The Volti Razz sounds excellent and is the most refined of the ones on your list. My only reservation is that they sounded a bit too smooth when I heard them however the crossovers can easily be adjusted by changing the snap in resistors with some guidance by Greg of volti who is very responsive.
A bit more midrange and these would have been perfect.
They would also have perfect synergy with your system.
The volti speakers greatly improve on the klipsch heritage sound because they are super well braced and have no cabinet colorations. makes them sound more like music and less like PA speakers.
I would not even consider the paradigms, no offense.
I am not a fan of the JBL voicing and tonal balance.
