Curious, when I set a bass preset up using this method and I mute the volume block for low's, I barely hear anything from the high's (Right Only).
I have to turn the freq in the X-Over down from 800 Hz into the 500's or so to hear a similar level to what you demonstrated here at the start of the preset build (pre-amp block).
I guess the 800 Hz method is dependant on the pickups in the bass?
