When people say "open floor plan" that worries me. To calculate the air volume that the subs are working into, you need the volume out to solid floor-to-ceiling walls in all directions. Out to a couch the defines the boundary between the great room and the next room over isn't sufficient. IOW, the air volume your sub(s) have to work into might actually be far greater -- it might be the entire floor of the open floor plan house that the great room is part of.

In general, the bigger the air volume, the more work the subs have to do to produce the same levels. So bigger air volumes imply bigger drivers, or more drivers.

I can guess (and it's only a guess) that a room that size is going to be a challenge for a sub that small. That said, much depends on what you're listening to, and how loudly you want to play it. Also, how low you want to go. For example, if you're really interested in playing a movie like Ready Player One at reference volume (master volume at 0 dB), and you want to feel all the sub-sonics down to, say, 10 Hz, then the entry level LV12R, or even a pair, isn't going to prove satisfactory. Won't play loud enough, or reach deep enough.

If OTOH, you're more interested in playing Mozart's Piano Concerto #23 while you eat dinner (much quieter than the Ready Player One demo, and the lowest note on a modern 88 key piano is 27.5 Hz IIRC, and Mozart's keyboards didn't go that low), then one or a pair of LV12Rs might work out just fine.
