The JBL SRX715 is a lightweight, high‑output passive 15‑inch loudspeaker commonly used in live sound. These speakers offer strong performance in a compact, easy-to-move and set up form factor. It uses JBL’s Differential Drive 15‑inch woofer and a neodymium 3‑inch compression driver on a 75° x 50° horn, giving it punchy lows and clear highs while keeping the cabinet weight around 48 pounds. The speaker can run in either passive or bi‑amp mode using a rear‑panel switch, and its dual‑angle pole mount lets you aim coverage straight ahead or with a 10° downward tilt. With a power rating of 800W continuous and a peak output of up to 131 dB, it works well as a main speaker over subs or as a high‑performance satellite in larger rigs, all housed in a durable birch plywood cabinet built for professional use.
