From the Manufacturer
The 121 powered audio system combines solid value with trusted performance, enhancing the overall listening experience as you play games, listen to music, or watch movies. The system easily connects to PCs, gaming systems (with the included Y adapter), portable CD players, and other audio sources. The ported wooden subwoofer adds a new level in gaming realism, while the 2-inch full range drivers deliver a full spectrum of sound. The system includes built-in on/off, master volume, and subwoofer volume controls, along with a headphone jack for private listening. The speakers are also magnetically shielded for use near video monitors. Busy users needn't fret, as the system gets up and running in mere seconds due to the color-coded cables.
