Designed to provide powerful sound and rich bass, the Z333 Speaker System with Subwoofer from Logitech can be simultaneously connected to two sources using its integrated audio inputs: 3.5mm input and RCA inputs. The Z333 delivers 40W RMS and 80W peak power with its dual 8W satellite speakers and 24W subwoofer for crisp, clear sound that adds another dimension to videos, games, music, and more. Power, volume, and a 3.5mm headphone jack are all easily accessible via the wired control pod, while bass levels are adjusted using a control knob on the subwoofer.
