Professional portable PA systems reach new heights with the PRX915XLF subwoofer from JBL's acclaimed PRX900 Series. This 15-inch powered subwoofer combines advanced acoustic engineering with comprehensive DSP processing and complete Bluetooth Low Energy control through the JBL Pro Connect app. Built for DJs, bands, music venues, rental companies and corporate A/V providers, the PRX900 series offers versatile solutions for both portable and installed applications where powerful, room-filling sound is essential.
At the heart of the PRX915XLF sits a high-performance driver powered by an ultra-efficient 2,000-watt Class D amplifier, producing clear, defined bass with smooth low-frequency extension even at maximum volume. The unit's class-leading DSP package can be accessed via the onboard LCD display or through the JBL Pro Connect app, featuring 6-band parametric EQ for precise system tuning, plus lowpass filtering and 20ms delay capabilities. The Pro Connect app provides complete hardware and DSP control for up to 10 speakers and integrates seamlessly with JBL EON ONE MK2, PRX ONE and EON700 systems.
Durability remains paramount with the PRX915XLF's construction featuring an 18mm birch cabinet with optimised internal bracing for enhanced low-frequency response and road-ready resilience. JBL's industry-leading testing and validation protocols back every component, supported by a comprehensive seven-year warranty. Recent firmware updates through JBL Pro Connect V1.8 have improved metering accuracy, enhanced pass-through filtering, refined gain staging, and added new connectivity features including sleep mode control and updated system presets.
