THX Ultra2 Sub -
This setting is for use with a subwoofer that is certified to THX Ultra2 specifications. This
setting allows a means to adjust for excessive bass resulting from a boundary gain effect. Room boundaries such
as walls and other acoustic obstacles may increase the perceived volume levels of low frequencies. Depending
where the listener or the subwoofer is located, the listener may experience excess bass level. THX Ultra2 allows
for Boundary Gain Compensation to reduce the boundary gain effect and allows a more natural listening
environment. Select “Yes” if your subwoofer conforms to the THX Ultra2 standard or if the playback capability of
its bass range extends down to 20 Hz. Otherwise, select “No.”
