JBL PRX918XLF Professional 18" 2000W Powered Subwoofer with Bluetooth Control

The JBL PRX918XLF is a road-tough professional powered subwoofer built to deliver precise, high-impact low end for modern live sound PA rigs. A next-generation 918SG 18-inch subwoofer driver in an 18 mm birch enclosure is driven by a 2000W Class-D amplifier (1000W RMS), providing fast transient response and confident headroom. JBL’s FEA-flared porting minimizes turbulence and distortion, while onboard DSP with LCD control and Bluetooth DSP control via the JBL Pro Connect app puts advanced tuning at your fingertips. Selectable low-pass filters (80/100/120 Hz), polarity, delay, and six-band parametric EQ make it easy to integrate with tops for houses of worship, theatre, and mobile DJ systems.

Engineered for reliability, the PRX918XLF achieves a max SPL 134 dB with consistent output and ultra-low system latency (<1 ms). Frequency performance is voiced for real-world punch—30–110 Hz (-10 dB) with a frequency range 35–92 Hz (-3 dB)—delivering extended, musical bass that stays controlled at volume. Connectivity is straightforward: two balanced combo inputs with two XLR pass-throughs streamline expansion. Physical details are tour-ready too: dual side handles, an M20 pole cup for sub-satellite setups, powder-coated steel grille, and a durable 18mm birch cabinet with rugged coating. Dimensions are 27.3 × 23.3 × 25.7 in (H×W×D); net weight is 89.7 lb.

From corporate AV and houses of worship to mobile production, the PRX918XLF scales cleanly in arrays or as a single sub, and it interoperates with JBL PRX900 tops for a matched system voice. Quiet, fanless convection cooling, omni coverage, and an industry-leading seven-year warranty round out a sub that’s as dependable as it is powerful.
