JBL VTX-B35G Triple 15-inch Cardioid Subwoofer

The JBL VTX B35G is engineered for professionals who need controlled low-frequency performance in applications where conventional cardioid subwoofer arrays are difficult to deploy. Purpose-built for the VTX Series, B35G brings fixed cardioid behavior into a compact, single-enclosure design, giving system designers a practical solution to reduce rearward energy, improve stage conditions, and keep low-frequency coverage focused toward the audience.

At the core of the system are three JBL Differential Drive 15-inch woofers arranged in a front-rear configuration. Two forward-facing drivers and one rear-facing driver are powered independently using optimized JBL presets. This integrated architecture produces predictable cardioid directivity without requiring additional rear-facing cabinets, complex spacing calculations, or field-built subwoofer arrays. The result is a low-frequency solution that is easier to specify, faster to deploy, and better suited to applications where available space, deployment space, or architectural constraints limit traditional cardioid approaches.

B35G is designed to work naturally within the VTX Series while giving users more ways to solve low-frequency deployment challenges. Acoustically identical to the flyable B35, it delivers the same performance while replacing touring flyware with 16 M10 Quick Link™ eyebolts for installations. Compatibility with all VTX Series Base Plates enables clean and efficient deployment of ground-stacked applications, supporting both standalone subwoofer configurations and integrated VTX system deployments.

With extension down to 32 Hz, a high output-to-size ratio, optimized presets, simple NL4 wiring, and integration with Venue Synthesis, Array Link, and Performance Manager, B35G adds focused, flexible low-frequency control to the VTX ecosystem. From arena floors and festival grounds to houses of worship, theaters, and fixed installations with limited depth or sightline restrictions, B35G helps deliver the right amount of bass in the right direction, with less energy where it is not needed.

Common Applications

B35 Series is suited for touring productions, festivals, arenas, performance venues, houses of worship, and fixed installations that require directional low-frequency control in a compact footprint. It is especially useful where stage wash, backstage noise, trim height, under-stage height, or architectural constraints make conventional cardioid subwoofer arrays impractical.
