i used the wisdom sub with my Rockport Mira Monitors in a 2 channel only system. I ran the monitors full range and dialed in the sub with its built in amp and crossover controls.
The setup certainly added to the monitors. I liked to keep it dialed in to the point where it was hard to imagine if it was even on or off, until you actually flipped off the power on the sub. That subtlety worked very well for me and added those very necessary lower octaves.
The wisdom was excellent. I do not have a ton of comparison experience with subs, but I'd like to think I have pretty good ears, and I was very critical/skeptical/cautious when adding the sub. Keeping the monitors sounding beautiful was an ultimate priority.
I ran a Bryston electronic crossover for a while, but in the end, preferred the sound when the Rockports ran full range.
Lastly, the SCS Sub has some convenient placement flexibility, and has a very different form factor than most subs, which added to its appeal.
good luck!
