The PRX918XLF subwoofer, part of the JBL PRX900 Series powered loudspeakers and subwoofers, elevates professional portable PA performance with superior acoustics, full DSP, unrivalled power performance and durability, and total BLE control via the JBL Pro Connect app.
This 18-inch powered subwoofer is designed to exploit JBL's most cutting-edge acoustic advances fully. At maximum volume, a next-generation speaker powered by an ultra-efficient Class D amplifier offers crisp, defined bass with smooth low-frequency extension.
The PRX918XLF's class-leading DSP package includes a 6-band parametric EQ for system tuning and subtle tone control, as well as a lowpass filter and 20ms delay, which can be accessed via the onboard LCD or the JBL Pro Connect app.
The JBL Pro Connect app gives you comprehensive hardware and DSP control over up to ten speakers; it integrates with JBL AEON ONE MK2, PRX ONE, and EON700 systems, and it gives you access to app-only features like speaker snapshots and grouping.
The PRX918XLF is built to resist the rigours of the road, with an 18mm birch cabinet and optimised bracing for smooth low-frequency response and increased longevity. Like every other JBL product, everything is strengthened by industry-leading test and validation methods and guaranteed by a seven-year warranty.
The PRX900 Series is an adaptable solution for DJs and bands, music venues, rental houses, corporate A/V providers, and anybody else who need long-lasting professional systems that offer powerful, room-filling sound in any portable or installed setting.
Acoustic Designs
The PRX918XLF is engineered for superior acoustic performance from the cone to the cabinet. A ferrite magnet in the 918SG woofer produces a smooth, natural bass tone, while an FEA flared port design eliminates air noise and distortion. All this adds to a clear, accurate, and powerful sound at any volume.
Performance
PRX900 systems easily support extensive performance areas with high power and performance requirements. The PRX918XLF, powered by 2,000W (peak) Class D power amps, delivers bass with clarity and definition at maximum volume. Inductors with excellent power efficiency and low total harmonic distortion are used, and low-noise, low-distortion input gain staging optimises range and headroom for a wide variety of gain requirements. High-quality DACs and ADCs provide near-lossless audio conversion. System noise is nearly nonexistent, with a full-bandwidth CMRR (Common Mode Rejection Ratio) of more than 55 dB and a THD (total harmonic distortion) rating of 32 dB.
Class-Leading DSP
The PRX918XLF's class-leading DSP package includes a 6-band parametric EQ for system tuning and subtle tone control, as well as a lowpass filter and a 20ms delay, which can be accessed via the onboard LCD or the JBL Pro Connect app.
Scalable and adaptable
Combine PRX900 Series loudspeakers and subwoofers in various configurations to fulfil the demands of mobile and fixed installations. M20 pole cups are used in subwoofers.
Pro Connect
The JBL Pro Connect app includes Bluetooth Low Energy (BLE) technology for system control of up to ten speakers and line integration with JBL AEON ONE MK2, PRX ONE, and EON700 loudspeakers—access entire DSP operations from the app anytime, including app-only features such as speaker snapshots and groupings.
Tough and roadworthy
The components of the PRX900 are contained in sturdy, lightweight cabinets that maximise acoustic performance and longevity. The PRX918XLF enclosure is made of 18mm birch, and features improved bracing to smooth out low-frequency response. Duraflex coatings are incredibly durable.
JBL Warranty
The PRX915, like all JBL products, goes through an industry-leading 100-hour stress test of all components to ensure systems function above expectations in real-world circumstances. It's so dependable that it comes with a seven-year warranty, which is unparalleled.
