Being new to subs, isn't there an obvious danger of over loading this little room with too much bass energy?
Where did you get this bogus notion? What does it mean: “loading this little room with too much bass energy”.  Do not repeat somebody else’s foolishness!

Or is it more an issue of having 2 distinct sources for balance?  I don't think we're talking about stereo imaging issues at these low frequencies.
It is very much incorrect. The sources hold stereo information does to sub low frequencies and all stories that at certain frequencies only one LF sources might be used are juts the sick imagination of ignorant audio-reviewers or the mental defecations of audiophile with Audiogon intelligence. In addition, the LF sources MUST not be positioned BETWEEN the HF sources. How one would be able to accomplish it with one unit?

Regardless, before diving into the masochistic hell of trying to locate 2 gigantic subs, maybe it's a better idea to figure out how to use 1, properly.  If one sub is challenging, than 2 are more challenging. 
Why? You ingrate LF module with of MF section. What the differents how many of them?

My one sounds ok, but it's all over the board.  Sometimes too loud and booming, and sometimes like it isn't there at all.  Varies tremendously by program material.  Practicing integrating with my other speakers was way easier by comparison.  bty, the Seismic has a 4th order crossover ~70Hz, ~5 or 6 dB bass boost at 30Hz, and use a folded horn path. I know your (low) opinion of these tools, but it is what it is....
5 or 6 dB bass boost at 30Hz? I remember Bruce told at the Asylum that it had 15dB at 25Hz. I think it starts as 65hz and somewhere in the middle it changes to 35Hz bell. I do not remember. Whatever it is it is not bad and I generally like it, practically for the price.

About RTAs, Bruce and my local guy, both advise that RTA "might" help, but just as likely lead on a wild goose chase.  They advise against the RTA.  But you know me, I'm kind of stubborn and may pick up an RTA anyway...
I do not know what motivated them to “advise against the RTA” as there are no other ways to do it. The only justification thing of their “advise” is that in your room with this LF module you have NO WAYS to do anything if something is incorrect. So, you get is “as is”. All the rest comes with a high resolution RTA. There is another reason why Bruce might advised you “do not go for RTA”: the 95% of Bruce’s customers are unspeakable Morons who do not need nether RTA not anything else. They are that Audiogon-Audioasylum intelligence that I mentioned before. Bruce knows it and he understands very well who his customers are and what result they get in their rooms. Consequently he does not even accustomed to deal with consumers who have bass demands more evolved then “loading room with bass energy”… Anyhow, you might borrow a RTA for a weekend for $100 and it will be a good investment. Then you might begin to educate yourself about bass… my estimate that it will take for you 3-4 month
