Placing a speaker near to a room boundary will increase its bass response. Four preset EQ curves are provided to
compensate for this effect and maintain a flat, neutral response. The preset EQs are selectable via the encoders or
SoundAlign network interface. The typical bass response for each speaker position before and after compensation is
shown below (red = no compensation, green = correct response).

Console or desktop reflections can cause a narrow-band peak in the lower-mid frequency. This can be corrected with
a Desk Filter EQ option which is accessed via the encoders or the SoundAlign network interface.
