back speakers are the same distance from the
listening position.
X-Curve

when played back in large rooms. The X-Curve setting
acts as a kind of re-equalization for home theater
listening, and restores proper tonal balance of movie
soundtracks.

Choose the X-Curve setting you want.
Use

to adjust the setting. The X-Curve is expressed
as a downwards slope in decibels per octave, starting at

increases (to a maximum of
-3.0dB/oct
). Use the
following guidelines to set the X-Curve according to your
room size:
If you select
OFF
, the frequency curve will be flat and the
X-Curve has no effect.

Note
1 • If you are using a Sound Pressure Level (SPL) meter, take the readings from your main listening position and adjust the level of each speaker to 75 dB

• The subwoofer test tone is output at low volumes. You may need to adjust the level after testing with an actual soundtrack.
