Yes, the TV room is really an extension of the room to the left. The room to the left is 14' (top to bottom) by 30' (left to right), but movies/TV will be viewed where the subs are intended to be.
I did consider putting the front sub one third from the left wall and putting the other sub to the other side of the room. That may actually work better with main listening position and furniture arrangements.
I did edit my last post to say I could do the sub crawl with my VTF-3, but I don't have drywall up yet. I don't know if that will yield the best results, but I suspect it will still help me get the best placement later.
Thank you for the suggestion regarding the use of VTF-3s versus VTF-2s on the concrete slab.
