Floor standing
The subwoofer is under normal conditions always placed directly on the floor. This is taken into account in the basic design and the basic settings of the AIR system.
Placement in the corner
This is a π/2 radiation, which yields a gain of 18 dB in the frequency range where the monitor is considered to be
Most standing waves have their maximum in the corners of the room. Especially if the room has a cubic or shoebox shape (the room having all walls in parallel). The placing of the subwoofer in the corner may cause uneven sound distribution of the bass.
The corner position is normally only preferred if all opposite surfaces in the room are not in parallel.
Adjacent to a wall
This is a π radiation, which yield a gain of 12 dB in the frequency range where the monitor is considered to be
This position adjacent to a wall is commonly used, and it can be OK, but it must be noticed that the subwoofer should neither be placed in the middle or in the quarter points between two sidewalls if these are in parallel.

Free standing
This is a π radiation, which yield a gain of 6 dB in the frequency range where the monitor is considered to be
The free standing position is highly recommended in all cubic and shoebox shaped rooms.
In any case: Try to avoid placing the woofer on the half or quarter lines between walls.
