The SCM-20 would work quite well and you won't need a sub ( unless you prefer huge amount of bass.) The Proac SC and Tablet will not do the job in your space. Even the SCM-10 is too small for the room. The B&W 805s is also too small for the space.
Everything you listed and suggested by folks here requires a sub to go along with it. I personally don't enjoy music with sub because it is very hard to get them in-sync. I'm very picky about. It will sound un-nautral and muddy on the low end. Without the sub, they'll sound too thin in your space.
However, there is a catch with ATC SCM-20. You need a good amp to go with it. I personally think the passive sounds better with tube amp when compared to solid state amp or the active version. A good matching amp under $1000 would be a Harmon Kardon Citaiton II or a Lafayette KT-550. For over $1000, you can get a pair of McIntosh MC60, Heathkit W-6M, or the McIntosh MC-275 $$$, Fisher SA-300... For Solid State, $$$$ ... anyway, just my 2 cents.
