Product Overview
The JBL PRX918XLF is a powered 18-inch portable subwoofer from the PRX900 Series, built to deliver deep, high-output low frequency beneath PRX900 full-range loudspeakers for live events and portable commercial AV. It combines an 18-inch driver with onboard Class-D amplification and DSP. Bluetooth control simplifies setup for mobile rigs in multi-purpose rooms, all-hands spaces, and stage use.
Product Description
The PRX918XLF integrates amplification, DSP, and protection in a portable subwoofer enclosure, adding deep sub-bass headroom to a PA system. The 18-inch driver provides the most low-frequency extension in the PRX900 powered-sub range. Onboard DSP provides crossover, EQ, and system presets to align the subwoofer with full-range tops, while Bluetooth supports wireless control. A pole socket lets a full-range PRX top mount directly above. For more portable PA options, browse the JBL Professional Powered PA Speakers collection.
