Here are some news about my bass prb in the right-side speaker.
I made a test : switching the ampl. output.
Left output connected to right panel, right output connected to left panel.
And then the empty bass was… in the left panel.
So it seems that the prb is about the output of my amp.
But what ? How is it possible to get no x-low bass on the right ouptut but normal in the left output ?
I never observed this prb with my previous Magnepan 3.5, the prb appeared last week with my new 20.7…
