Tip
The size of a speaker (LARGE/SMALL) is
determined by the low frequency characteristics.
The measurement results may vary, depending on
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 Speaker settings menu. Save the measurement
results first, then try to change the settings if you
want.
