Description
Audio professionals looking for a powerful, accurate sub bass reproduction will be impressed by the JBL PRX918XLF, a 2000W 18″ powered subwoofer for main PA applications with extensive Bluetooth control over the onboard DSP. Well suited for event halls, bands, DJ systems, clubs, bars, schools, and churches, the subwoofer is optimized for low-frequency sound reinforcement applications. The PRX918XLF can be paired with any full-range speaker, but is designed to match the PRX line of speakers, offering a high-performance self-powered sub/satellite system.
A Class-D amplifier delivers 2000W to the 18″ woofer, which offers a frequency range of 35 Hz to 92 Hz at 134 dB maximum SPL output. The built-in Bluetooth offers wireless control of the system from anywhere in the venue, using the free Pro Connect app for iOS and Android devices. The app controls levels, parametric EQ, user presets, and up to 20ms of user-defined delay to fine-tune your setup. The durable 18mm birch plywood enclosure is coated with an DuraFlex finish and a powder coated steel grille.

All-New Acoustic Design
From cone to cabinet, the PRX918XLF is designed for advanced acoustic performance. A next-generation 918SG woofer with ferrite magnet delivers smooth, natural bass response, and an FEA flared port design reduces air noise and distortion. It all adds up to clean, accurate, powerful sound at any volume.
Power that Performs for You
PRX900 systems effortlessly support large performance spaces with high power and performance needs. Driven by highly efficient 2000W (peak) Class-D power amps, the PRX918XLF delivers bass with clarity and definition at maximum volume. High-quality, high-linearity inductors deliver high power efficiency and low total harmonic distortion. High-quality DACs and ADCs provide near-lossless audio conversion. And with a full-bandwidth CMRR (Common Mode Rejection Ratio) greater than 55 dB and THD (total harmonic distortion) rating of <32 dB, noise is virtually nonexistent.
Dial In Your Sound with Class-Leading DSP
The PRX918XLF’s class-leading DSP package, accessible via onboard LCD or the JBL Pro Connect app, includes 6-band parametric EQ for system tuning and nuanced tonal control, plus lowpass filter and 20ms delay.
Versatile and Scalable
Combine PRX900 Series loudspeakers and subwoofers in a range of configurations to meet the needs of both mobile scenarios and fixed installs. Subwoofers feature M20 pole cups.
Part of the Pro Connect Ecosystem
JBL’s Pro Connect app offers BLE functionality for system control of up to 10 speakers and line integration with JBL EON ONE MK2, PRX ONE, and EON700 loudspeakers. Access full DSP functions anywhere right from the app, including app-only features like speaker snapshots and groupings.
Rugged and Road-Worthy
PRX900 components are housed in strong, lightweight cabinets that maximize both acoustic performance and durability. The PRX918XLF enclosure is built from 18mm birch, with optimized bracing that smooths out low-frequency response. A Duraflex coating provides superior durability.
In It for the Long Haul
Like every JBL product, the PRX918XLF undergoes an industry-leading 100-hour stress test of all components to ensure systems perform beyond expectations in real-world scenarios. It’s so reliable that it’s backed with an unprecedented seven-year warranty.
