hey everybody. for the moment i am using th efollowing speaker set up Monitor audio rx6 fronts, MArx1 rears and the Rx center. i am not realy happy with the surround sound of the rears (yet) My room is 4 by 5 meters with the back of the couch against the 5 meter wall and i only have about half a meter of place on each side of the couch to put my rears. so i have put my rx1's in that place pointed to me. is it maybe better to by Rxfx speakers and put them on the back wall for a better surround sound? or isn't that a good idea if there is no place between the couch and the wall?
