JBL VTX-B35 Triple 15-inch Flyable Cardioid Subwoofer

The JBL VTX B35 is engineered for professionals who need controlled low-frequency performance in spaces where conventional cardioid subwoofer arrays are difficult to deploy. Purpose-built for the VTX Series, B35 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 dedicated Crown I-Tech HD amplifier channels and 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, rigging capacity, or architectural constraints limit traditional cardioid approaches.

B35 is designed to work naturally within VTX Series while giving users more ways to solve low-frequency deployment challenges. The flyable B35 is mechanically compatible with VTX A12, enabling clean mixed arrays with A12 suspended below B35 without adapter frames. It is also compatible with A12 rigging accessories including the A12 Array Frame MKII and Suspension Bar, supporting flown, standalone, and hybrid configurations across touring and installed applications. For ground-stacked only systems, or fixed installations , the B35G retains the same acoustic design, amplifier presets, and performance characteristics in a streamlined enclosure without touring flyware.

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, the B35 adds a focused, flexible low-frequency control to the VTX ecosystem. From major festival stages and arena deployments to under-stage placement and fixed installations with limited depth or sightline restrictions, B35 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.
