With a mic and a spectrum analizer I found the LF Flat and LF Raw modes has the hi driver iff, but has a normal ahi freq response compared to the speaker models. It appears to me that rhe speaker models has an Eq applied to it that cuts the low and Hi end of the spectrum.... something that sounds good from XLR to PA, but sounds muffled directly to the speaker. I think Line6 forgot NOT to apply this Hi and alow cuts to the speaker emulation models when it is heard from the apowercab itself.... and only apply that to the XLR outputs. Thoughts?
