The size of a speaker (LARGE/SMALL) is
determined by the low frequency characteristics.

the position of the optimizer microphone and
speakers, and the shape of the room. It is
recommended that you follow the measurement
results. However, you can change those settings in
the SYSTEM menu (page 48). Save the
measurement results first, then try to change the
settings if you want.
