Congratulations on your purchase of a Gateway® SW103/SW203/SW303 powered subwoofer. It will give your stereo system unparalleled low frequency output. Bass frequencies are critical to realistic sound reproduction. After you’ve hooked up your SW103/SW203/SW303 subwoofer, you’ll discover just how much “punch” and depth you’ve been missing. No matter what kind of music or videos you listen to...whether you listen to it loud or soft, you’ll experience sound that’s richer and fuller.
