11 - BASE PLATES
The SRX06LA BP Base Plate and the SRX910LA BP Base Plate are universal adapter frames that enable arrays to be ground stacked on
top of compatible subwoofers or support structures such as stages, scaffolding, or carts. Using the included M20 screw, a base plate
connects to supported subwoofers equipped with a standard M20 pole mount adapter, such as the SRX918S or the SRX928S. The base
plate attaches directly to the bottom of the cabinets, and the rear angle selection bar allows for angles ranging from -15 to +5 degrees.
When not used with subwoofers, M10 through-holes can be used to permanently attach an array to other support structures. The base
plates include one 50 mm wide (2 in) notch on each side for easy use with ratchet straps. Configurations and load conditions for using
a Base Plate can be obtained using JBL’s LAC-3 software
