Do active speakers have high THD amplifiers?
Just to add to my first answer, it’s not that active xovers seem to my ear to add any distortion, but more that they "seem" to strip the "harmonic structure" from the music in the mids and highs and leave just the (admittedly "clean" fundamentals).
This is why I feel they sound thin from the mids and highs and leave things sounding too "sterile" for my liking
