Offroad, where in California are you located? If you are in So. Cal, you could swing by the office and audition some subs.
The VTF-2 Mk3 would work great in your room, and offer some cost savings too. Based on your preferences you could choose to run it in maximum output mode or extended bass mode. I would put the sub sideways behind your couch if possible.
If your budget allows it, and the larger size is of no matter, then look at VTF-3 Mk3 too. That model has dual 4" ports and a bit lower port tuning too. But as long as your room doesn't open up into other large rooms, then the VTF-2 Mk3 should be able to fill the room very well!
Sincerely,
