Subwoofer experience with for Joseph Audio Pulsar

Seeking feedback on  how easily or not the Joseph Audio Pulsar monitors plays with subs?? How easy is it to blend the sound? The subs I would be using will be the Rhythmik 12F servo sealed subs. 

Thank you in advance for your feedback.

I have used the Rythmik subs with Joseph Audio Pulsars and Perspectives.  This is a fabulous combination, but I am using a DEQX as the crossover.
