In small room acoustics, you must treat the low frequency issues first and foremost. The fundamental low frequency issues produce harmonics that extend through the middle and higher range frequencies. If you treat the fundamentals, you minimize the impact at the middle and high frequencies. In a room this size and volume, you have major treatment issues starting at 33 Hz. and going through 225 Hz. Moving speakers around in a room this size and usage will not have the effect you desire. Treat the room fist and then set up within the treated room.
