I have a 12 x 17 room with Response 2.5. I used to have the Response 2 in the same room. The speakers are 4 feet from the wall behind them and two feet from the side walls. I sit about 8 feet from the speakers.
I think may be able to improve your imaging by moving the speakers out further into the room and further from the side walls assuming that is possible. I would also try adjusting toe in and adjusting your seat height to see if the matters.
