Fist of all you are getting this all backwards. Choosing the chairs based on the transducers you already have seams to be wrong way to choose your home theater seating.
Second the chairs are Buttkicker READY, meaning that kinetic rubber isolators that decouple the chairs from the floor and damp the vibrations coming from the transducers and the plate that excepts the BK-mini-LFE or advanced BK4-4 buttkickers are factory pre-installed, and I am sure if you need to stay with the Clark Synthesis transducers you may be able to find a away to mount them.
Last but not least, the BK4-4 advanced buttkickers are quite powerful, and I honestly do no see why would you need any more power than that...
