I have been struggling to enjoy my 3D80 purchased recently and couldn't seem to get the EQ to sound right so i decided to use some test tones and a mic to calibrate the response of the boombox to a flat response across all frequencies. The resulting settings have made the sound quality much better but the actual EQ settings are not what i would have expected. I do wonder if the graphics printed on the EQ are a clue as to this odd behaviour. Here is a pic of the flat response settings. I would have expected the sliders to have been in a row across the middle. Could someone else with one of these verify they get the same improved result with these settings. 3D mode on and Surround off. EQ as below.
