Product description

The KSLi-SUB is an installation specific cardioid subwoofer for the KSLi system. It can be used to supplement KSLi8 and KSLi12 cabinets. When the KSLi-SUB Mounting frame is used, KSLi-SUB cabinets can be flown as pure SUB columns or in mixed arrays in connenction with KSLi-TOP cabinets using the additional KSLi-SUB Mounting adapter. The KSLi-SUB cabinet is an actively driven, 2-way bass-reflex design housing three long excursion neodymium 15“ drivers. Two drivers face to the front while one driver radiates to the rear of the cabinet. The front and rear facing drivers operate in independent bass reflex chambers and are driven from separate amplifier channels. The cardioid dispersion pattern reduces unwanted energy behind the system, resulting in less excitation of the reverberant field to deliver highly accurate low frequency reproduction. The frequency response extends from 36 Hz to 105 Hz. The KSLi-SUB cabinet incorporates front and rear rigging strand. The cabinets are constructed from marine plywood and have an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front and rear of the cabinets are protected by rigid metal grills.
