My room is similar in size except we devided the room into two by have a couch in between. SO the speakers are about 3 feet away from the backwall, and the listening position is about 8 feet from the speakers. I set up the Encores with woofers firing towards the backwall per Verity's recommendation. 3 ft is just too close to the backwall, that the bass sounded boomy. I have not tried turning the woofers to face forward. What I did was to put my DIY room lens (made of those kid's foammy swimming noodle stick things) against the backwall right behind the speakers and the bass issue was resolved.
I have the Encores with the updated revelator tweeters.
