JBL VRX918S-WH 15 in Two Way Stage Monitor

JBL VRX918S-WH 18" High Power Flying Subwoofer

The VRX918S-WH is a heavyweight subwoofer engineered for touring sound systems and large-venue installations where extended low-frequency response and output headroom are non-negotiable. Its front-loaded, vented design delivers commanding sub-bass extension while maintaining the tight control and fast transient response required for live reinforcement and monitor mixing in professional environments.

Output & Frequency Response

This unit produces 130 dB peak SPL with 800 W continuous / 1600 W program / 3200 W peak power handling, translating to authoritative low-end punch that cuts through loud stage environments. The 34 Hz – 220 Hz (±3 dB) frequency response with 31 Hz – 220 Hz at -10 dB ensures tight, articulate bass that integrates cleanly with main speakers using the recommended 80 Hz crossover point.

Build & Durability

Constructed from 18 mm, 13-ply birch plywood with heavy internal bracing, the enclosure resists panel resonance and maintains structural integrity under road use. The powder-coated white 16-gauge perforated steel grille with acoustical foam backing provides impact protection while the DuraFlex finish handles repeated setup and breakdown cycles without cosmetic degradation.
