Christie® Vive Audio™ S Series subwoofers offer low distortion, low power compression and minimal turbulence to deliver extended low frequency response at extremely high output levels for powerful and deep bass. The S118 and S218 models are engineered for the reproduction of Low Frequency Effects (LFE). The S115 and S215 models can be combined with our LA Series loudspeakers to create full-range audio systems that can be used as screen channels or as corner surrounds for bass management. Integrated fly points offer installation flexibility.
