Docrobbi,
I have two JL 112s and was going to go with two 113s. I was lucky enough to get some good first hand advice from one of the designers at JL Audio and a long time recording engineer (who deals and uses the JL subs) and they actually talked me OUT of going with two 113s and into going with two 112s (so if they were looking simply to maximize revenues, they would have told me to just go ahead with the two 113s).
Years ago I had one REL Stentor 3 and I then added a second. In my opinion, the stereo pair was better than the single sub in every way. I am a 2-channel guy. I am a firm believer that two 112s will pressurize a room better and sound better than one 113 for both 2-channel and HT (especially given you aren't into super high spls). Since your room is not is cavernous in size, two 112s will knock you off your chair if the source material has the goods and the spls are even moderately high. They go deep with great articulation, transient attack and musical nuance but can also move LOTS of air. My room is a bit smaller than yours (2020 cubic feet versus 2437) but not a lot smaller.
Save the money and go with the two 112s and never look back would be my advice - but, as always, YMMV.
