Audio professionals looking to ground-stack a SRX900 Series line array will need the JBL Base Plate for SRX906LA Arrays. The base plate is a universal adapter frame that allows up to six SRX906LA arrays to be ground stacked atop of compatible subwoofers or support structures such as scaffolding, stages, or carts.

The rear angle selection bar allows for angles ranging from -15 to +5°. For smaller setups, the base plate is compatible with the JBL pole mount adapter, which connects to the SRX918S or SRX928S subwoofers via the M20 connector. The pole mount configuration can support up to two SRX906LA arrays. Additionally, the three included M10 through-holes can be used to permanently attach an SRX906LA array to other support structures.
