Single vs. Dual Subs


It's common wisdom that dual or multiple subs help smooth out bass response in different spots in the room, but what about for a dedicated listening room with a fixed single listening position? What do two subs add to the music presentation that a single dialed in sub is missing provided that single sub is dialed in perfectly for the listening position?
Caveat: not interested in the SWARM method or multiple subs at the moment, strictly comparing single to dual subs

“Two or more subwoofers also help in reducing low-frequency distortion and offer improved dynamics over a single subwoofer. This is a simple function of having more radiating area, plus more power on tap.”

 I suspect that we all understand that bigger drivers and more powerful amps are usually good for bass. ‘Twas ever thus.  But many of us have $, space and spouse constraints.
I’m considering getting sub(s).  My question is more like, “for the same money, are 2 10” subs likely better than 1 better (and more powerful)  sub?”   E.g., 2 REL t/9i vs 1 REL S/510 cost about the same. 
For that matter, is there a consensus (here? Lol) that REL is likely better for 2-ch than JL Audio or SVS?
