D&B Audiotechnik Z0786.000 KSL-GSUB Subwoofer with NLT4 F Connections

The KSL-GSUB is a cardioid subwoofer for the KSL System. It can be used to supplement KSL8 and KSL12 cabinets, either ground stacked (KSL-GSUB) or flown (KSL-SUB).

The KSL-GSUB 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 (33 Hz to 75 Hz in INFRA mode).

The KSL-GSUB cabinet has no rigging components and is intended for ground stack purposes. Two runners extend from the front to the rear to protect the bottom panel. Two correspondingly shaped recesses are incorporated into the top panel which accept the runners and prevent cabinet movement when multiple subwoofers are stacked.

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.

Features:

• INFRA mode frequency range from 33 Hz to 75 Hz
• Cardioid output pattern rejects the transmission of energy towards the rear
• Exceptional efficiency and system headroom
