I've also included the bass "Sweet Spot" on the diagram if that helps at all?
I have a PC12+ in a similar size room 13x14x9 and in 16hz mode I'm told by Ed from SVS that I should be getting around 13hz or so extension down low. It definitely rocks the room. Fortunately I don't really have any placement issues as I get a pretty even bass response (judged by ear) across all 4 seats of the sofa.
One thing I would do with your setup is to move the couch off the back wall by as much as you can, 2-3 ft would be good. I think that would help.
I had a "super" cube 8000 prior to my SVS. It was OK and had decent sound and output above 25hz or so, but trailed off pretty fast and was SOOOOOO overpriced. To make matters worse, where I live I can't sell it not even for half price.
Anyway, the SVS PC subs are great and with the + or Ultra version being tunable I think you'll get as good of extension as you have now.
