That's a very small room : I'd strongly advise against any Vandersteen : even the 1's need a lot of room around them to sound best.
I don't think any floor standing speaker is going to work great in that space.
I would really do a stand mount monitor in a somewhat near field set up, and supplement with a small sub. I.e. The Focal 906 + maybe a JL Dominion D108 sub (8 inch). The 906's are forward ported, so you don't have to worry about a rear port being to close up to a wall. And the inverted dome tweeter has wide dispersion. The 8" sub is plenty for that size room.
That combo at retail will run you about $2200 if you get the Dark Walnut color 906's, which are on sale for $999.
