ASUS Xonar DG SI 

FlexBass, an advanced bass management and enhancement mechanism, allows 

you to select each satellite speaker’s type for optimal sound performance from the 

speakers. (Small: common speaker that cannot produce low frequencies; Large: 

wide-band speakers that can produce low frequencies well). It comes with an 

adjustable crossover frequency for the boundary of the bass signals. FlexBass will 

filter out the bass signals from small speaker channels and redirect them all to the 

subwoofer or Large speakers.

Click this switch to turn on or off all functions on this 

FlexBass page.

Select the speaker type that you connected. If your speaker 

type cannot perform low-frequency signals (bass), select 

“Small” speaker type and Xonar DG SI will filter out the bass 

signals and send them to the subwoofer channel. If those 

speakers are full-range, you can select the “Large” speaker 

type. 

Note: Usually, low-cost PC’s 2-channel speakers are  

small-type speakers. Refer to the speaker’s specification. 

If you have any questions, consult your speaker vendor. 

However, common 2.1 speakers with a subwoofer should 

be categorized as Large speakers because the subwoofer 

can redirect the bass signals inside the two channels to the 

subwoofer speaker automatically.

Colors for small/large speakers are different.
Orange: large speakers
Green: small speakers

Adjusts the cut-off frequency (20~250Hz) for LFE (low-

frequency effects) signals. Xonar DG SI will filter out the 

bass signals below the crossover frequency from small 

speaker channels and forward them to the subwoofer. The 

higher the crossover frequency, the more bass signals will be 

subtracted.
