The 4,000-Watt VSX118B is a direct radiating passive 18" subwoofer that is ideally suited for a broad range of speech and music sound reinforcement applications in both fixed, portable, and touring audio systems. VSX118B’s superb low frequency reproduction makes it the perfect choice for deployment in clubs, bars, theatres and AV applications. A ported bass reflex system, the VSX118B features a high powered 18" low frequency driver that provides extended low frequency response to well below 40 Hz – for chest-pounding bass. Fast and accurate transient response enables the VSX118B subwoofer to generate copious quantities of tight low end output that is virtually distortion-free.
