The Pulz  Contrabass SB600 is the result of extensive research in very low frequency (VLF) reproduction in enclosed spaces. This system consists of a long throw 10” woofer powered by a 600 Watts Class D amplifier. The compact size of the subwoofer makes it suitable for use in small venues and retail outlets. The Class D amplifier is powerful enough to drive another SB600P passive slave subwoofer. The two channels of professional balanced XLR inputs can be switched for sensitivity between consumer and pro standards. A continuously variable control is provided to make precision level settings convenient.

The user selectable 24dB variable low pass filter is tunable from 50Hz to 200Hz. Assisted with the polarity switch, the Pulz Contrabass SB600 can be matched to any satellite system or surround sound system with ease.

Even though the Pulz  Contrabass SB600 is an exceptionally flat subwoofer system, down to 30Hz, the real life frequency response will be dominated by the room itself. Corrections in this regard are mandatory. A professional grade single band parametric notch filter has been provided to alleviate this problem. This feature is accessible to qualified installers.

The Ensemble series comes in a very high gloss piano finish which blends elegantly with most living room interiors.
