I own Thiel 22's. My room is 15x17 and with 22's, I've had to position my speakers almost four feet into the room away from the front wall and almost three feet in from the side walls. With that in mind, I feel that the 3.6's would be a little on the large side for your room. If you are considering the 3.6's, I'm assuming your budget would allow you to add good musical sub to the 1.6's or upgrading to the 2.4's which is a huge improvement over the 2.3's.
