Your room is certainly large enough for the M80s, especially with the one side being open. It is really the proximity to the wall that you may need to adjust if you are getting too much bass in your room, or better at your listening position. Large speakers with the capability of reproducing low bass frequencies can interact with the wall behind them and depending on where you are seated this will manifest itself as too much bass. If this should happen in your room, then you need to move the speakers out from the wall a bit.
