THX Ultra2 Subwoofer Setup
With a THX Ultra2 subwoofer (or one that has a response to 20Hz), depending on the position of the subwoofer and the walls in your listening area, you may experience overly resonant frequencies in the bass. If you have this problem use the THX Ultra2 subwoofer setup to switch on boundary gain compensation (see About THX® on page 107 for more on this).
Note
•If you don't have a subwoofer, you won't be able to select this setting.
•Selecting YES in step 2 (below) cancels the setting you made for Bass Peak Level on page 91.
1Select ‘Ultra2 SW Setup’ from the THX Audio Setup menu.
2Specify whether your subwoofer is THX Ultra2 certified (or can respond to 20Hz).
You can only switch on Boundary Gain Compensation (below) if you have selected YES for this setting.
3Select either ON or OFF for the Boundary Gain Compensation setting.
4When you're finished, select RETURN and press
ENTER.
You will return to the THX Audio Setup menu.

Note
