Pioneer TS-WX140DA – Space Saving Sub Underseat Active Subwoofer 170W. Pioneer launches another product in its generation of Class-D amplified subwoofers integrating DIGITAL BASS CONTROL. This unique feature generates three selectable Bass Modes: DEEP, NATURAL and DYNAMIC, producing 170 Watts of strong, rich, deep bass that you can feel, without giving up space. Users can easily control and customise the three bass modes directly from the supplied wired remote control, and you can easily mount the TS-WX140DA under the front seats or in the boot.
