If your room is pretty big and your subwoofer lacks the output to energize the full room, your speakers may be doing a better job of playing down low, and might integrate just fine with large settings. It's really hard to tell unless you're in the room, hearing the system. In acoustic treatment threads I've seen guys do all sorts of crazy tricks and setups, you can make a lot of different things work.
In the end, just play around with it and settle on what sounds best. If you can't tell much of a difference, run them large and just enjoy their delicious output. Those speakers are so room filling and powerful it doesn't surprise me that they sound that great running full range.
