The JBL SP125S is a dual 15-inch passive subwoofer engineered for precise, musical low-frequency reinforcement in professional PA systems. Featuring two JBL 2226 transducers, it delivers tight, controlled bass with excellent definition and fast transient response across a 40–900 Hz operating range. With 100 dB sensitivity (1 W/1 m) and a calculated 137 dB max SPL, it provides generous headroom for dynamic programme material while maintaining clarity and punch. Rated at 1200 W RMS, the SP125S can be run in parallel at 4 ohms from a single amplifier channel or driven discretely per transducer for alignment, cardioid arrays and advanced system optimisation.
The rugged, touring-grade cabinet measures 572 x 1137 x 572 mm and weighs 49.9 kg, striking a balance between durability, output and a manageable footprint for both mobile rigs and fixed installations. Seamless integration with professional system processors and quality full-range tops ensures consistent, repeatable performance that scales from compact setups to larger arrays. A dependable choice for live music venues, clubs, corporate events and performance spaces where accurate low end, strong output and tight control are essential.
