The JBL SP125S is a dual 15-inch passive subwoofer engineered for fast, musical low-frequency reinforcement with generous headroom. Twin JBL 2226 transducers deliver a tight, controlled punch across a broad 40–900 Hz operating range, keeping bass precise without masking the mix. With 100 dB sensitivity (1 W/1 m) and a calculated maximum SPL of 137 dB at 1 m, it maintains authority and definition at demanding show levels. A robust 1200 W RMS power handling supports long-duty cycles and dependable day-to-day performance.
System integration is flexible: run both woofers in parallel at 4 ohms from a single amplifier channel, or use the dual 8-ohm inputs for discrete amplification and advanced optimisation. The tour-ready enclosure measures 572 x 1137 x 572 mm and weighs 49.9 kg, combining durability for mobile rigs with neat integration in permanent installs.
Ideal for live music, clubs, corporate events and performance venues, the SP125S provides impactful, controlled low end that complements professional full-range systems.
