IN THE BOX
 
The PRX718XLF, 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 PRX718XLF performs with extreme efficiency and control.

For easy transport and setup, the subwoofer includes two injection molded handles, 16-guage steel dent resistant cloth backed grills, and an integrated speaker pole socket for SS4-BK or SS4-BK24 speaker poles.

The back panel of the speaker features two combination 3-pin XLR and 1/4" balanced inputs and a High Pass/Full Range pass-thru button. A gain control knob allow you to adjust the input signal on channels 1 and 2, and a pair of 3-pin XLR male thru connections enable passing audio to another subwoofer, powered speaker, or amplifier. The device includes a polarity button for inverting the subwoofer's phase and a button for turning on and off the power/standby LED on the front of the unit.

The speaker's crossover, dynamic limiting, component optimization, and selectable EQ boost is handled by a dbx type IV circuit. The subwoofer can be used by itself to reinforce the low end of a PA speaker system or in multiple subwoofer setups for increased crowd coverage.

  • The PRX718XLF 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 PRX718XLF performs with exceptional 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 PRX718XLF is a high performance self-powered subwoofer system. The PRX718XLF is comprised of a powerful 2278H Differential Drive® dual voice-coil and magnetic gap, woofer driven by a 1500 Watt Class-D power amplifier. Sophisticated DSP 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.
  • All PRX700 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 PRX700 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.
  • The amplifier input panel offers stereo inputs with XLR or Ľ 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.
