About the JBL PRX618S-XLF

The JBL PRX618S-XLF extended low frequency subwoofer was designed and engineered to provide sub bass frequencies with accuracy and power. Used as a single sub in a sub/sat system or in multiples as part of a scalable, large format sound reinforcement system, the PRX618S-XLF performs with extreme efficiency and control. The subs are stackable and lightweight, ensuring quick set-ups and teardowns and due to their rugged construction, they are perfect for AV rental inventories. With a pole receptacle (that accepts a SS4-BK or SS4- BK24) on the top panel and integrated stereo pass-through, this is the most powerful low frequency complement to the PRX full-range systems. The addition of a polarity reverse option further enables system optimization.

The PRX618S is a high performance self-powered subwoofer system. The PRX618S is comprised of a powerful 2268FF Differential Drive dual voice-coil and magnetic gap, neodymium woofer driven by a 1000 watt (dual 500 watt) Crown Class-D power amplifier. Dual-Bridge Technology directly links discrete amplifier channel outputs to each voice coil in the Differential Drive woofer. Electrical power transfer to the transducer is optimized for more power performance. A proprietary DSP chip is at the core of a fully featured input section, providing user selectable cross-over functionality, polarity optimization, protection, dynamic limiting and discrete component optimization.

The amplifier input panel offers stereo inputs with XLR or ¼" jack compatibility. A user selectable crossover ensures a smooth transition to full-range system connected to the stereo outputs. Signal present and limiter lights indicate the system status and assist in setting the optimum level, via the level control knob.

The JBL PRX618S-XLF cabinets are built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, lightweight poplar plywood made structurally sound with tongue and groove joints. PRX618S-XLF cabinet is protected by JBL's tour proven DuraFlex finish. Grilles are made from dent-resistant 16-gauge steel and handles are made from lightweight, glass-filled nylon for added strength and durability.
