JBL VRX918S-WH 15 in Two Way Stage Monitor

JBL VRX918S-WH 18" High Power Flying Subwoofer

The VRX918S-WH is engineered for gigging musicians and live sound engineers who demand authoritative sub-bass that holds up on any stage. Its front-loaded, vented design delivers commanding low-frequency punch with the tight control and fast transient response that keeps your bottom end locked in during performances and monitor mixes, whether you're running a full rig or flying this sub as part of a larger system.

Output & Frequency Response

This unit punches out 130 dB peak SPL with 800 W continuous / 1600 W program / 3200 W peak power handling—enough authoritative low-end presence to cut through loud stage environments and feel right in the pocket. The 34 Hz – 220 Hz (±3 dB) frequency response with 31 Hz – 220 Hz at -10 dB delivers tight, articulate bass that integrates seamlessly with your mains using the recommended 80 Hz crossover point.

Build & Durability

Built from 18 mm, 13-ply birch plywood with heavy internal bracing, this enclosure stands up to the road—panel resonance stays down, structural integrity stays solid through repeated load-in and load-out cycles. The powder-coated white 16-gauge perforated steel grille with acoustical foam backing shrugs off impact, and the DuraFlex finish keeps the cabinet looking right even after months of touring.
