ASUS Xonar D-KARAX PCIe 7.1 Karaoke Audio Card 

FlexBass is an advanced bass management and enhancement mechanism that 

allows you to select each satellite speaker’s type for optimal sound performance.  

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 to the subwoofer or large speakers.

Click this button to disable or enable all FlexBass functions.

Select the speaker type connected to the Xonar D-KARAX.  

If your speaker type cannot handle low-frequency signals 

(bass), select “Small” speaker type.  Xonar D-KARAX will 

filter out the bass signals and send them to the subwoofer 

channel.  If the speakers support full-range signals, you can 

select the “Large” speaker type.*

*In most cases, low-cost desktop PC 2-channel speakers 

are small-type speakers.  Refer to speaker’s specifications 

or consult your speaker vendor to identify correct speaker 

type.  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.

Small/large speakers are identified by their colors:

Orange:

 

large speakers

Green:

 

small speakers

Standard speakers that cannot produce low frequencies are considered “Small” 

while wide-band speakers that can product low frequencies are categorized as 

“Large.”
