The JBL PRX915XLF is a professional powered 15-inch subwoofer from the acclaimed PRX900 Series, engineered to deliver exceptional portable PA performance for DJs, bands, music venues, rental houses, and corporate A/V providers. This subwoofer combines cutting-edge acoustics, robust DSP, and a lightweight, efficient 2,000-watt peak (1,000W RMS) Class D amplifier to produce clear, defined bass with smooth low-frequency extension, even at maximum volume. With a frequency response of 36 Hz–98 Hz (-10 dB) and a maximum SPL of 131 dB, the PRX915XLF ensures room-filling sound in any setting, whether portable or installed.

Built with a high-performance 915SG 15-inch ferrite magnet woofer, this subwoofer offers low-noise, low-distortion audio thanks to its innovative gain staging design. The comprehensive DSP suite—accessible via an onboard color LCD or the JBL Pro Connect app—includes a 6-band parametric EQ, lowpass filter, 20ms delay, Automatic Feedback Suppression, and a system limiter, empowering users with precise tuning and tonal control. The JBL Pro Connect app enhances functionality with Bluetooth Low Energy (BLE) networking, enabling full hardware and DSP control of up to 10 speakers, integration with JBL EON ONE MK2, PRX ONE, and EON700 systems, and exclusive features like speaker snapshots and grouping.

Designed for durability, the PRX915XLF is housed in an 18mm birch cabinet with optimized internal bracing for improved low-frequency response and resilience on the road. It features two balanced XLR combo inputs, two XLR pass-through outputs, an M20 pole mount, and dual handles for easy transport. At just 28.6 kg (63 lbs), this fanless, quiet-operating subwoofer is reinforced by JBL’s industry-leading testing protocols, ensuring reliability for professional use. With selectable crossover frequencies (80 Hz, 100 Hz, 120 Hz) and optimized presets, it pairs seamlessly with full-range speakers for a cohesive, time-aligned audio experience.
