The MAXX's will work in that size room, you may need to add some bass traps depending on position and bass loading in the room.
The best course of action would be to install the speakers and then have an acoustician sweep the room and then use placement and bass traps to ameliorate any problems which will occur.
In most rooms the major problem is bass loading problems rather than overt problems with the higher frequencies.
The Maxx2 are better than the WP 8 however, there are other speakers even in the price of a used pair of Maxx that you may prefer.
