8.6 FlexBass FlexBass is an advanced bass management and enhancement mechanism that allows you to select each satellite speakers 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.

No Item Description

1 On/Off Click this button to disable or enable all FlexBass functions.

2 Small/Large speaker option

Select the speaker type connected to the Xonar U3 PLUS. If your speaker type cannot handle low-frequency signals (bass), select Small speaker type. Xonar U3 PLUS 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 speakers 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.

3. Picture for Small/ Large speaker

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.
