Product Overview
The PRX815XLF 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 PRX815XLF performs with exceptional efficiency and control. The subs are stackable and lightweight, ensuring quick setups and tear-downs. Due to their rugged construction, they are perfect for AV rental inventories. With the 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. PRX800 subwoofers feature a standard M20 threaded pole cup that can accept most modern subwoofer-mounted speaker poles. The PRX815XLF offers remote Wi-Fi control of onboard DSP EQ parameters. Boasts a powerful 2278G Differential Drive® dual voice-coil and magnetic gap woofer driven by a 1500W 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 PRX800 cabinets are built from 18 mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints, and 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. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each. The amplifier input panel offers XLR or ¼ inch jack compatibility. A user-selectable crossover ensures a smooth transition to a 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.
Applications
- The PRX818XLFW 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 PRX818XLFW 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 PRX818XLFW is a high performance self-powered subwoofer system with remote Wi-Fi control of onboard DSP EQ parameters. The PRX818XLFW 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 PRX800 cabinets are built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. All PRX800 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" 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 viathe level control knob.
