APPLICATIONS
The PRX815XLFW 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 PRX815XLFW 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 an 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 PRX815XLFW is a high-performance self-powered subwoofer system with remote Wi-Fi control of onboard DSP EQ parameters. The PRX815XLFW is comprised of a powerful 2275H Differential Drive® dual voice-coil and magnetic gap, the woofer is 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 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.
