The three factors that get traded off are box size, efficiency, and bass extension. Greater cone size in the same box size often means higher efficiency, and therefore less bass extension. The box sizes are pretty close (the Paradigm is maybe 10-15% bigger), and as cone size would predict the Paradigm is also slightly higher in efficiency. I would expect the real-world anechoic -3 dB frequencies of these two speakers to be within a few Hz of one another, assuming their rated efficiencies were measured with the same yardstick. If not, then all bets are off.
