PRX918XLF [Open Box]

The JBL PRX918XLF is a powered 18-inch subwoofer built to anchor the low end of a PRX900 Series system or any full-range rig that needs serious bass extension. A next-generation 18-inch driver, powered by an ultra-efficient Class D amplifier, delivers up to 2,000W peak output (1,000W RMS) with a max SPL of 134 dB, and an FEA flared port design reduces air noise and distortion at high output.

Its DSP package includes a 6-band parametric EQ, a lowpass filter, and 20ms of delay, all accessible through an onboard LCD or the JBL Pro Connect app, which also extends control to up to 10 speakers at once and integrates with JBL EON ONE MK2, PRX ONE, and EON700 systems. An 18mm birch cabinet with optimized internal bracing improves both low-frequency response and long-term durability, and quiet fanless operation keeps the subwoofer running without added noise. Backed by a seven-year warranty, the PRX918XLF suits touring bands, rental houses, and venues that need a compact but powerful subwoofer.
