The JBL VTX B1 GND Ground Stack Accessory is a universal outrigger system engineered to improve the safety and stability of ground-stacked VTX subwoofer configurations. Specifically designed for use with the VTX B15 and VTX B18 models, this accessory is an essential addition when creating reliable stacks of multiple subwoofers or when integrating full-range VTX loudspeakers above supported subwoofer bases.
Constructed from high-grade steel with an anti-corrosion coating and finished in black powder coat, the VTX B1 GND provides durability, longevity, and professional aesthetics for both touring and permanent installations. By connecting directly to the subwoofer’s integral rigging hardware, it expands the overall footprint of the system, significantly improving stability without adding unnecessary bulk.
The four-part design is lightweight, compact, and optimized for transport, easily fitting into standard road cases. Each outrigger weighs just 1.2 pounds, with the full set totaling 4.8 pounds, making handling and setup straightforward while maintaining robust structural performance. For further convenience and safety, ground stack parameters and mechanical load calculations are supported through JBL’s LAC-3 simulation software, ensuring precise and reliable system configuration every time.
Whether deployed for rental, touring, or fixed installations, the JBL VTX B1 GND Ground Stack Accessory provides peace of mind, allowing AV professionals to confidently build larger, more complex stacks while maintaining the integrity and safety of their VTX subwoofer systems.
