JBL Base Plate for SRX910LA Line Array Speaker

The JBL JBL-P3238MX is a base plate made for SRX910LA line array speakers. It forms a secure link between the array and any subwoofer or support that offers an M20 threaded pole, allowing you to build a ground-stacked system in minutes. The supplied M20 screw fits subwoofers like the SRX928S, locking the plate in place and creating a stable platform for up to six SRX910LA cabinets.

A rear angle selection bar lets you set tilt from minus 15 to plus 5 degrees, so you can direct sound toward floor-level listeners or balcony seats without extra rigging. Because the plate is built from high-grade steel, it stands up to repeated load-ins and keeps the array rigid even at high output.

Three integrated M10 through holes give installers the option of a more permanent attachment to stages, carts, or scaffolding. When you need precise predictions before the show, the plate appears in JBL Line Array Calculator 3 software, making it easy to confirm load limits and coverage angles.

From corporate events and portable church services to small theaters and club gigs, the JBL-P3238MX streamlines setup, maintains safety, and helps you deliver consistent coverage every night.
