The S-X118S is the rugged outdoor version of our popular X118S Super Sub design. It complements our outdoor line arrays, delivering 35 Hz to 150 Hz sub-bass in the most demanding environments, such as football and soccer fields, stadiums, and amusement parks. Directivity can be omni or cardioid, depending on placement. An 18-inch, 700W low-frequency transducer with 4.0-inch voice coil provides minimal distortion and smooth, extended low-frequency response. It is available as a passive system.
