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 lightweight ensuring quick setups and teardowns. And due to their rugged construction are perfect for AV rental inventories. With a pole receptacle (that accepts a SS4BK or SS4BK24) on the top panel and integrated stereo passthru this is the most powerful lowfrequency complement to the PRX fullrange systems. The addition of a polarity reverse option further enables system optimization. The PRX815XLFW is a high performance selfpowered subwoofer system with remote WiFi control of onboard DSP EQ parameters. The PRX815XLFW is comprised of a powerful 2275H Differential Drive dual voicecoil and magnetic gap, woofer driven by a 1500 Watt ClassD power amplifier. Sophisticated DSP is at the core of a fully featured input section, providing user selectable crossover 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, lightweight 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 dentresistant 16 gauge steel and handles are made from lightweight glassfilled nylon for added strength and durability. The amplifier input panel offers stereo inputs with XLR or inch jack compatibility. A user selectable crossover ensures a smooth transition to fullrange 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.
