In your smallish room, a VTF3 is overkill. you might not be able to turn it down enough!
The VTF2mkIII I use is fine into even my 5000ft/cube room.
It even plays well with my panels.
Your problem may be a near-cubic room.
Approaches to 'fix' may include, putting sub close to seating position....this recommended by Dr. Hsu. I heard this in his cheesy demo room up in Orange County, Ca.
OR. a pair of subs to minimize standing wave interaction.
and finally:: Some kind of room modifications with bass traps.
In <2000ft/cube multiple subs may be nutty/expensive, so I'd go with 1st or 3rd rec.
