The JBL IRX115S powered subwoofer is the latest addition to the IRX Series, delivering exceptional low-frequency performance down to an earth-shaking 35 Hz. Designed for budget-conscious musicians, DJs, presenters, and fitness instructors, this subwoofer extends the depth of portable P.A. systems with legendary JBL sound quality. Drawing on over 70 years of JBL’s professional touring technology, the IRX115S features a custom 15” woofer with a 3” voicecoil, a high-efficiency 1300W amplifier, and a tuned, ported enclosure for a remarkable 128 dB of deep, powerful bass. Weighing just 65.3 pounds, its ultralight, rugged MDF cabinet is built to outperform larger systems while remaining easy to transport.

Engineered for versatility, the IRX115S offers selectable crossover points at 80 Hz, 100 Hz, and 120 Hz, optimized for seamless integration with JBL IRX Series loudspeakers like the IRX108BT and IRX112BT. A polarity switch and built-in settings simplify system tuning in any venue, while the ported design minimizes woofer noise and enhances output. Connectivity is a breeze with two XLR Combo inputs and two XLR outputs, alongside a standard pole mount for flexible setups. The durable enclosure, reinforced with a honeycomb bevel pattern and a tough grille, ensures road-ready reliability—verified by JBL’s rigorous 100-hour stress test.

Perfect sound is effortless with the IRX115S. Pair it with IRX Series P.A.s to unlock Bluetooth streaming, dbx DriveRack feedback suppression, one-touch ducking, and real-world EQ presets. Whether you’re a beginner or a pro, this subwoofer delivers stunning, professional-grade audio in a compact, cost-effective package.
