JBL PRX818XLF
18” Self-Powered Extended Low-Frequency Subwoofer System with Wi-Fi

The JBL PRX818XLF is a self-powered extended low-frequency subwoofer system. Featuring a JBL 18-inch woofer powered by a 1500-watt class-D amplifier, PRX818XLF delivers incredible output in a lightweight and compact form factor.

Features

  • Built-in Wi-Fi for wireless control of your system from anywhere in the venue
  • Free PRX Connect mobile app for iOS and Android provides wireless control over volume levels, 8-band parametric EQ and up to 50ms of speaker delay to fine-tune your sound
  • Class-leading 1500-watt amplifier delivers ample power to fill your venue
  • JBL Differential Drive® transducers for higher SPL in a lightweight design
  • Next-generation JBL neodymium compression drivers
  • Redesigned Crown input technology, including XLR, 1/4” and RCA inputs plus XLR loop-through
  • Intelligent variable-speed fan activates only when needed to reduce noise
  • Updated tuning delivers flat frequency response and smooth off-axis behavior
  • Durable wooden cabinets, tour-proven DuraFlex™ finish and dent-resistant 16-gauge grilles
  • Universal power supply for worldwide compatibility
  • dbx Type IV™ limiting ensures clear, accurate sound at high volumes
  • Brutal testing regimen—including the famous JBL 100-hour power test—ensures reliable performance Applications

Applications

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 set-ups 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 PRX818XLF is a high-performance self-powered subwoofer system with remote Wi-Fi control of onboard DSP EQ parameters. The PRX818XLF is comprised of a powerful 2278G 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 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 dent-resistant 16 gauge steel and handles are made from light-weight 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 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.
