1. About

The JBL BRX325SP DDEK is a powered line array subwoofer designed to anchor modular JBL line array systems. As part of JBL’s BRX300 series, it combines built‑in amplification and DSP with rugged portability. This unit handles the low end (bass) while providing power and control to full‑range array “top” speakers (such as the BRX308‑LA). Its modular design allows you to build scalable sound systems for concerts, events, corporate setups, or houses of worship. With its plug‑and‑play DSP management, it simplifies setup without compromising sonic performance.
