Applications :
  • The 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 light-weight ensuring quick set-ups and tear-downs. And due to their rugged construction 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-thru 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-XLF is a high performance self-powered subwoofer system. The PRX618S-XLF 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 inch 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.
  • All PRX600 cabinets are built from a combination of 25mm (on the top and bottom for added rigidity) and 18mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. All PRX600 Series cabinets are protected by JBL’s tour proven DuraFlex™ finish. Grilles are made from dent-resistant 16 gauge steel and handles are made from light-weight glass-filled nylon for added strength and durability.
  • Special note: JBL highly recommends that no more than 70 lbs of weight be placed on a speaker pole that is mounted to a PRX618S
    or PRX618S-XLF.
