I would worry less about power and more about bass response depending on your musical needs...mmgs have limited response especially in a room 12 x 15...however if your primer choices are vocals,acoustic guitar,etc they would be perform fine...however...with any bass driven music like rock,reggae, electronica,etc,,,they will struggle...could add a sub....but at this price range...might be best to go with a driver speaker that can produce some LF...happy xmas
