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.
1 Select 'Ultra2 SW Setup' from the THX Audio
Setup menu.
2 Specify 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.
3 Select either ON or OFF for the Boundary Gain
Compensation setting.
4 When you're finished, select RETURN and press
ENTER.
You will return to the THX Audio Setup menu.

Surround Back Speaker Position

For the most effective results when using the THX Ultra2
Cinema and THX MusicMode listening modes (see Using
the Home THX modes on page 43) with the Advanced
Speaker Array (ASA) system (see About THX® on
page 107), it is required that you make the setting below.
Note
• If you don't have surround back speakers, or just have
one, you won't be able to select this setting.
1 Select 'SB SP Position' from the THX Audio Setup
menu.
2 Specify the distance of your surround back
speakers from each other.
• 0.0–0.3 m – Surround speakers up to 30 cm apart
(best for THX surround sound).
• <0.3–1.2 m – Surround speakers between 30 cm and
1.2 m apart.
• 1.2 m< – Surround speakers more than 1.2 m apart.
3 When you're finished, select RETURN and press
ENTER.
You will return to the THX Audio Setup menu.
