Are you contemplating a pair of the VTF-2Mk3?...If I were you I think I might just opt for a VTF-3 HO. You may get a bit more volume with the two subwoofers, but you'd have an easier time trying to integrate one sub into your room rather than trying to integrate two...you could co-locate two subs (usually accomplished by stacking them) but I don't know if that would work for you aesthetically. The single VTF-3 HO would also be a little less than the dual VTF-2Mk3s.
The VTF-3 HO should be enough sub for your room despite it being a single 12". I'm running an SVS PB-12+ (
gratuitous SVS mention!), which is pretty much the equivalent of the VTF-3 HO in terms of size and wattage, and it's performed well in my "open floorplan" system. You should have no problem reaching the levels you need in your dedicated room with the VTF-3 HO.

I think thaat, because you actually have two subs, it's more correct to say 500 watts x 2. The reason being is that just by virtue of adding a second sub, you gain approximately 6dB in volume intensity.
Let me see if I can explain this correctly...
Let's say you have 1 12" sub powered with 1000 watts that can play to 100dB.
The same sub would play to 97dB with 500 watts...the doubling/halving of power to a transducer equates to a 3dB increase/decrease in volume intensity (respectively).
But it you take that single woofer that plays to 97dB with 500 watts and you add sonter exacly like it to the setup, you gain approximately 6dB which would amount to a total system volume of 103db for the two woofers powered at 500 watts each.
I hope that doesn't just confuse the issue even more.
