Martin WPC Ground Stack Bar

Martin Audio designed the WPC Ground Stack Bar to provide a secure, efficient solution for deploying Wavefront Precision Compact (WPC) line array elements in ground-stacked configurations. Purpose-built for touring and live sound applications where flying isn't practical or permitted, this essential rigging accessory ensures rapid and reliable setup of WPC arrays atop compatible Martin Audio subwoofers.

Engineered from heavy-duty steel construction, the ground stack bar delivers the structural integrity demanded by professional touring environments. It interfaces seamlessly with the WPC rigging system, allowing technicians to build compact, precisely angled ground-stacked arrays with the same inter-element splay accuracy expected from flown deployments. This ensures consistent coverage and pattern control even in ground-stack scenarios.
