This compact, 2.1 speaker system delivers clear audio and enhanced bass via a 3.5mm connection. It includes a compact subwoofer (81/2" x 6" x 9") and two satellites (3-1/4" x 3-1/4" x 5-3/4"). Compact speakers take up minimal space on the desktop, and the subwoofer fits right under the desk. Z213 Multimedia Speakers deliver clear audio and enhanced bass from the down-firing subwoofer. Easily access power, volume and the headphone jack using the wired control pod. Customize your listening experience by adjusting the bass level with the dedicated control knob on the back of the subwoofer.
