From what I have seen from the vague KTX-100EQ owners manual. The PXE-H650 is considerably more capable. It appears that we don't have any X-over adjustment after tuning nor do we have any EQ (except for bass and treble). It appears we get subwoofer level along with the aformentioned bass and treble control. No three bands of parametric EQ after the fact. I feel... let down.
