Your Nautilus speakers are very refined, so you do not want a cheap sub to muddy up the bass. This is one reason I recommended the REL Stsdium or better.
I have a REL Storm III that I used for 2 channel until I got my latest speakers. In the past the Storm always made the room sound better. My new speakers have reached the point where that is no longer the case.
