Smallest Room For Revel Gems

Hi all. Will be moving places again and thus the sound system needs to be relocated unfortunately. I just wanted to ask for any suggestions/advice as to the smallest room which you think the Revel Gems could work in (not looking for absolute optimum - that I will achieve when I have my own dedicated listening room :) but just don't want to set something up which is doomed to sound terrible to start with.

Currently looking at a very small room, around 5.5m x 4.5m, thin-pile carpet over concrete floor, wooden cabinets on one end, heavy curtains on the other.
