know.

good luck!
