d&b audiotechnik Z0760.000 SL-SUB Subwoofer with NLT4F Connector

The SL-SUB is a cardioid subwoofers designed to compliment the GSL8 and GSL12 loudspeakers. The SL-SUB rigging hardware allows columns of up to 14 cabinets to be flown. This subwoofer comes with actively driven, 2-way bass-reflex designs housing three long excursion 21″ neodymium drivers. Two drivers face to the front while one radiates to the rear. 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, lessens stimulus of the reverberant field to deliver highly accuracy low frequency reproduction. The frequency response extends from 30 Hz to 90 / 70 Hz. The SL-SUB cabinet incorporates front and rear rigging strands while the SL-GSUB has no rigging components and is intended for ground stack purposes. The cabinets are constructed from marine plywood with an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front and rear of the subwoofers are protected by rigid metal grills backed by an acoustically transparent and water repellent fabric. Two runners extend from the front to rear to protect the bottom panel. Two correspondingly shaped recesses are incorporated in the top panel accepting the runners and preventing cabinet movement when subwoofers are stacked. The side panels incorporate four recessed handles and four heavy duty wheels are mounted on the rear of the subwoofers.
