db Audiotechnik The 2 Way 18 Inch Drivers Passive Speaker System J Sub Loudspeaker
Product description
The J-SUB is the cardioid subwoofer for the J-Series. It can be used to supplement J8 and J12 cabinets in various combinations, either flown or ground stacked. When the J Flying Frame is used J-SUB
cabinets can be flown in columns of up to 16 cabinets or inserted on top of a J8/J12 line array column.
The J-SUB cabinet is an actively driven 2-way bass-reflex design housing three long excursion 18" drivers, two drivers face to the front while one driver radiates to the rear of the cabinet. Front and rear drivers are driven by separate amplifier channels and operate in independent bass reflex chambers. Through its cardioid dispersion pattern this setup avoids unwanted energy behind the system and greatly reduces the reverberant field at low frequencies providing highest accuracy in low frequency reproduction.
Its frequency response extends from 40Hz to 350Hz (±3dB).
The cabinet is constructed from marine plywood and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front and rear of the loudspeaker cabinet are protected by a rigid metal grill. Each side panel incorporates four handles and mounted on the rear panel are four heavy duty wheels.
