JBL PRX918XLF 2000-Watt 18-Inch Portable Powered PA System Subwoofer


JBL PRX918XLF 2000-Watt 18-Inch Portable Powered PA System Subwoofer


Manufacturer's Description

The JBL PRX918XLF, part of the JBL PRX900 Series powered loudspeakers and subwoofers, takes professional portable
PA performance to a new level with advanced acoustics, comprehensive DSP, unrivaled power performance and durability, and complete BLE control via the JBL Pro Connect app.

FEATURES All-New Acoustic Designs

From cone to cabinet, the PRX915XLF is designed for advanced acoustic performance. A next-generation 915SG 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 2,000W (peak) Class D power amps, the PRX915XLF 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 PRX915XLF’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 PRX915XLF 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 PRX915XLF 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.
