HARMAN Professional Solutions, the global leader in audio, video, control, and lighting systems, today announced the expansion of the JBL Professional VTX Series with the introduction of the VTX B35 and VTX B35G compact cardioid subwoofers. Designed to deliver controlled low-frequency coverage in applications where traditional cardioid subwoofer arrays are difficult to deploy, the new subwoofers combine low-frequency control with a compact, deployment-friendly form factor. Mechanically compatible with VTX A12, the VTX B35 enables clean mixed-array configurations while expanding the VTX Series ecosystem with flexible low-frequency solutions for touring and fixed installation applications.
“B35 gives system designers and rental providers a more practical way to achieve low-frequency control in environments where conventional cardioid arrays are difficult to deploy,” said George Georgallis, Director of Product Management, Performance Audio at HARMAN Professional Solutions. “Additionally, the ability to fly B35 directly above VTX A12 arrays provides new deployment flexibility for A12 systems, particularly in applications where space for ground-stacked subwoofers is limited or unavailable.”
VTX B35 integrates cardioid behaviour into a single-enclosure design that reduces rearward energy while keeping low-frequency coverage focused on the audience. By eliminating the need for additional rear-facing cabinets, complex array spacing, or field-built subwoofer configurations, the B35 simplifies deployment and provides a practical solution for productions and installations where space, trim height, rigging capacity, or architectural constraints limit traditional cardioid subwoofer approaches.
At the core of the system are three JBL Differential Drive 15-inch woofers arranged in a front-rear configuration, with two forward-facing drivers and one rear-facing driver. Each section is powered independently via dedicated amplifier channels and optimised presets, resulting in predictable cardioid directivity. With extension down to 32 Hz and a high output-to-size ratio, the VTX B35 delivers powerful low-frequency performance while maintaining a compact footprint suited for touring productions, festivals, arenas, houses of worship, performance venues, and fixed installations.
The VTX B35 is mechanically compatible with VTX A12 line arrays, enabling clean mixed-array configurations with A12 suspended directly below B35 without requiring adapter frames. The B35 also integrates with the VTX A12 rigging accessories, including the new A12 Array Frame and current A12 Suspension Bar, supporting flown, standalone, and hybrid deployment configurations across touring and installed applications. The B35G provides the same acoustic design and performance, but omits touring-style rigging, making it well-suited for ground-stacked-only applications or fixed installations.
The VTX B35 Series integrates with the complete JBL software ecosystem, including Venue Synthesis, Array Link, and Performance Manager, enabling system designers to streamline prediction, deployment, optimisation, and system control workflows within a single ecosystem. Integrated subwoofer array tools, including the Electronic Delay Steering (EDS) calculator, enable rapid optimisation of large, distributed subwoofer arrays.
