The JBL SP125S is a dual 15-inch passive subwoofer built for precise, musical low-frequency reinforcement in professional PA systems. Loaded with two JBL 2226 transducers, it delivers tight, controlled bass with outstanding definition and transient response across a wide 40–900 Hz operating range. With 100 dB sensitivity (1 W/1 m) and a calculated 137 dB maximum SPL, it offers 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 deployment and advanced system optimisation.
The rugged, touring-grade enclosure measures 572 x 1137 x 572 mm and weighs 49.9 kg, balancing durability, output and a manageable footprint for both touring and fixed installation. It integrates seamlessly with professional system processors and quality full-range tops, delivering consistent, repeatable performance that scales from compact rigs 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.
