Deliver room-shaking, controlled low end wherever you need it most. The JBL Professional PRX918XLF powered 18-inch subwoofer combines class-leading power and advanced DSP to give audio professionals precise, reliable bass for live sound, corporate AV and monitoring environments. Built around a next-generation 18-inch driver and an efficient Class D amplifier (1,000W RMS, 2,000W peak), the PRX918XLF delivers up to 134 dB SPL and clean extension down to 30 Hz so music, paging and low-frequency alerts remain clear and impactful.

The 18mm birch cabinet with optimized bracing and FEA flared port minimizes air noise and stands up to the rigors of touring and rental use. Beyond live events, this subwoofer is equally useful in security and surveillance or control-room monitoring applications where accurate bass reproduction supports alerts and voice intelligibility.
