What JBL Says...

The JBL PRX800 series is the most advanced PA in its class. Wi-Fi technology and sophisticated DSP give you complete control over system tuning and performance via the free PRX Connect app. An efficient 1500-watt class-D amplifier and patented JBL Differential Drive® technology provide best-in-class power and reduced weight. And the rugged all-wood cabinets feature a redesigned input panel and universal power supply for easy, reliable operation worldwide. Designed to deliver legendary JBL sound for bands, DJs and more, PRX800 represents the next generation in smart live sound reinforcement.

Compact and Versatile

The PRX818XLF 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 PRX818XLF performs with exceptional efficiency and control. The subs are stackable and light-weight, 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.

Quality Components

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, 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.

Built to Last

All PRX800 cabinets are built from 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. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each.

Practical Routing

The amplifier input panel offers XLR or ¼ inch jack compatibility and a sensitivity switch provides extra flexibility, making it possible to connect literally any sound source without using a mixer. Signal present and overload lights indicate the system status and assist in setting the optimum level, via the level control knob.

Complete Wireless Control with the PRX Connect App

PRX800 is the first PA system in its class to feature complete wireless control via Wi-Fi. The PRX Connect mobile app for iOS and Android connects wirelessly to every speaker, offering full control over the powerful built-in DSP. Set up, configure and optimize the performance of your live sound system—faster than ever before. Walk around the venue during sound check and fine-tune your speakers to sound better as a system. Use the 8-band EQ, speaker delay, mute, gain and more to make sure your audience hears great sound from every corner of the room. It’s easy to configure shows offline and save presets. You can even find any connected speaker instantly with the useful Locator function.

Powerful JBL Sound, Compact Design

With integrated 1500-watt Class-D power amplifiers, PRX800 is the most powerful, efficient system in its class. Patented JBL Differential Drive™ woofer technology reduces magnet mass while increasing power handling, making PRX800 a remarkably lightweight system capable of delivering clear, pristine audio at extraordinarily high volumes.

Tour-Proven Reliability 

We designed the PRX800 series to perform flawlessly—even on the toughest tours. PRX800 speakers utilize the finest construction materials, including durable wooden cabinets, tour-proven DuraFlex™ finish and dent-resistant 16-gauge grilles. And comprehensive testing—including the famous JBL 100-hour power test—ensures reliability in any environment.

Industry-Leading HARMAN Technology

The PRX800 series combines technology from HARMAN’s industry-leading live sound brands to deliver unprecedented performance. The electronics and input panel are derived from top-tier Crown DSP and user interface technologies. dbx Type IV™ limiting eases the system back to a safe level when any frequency band is in limit, ensuring that the sound is clear, accurate and uncompressed—even at high volume.

Flexibility for Any Gig

The PRX800 series delivers versatility for any performance environment. A flexible interface and universal power supply give you complete control over your setup anywhere worldwide, with XLR, 1/4” and RCA inputs alongside multiple professional outputs. And because all JBL speakers feature the same legendary sound quality, PRX800 can be used with other JBL systems.

Proven JBL Quality

The world’s top artists and venues trust JBL to deliver incredible sound. That’s because over the past 70 years, we’ve invested more into R&D than any other speaker company. PRX800 features innovative components like a new variable-speed fan that activates only when needed for ultra-quiet operation. And the speakers are tuned for flat frequency response and smooth off-axis behaviour to ensure pristine sound throughout the venue.
