JBL VTX-B28-GND Outrigger System for Ground Stacking B28 Speakers
JBL VTX-B28-GND Outrigger System for Ground Stacking B28 Speakers
The VTX B28 GND is an outrigger accessory used to improve stability in ground stack configurations built on the VTX B28 subwoofer. The B28 GND connects directly to the B28’s integral rigging hardware and enlarges the base footprint of the stack. The B28 GND can be used with B28-only ground stacks of more than four enclosures, or when full-range VTX speakers are stacked on top of B28 subwoofers using one of the supported base plate accessories. The B28 GND enables semi-permanent attachment of B28s to stages, carts, and other support structures, using its M10 through-holes. The two-part design is compact, lightweight, and fits into most standard road cases. Ground stack parameters and mechanical safety of arrays are calculated using JBL’s LAC-3 software.
