Please do not think I can hear the cabinet in any way. It is not like sound comes from the cabinet separate from the music like (and extreme example) the buzzing of a Honda Civic with a cheap subwoofer. I am talking sympathetic notes that are PART of the music. It would be like someone turned up a graphic eq to 10 in the 160-200hz range leaving everything else flat. Does that make sense or clear up any confusion? Another thing, volume has nothing do to with it. The sympathetic notes occur at the same proportion and ANY volume. And I have never played them very loud in the first place. That same problem occurred with the K-horns at varying low to mid volume levels.
