The VTX A12 Base Plate accessory is a universal adapter frame that enables VTX A12 arrays to be ground stacked on top of compatible subwoofers or support structures such as stages, scaffolding, or carts. Using the included M20 knob-screws, the VTX A12 BP attaches directly to the bottom of an A12 array, and then to top-mounted M20 plates on the VTX B28 subwoofer. The rear angle selection bar can be set for angles between -15 degrees and +5 degrees. When not used with B28 subwoofers, the A12 BP’s M10 through-holes can be used to permanently attach an A12 array to other support structures. Configurations and load conditions for using the VTX A12 BP can be obtained using JBL LAC-3 prediction software application.
