JBL PRX818XLFW 18-Inch Powered Subwoofer
JBL PRX818XLW 18-Inch Powered Subwoofer
The JBL PRX818XLFW is a self-powered extended low-frequency subwoofer system. Featuring a JBL 18-inch woofer powered by a 1500-watt class-D amplifier, PRX818XLFW delivers incredible output in a lightweight and compact form factor.
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 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 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 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 1/4 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.
