JBL Professional Mounting Plate for Loudspeaker, Subwoofer

The SRX910LA Base Plate is a universal adapter frame that enables SRX910LA arrays to be ground stacked on top of compatible subwoofers or support structures such as stages, scaffolding, or carts. Using the included M20 screw, the SRX910LA BP connects to any supported subwoofer equipped with a standard M20 pole mount adapter, such as the SRX928S. The rear angle selection bar allows for angles ranging from -15 to +5 degrees. The three included M10 through-holes can be used to permanently attach an SRX910LA array to other support structures. Configurations and load conditions for using the SRX910LA BP can be obtained using JBL Line Array Calculator 3 software. For more information about the base plate and use cases refer to the SRX900 Series Rigging Manual.
