Applications:
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 2278G 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 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.
Truly an amazing speaker that has enough low end for nearly any venue.<br /> This thing really does thump and does it clean! I have run two of these things for 6 hours straight at 3/4 volume without any problem and with minimal heat. In a school gym application these things will rattle the air ducts and walls around the gym. Compared to other subs in its class, the prx is pretty light weight and very durable when its comes to it being road worthy. I recommend this sub to anyone who wants something that will run all night hard without any problems. JBL knocked this one out of the park!
