Yes, I use a sub with them. I try to carefully adjust it with the crossover starting at its lowest point and adding volume until I get a seamless "match". Then, I can up the crossover a bit IF I feel it necessary. However, I use my REL sub to merely add dimension, space, and a low end frame to the music. The objective is to not hear it specifically.
The Cornwall IVs are way more sensitive to placement than my Forte IIIs were. I actually got a little frustrated dialing them in.
