The QD-Bass system radiates sound in 4 horizontal directions, while the YST II system produces stable, energetic low-range tones between 50 to 150 Hz. A notable feature of the Yamaha NS-SW325 is its Bass Action Selector System (BASS), per which users can choose between Music and Movie modes with the simple flip of a switch.
