I am running Odyssey's in a 12x20 room.I do have 16x78 ASC bass traps in all 4 corners.It helps if you absorb some of the rear wave.I have the bass traps directly behind the Odyssey's absorbing the rear wave with the absorbtive side facing the speaker, the traps in the back of the room have the reflective side of the trap facing into the room.
I owe a huge debt to member Bernard for suggesting to put the tube traps directly behind the speakers to absorb the rear wave, night to day difference.I was amazed to say the least.Many thanks!!!
I think it will work out great for you.Room treatments do make a huge difference to the final outcome of what you hear.
