Description
JBL VRX918S 18" High Power Flying Subwoofer
The VRX918S delivers earth-shaking low-end punch with remarkable articulation and control, responding with crystalline clarity down to the deepest frequencies. The 18-inch driver translates every nuance of your mix with visceral impact, giving you the ability to feel rather than just hear the bottom end across electronic music, hip-hop, reggae, and full-range live sound applications. The flying subwoofer design offers unparalleled flexibility in placement and coverage, letting you shape your sonic landscape with precision while maintaining the kind of tight, musical low-end response that makes mixing and monitoring a genuinely effective experience.
Driver & Enclosure Design
The 18" woofer features a 2268H neodymium magnet with patented Differential Drive technology, housed in a front-loaded, vented enclosure constructed from 18 mm, 13-ply birch plywood and finished in JBL's DuraFlex coating. A large port area is engineered to minimize distortion while a 16 gauge steel grille provides durable protection without compromising acoustic performance.
Power & Acoustic Performance
The VRX918S handles 800 W / 1600 W / 3200 W across three power modes, achieving a System Maximum SPL of 130 dB peak with 95 dB SPL sensitivity at 8 ohms nominal impedance. Frequency response spans 31 Hz – 220 Hz with a usable frequency range of 34 Hz – 220 Hz, delivering the low-end definition and impact demanded by touring and installed sound systems.

Frequently Asked Questions
What does flying subwoofer design mean, and why does it matter for live sound?
Flying design uses integral rigging hardware to suspend the sub from above or rig it into truss and line-array systems, letting you position bass coverage wherever the venue demands without taking up stage or floor space. The VRX918S is compatible with VRX932LA line-arrays and optional array frames, giving you placement flexibility and precise control over where the low-end hits the room.
How does the VRX918S compare to its competitors like the QSC KS212C or EV ETX-18SP?
All three are professional touring subs, but the VRX918S emphasizes articulate, controlled low-end down to 34 Hz with minimal distortion via Differential Drive technology and a large-port vented design, making it particularly strong for electronic music and hip-hop where clarity matters as much as punch. Comparison specs and tuning preferences should be verified against the competing models' frequency response curves and intended venue size.
What power modes does it offer, and how do I choose between them?
The VRX918S operates in three selectable modes: 800 W, 1600 W, or 3200 W, all controlled by a recessed external switch. Choose based on your venue size, available amplification, and desired SPL; touring systems typically run it at 1600 W or higher to maximize the 130 dB peak capability across large spaces.
What are the physical dimensions and weight, and will it fit my rig?
The VRX918S measures 508 mm H x 597 mm W x 749 mm D and weighs 81 lb, designed to fly or deploy in touring rigs with 13-ply birch plywood construction and a 16 gauge steel grille for road durability. Verify that your rigging points, transport cases, and amplifier rack match its impedance (8 ohms nominal) and power demand before purchase.
What crossover settings do you recommend, and what is it not designed for?
JBL recommends an 80 Hz crossover with 24 dB/octave high-pass and low-pass filtering for optimal integration with main speakers. The VRX918S is purpose-built for touring PA and large-venue live sound; it is not suitable for home listening, small-venue monitoring, or nearfield studio work where room size and acoustic control make it impractical.
