Perfect for both mobile and fixed installations, the PRX918XLF provides outstanding bass reproduction, making it ideal for live events, music venues, corporate AV, and other applications that demand high-quality, low-frequency reinforcement.
The PRX918XLF is powered by a highly efficient 2,000W (peak) Class D amplifier, ensuring that the subwoofer delivers consistent, distortion-free output even at maximum volume. A next-generation 918SG 18-inch ferrite magnet woofer provides smooth and natural bass, while the FEA-flared port design minimizes air noise and distortion, ensuring clean, accurate sound across the frequency spectrum. The subwoofer features high-quality DACs and ADCs that ensure near-lossless audio conversion, with a total harmonic distortion (THD) rating of less than 32 dB, virtually eliminating system noise. The subwoofer's low-noise, low-distortion gain staging design ensures optimal performance, whether the system is operating at high or low volumes.
With a frequency range of 35 Hz to 92 Hz (±3 dB) and a maximum SPL of 134 dB, the PRX918XLF delivers deep, controlled bass that complements full-range loudspeakers. The subwoofer is designed with advanced DSP, which is fully accessible via the onboard LCD screen or through the JBL Pro Connect app. The DSP suite includes a 6-band parametric EQ for detailed system tuning, along with a low-pass filter and 20ms of delay for precise system alignment. The JBL Pro Connect app provides full control of the subwoofer's settings, allowing users to easily manage up to 10 connected speakers with Bluetooth Low Energy (BLE) functionality. App-exclusive features such as speaker snapshots and grouping make it easy to adjust settings for optimal performance in any environment.
The PRX918XLF's enclosure is made from durable 18mm plywood and is coated in JBL's rugged DuraFlex finish, which provides protection against wear and tear while maintaining an aesthetically pleasing appearance. The cabinet's optimized bracing smooths out low-frequency response, ensuring minimal distortion. The subwoofer also features a quiet, fanless operation that ensures optimal performance without unwanted noise. The two side handles make transportation easy, and the M20 pole cup allows for simple mounting with full-range loudspeakers. With its robust construction and user-friendly design, the PRX918XLF is built to withstand the rigors of both touring and permanent installations.
Whether you're pairing the PRX918XLF with other JBL loudspeakers or using it on its own, this subwoofer is engineered to provide powerful and precise bass, ensuring that every performance reaches its full potential.
