SRX910LA BP Base Plate for SRX910LA Line Array Column Speaker

The SRX910LA BP is a base plate that lets SRX910LA arrays ground stack on compatible subwoofers, scaffolding, stages, or carts instead of flying. A standard M20 threaded pole mount connects to any subwoofer built for it, including the SRX928S, using the included M20 screw. A rear angle selection bar adjusts the array's tilt from -15 to +5 degrees, so the coverage pattern can be aimed at the crowd rather than the ceiling.

For installations where the array needs to stay in one spot permanently, three M10 through-holes let it bolt directly to a stage, wall, or custom structure. Built from high-grade steel with an anti-corrosion coating and finished in black powder coat, the base plate is rated for up to 4 SRX910LA cabinets at its maximum load and 2 at the recommended safe limit. Load conditions and configuration guidance are available through the JBL Line Array Calculator 3 software for anyone planning a ground-stacked system.
