JBL IRX115S Powered 15inch Portable PA Subwoofer

Professional sound reinforcement gets a powerful new foundation with the JBL IRX115S powered subwoofer, engineered to shake rooms with bass response extending down to an impressive 35 Hz. This 15-inch powerhouse represents the latest addition to JBL's cost-conscious IRX series, combining over 70 years of speaker innovation with modern touring technologies to produce 128 dB of deep, authoritative low-end performance. The custom-designed driver features a substantial 3-inch voice coil, while the high-efficiency amplifier provides 1,300 watts of power with built-in driver protection.

Smart engineering makes the IRX115S remarkably versatile for professional applications. Selectable crossover points at 80 Hz, 100 Hz, and 120 Hz allow precise system tuning, particularly when paired with other IRX series loudspeakers, while the polarity switch optimises overall system response. The tuned, ported enclosure design enhances output while minimising unwanted woofer noise, and dual XLR combo inputs with XLR outputs provide flexible connectivity options.

Despite its substantial output capabilities, the IRX115S maintains impressive portability at just 65.3 pounds. The lightweight MDF cabinet features JBL's signature reinforced honeycomb bevel pattern for durability without acoustic compromise, complemented by ergonomic handles for easy transport. Road-tested construction includes a reinforced grille and standard pole mount compatibility, while JBL's rigorous 100-hour stress testing ensures reliability for touring professionals, venue operators, and mobile entertainers who demand consistent performance.
