Description
JBL VRX918S-WH 18" High Power Flying Subwoofer
The VRX918S-WH is a heavyweight subwoofer engineered to anchor low-end in recording sessions, mix monitoring, and studio tracking where extended sub-bass response and headroom prevent frequency masking and phase issues. Its front-loaded, vented design delivers commanding sub-bass extension while maintaining the tight control and fast transient response required for accurate bass reproduction and precise frequency placement in professional tracking and mixing 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 that reveals mud, phase interaction, and spectral imbalances during critical listening sessions. 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 monitors using the recommended 80 Hz crossover point, letting you hear exactly what's happening in the fundamental and sub-bass ranges.
Build & Durability
Constructed from 18 mm, 13-ply birch plywood with heavy internal bracing, the enclosure resists panel resonance and maintains consistent tonal character across long studio sessions. The powder-coated white 16-gauge perforated steel grille with acoustical foam backing provides impact protection while the DuraFlex finish withstands repeated cable connections, equipment repositioning, and studio workflow without cosmetic degradation.
