JBL PRX915XLF B-Stock Powered Subwoofer
The PRX915XLF is a compact yet powerful 15-inch powered subwoofer engineered for portable sound systems that demand serious low-end extension without excessive footprint. Its Class D amplifier delivers authoritative bass response while the fanless cooling design keeps the cabinet silent during operation, making it equally suited to live sound reinforcement, DJ setups, and studio monitoring applications.
Amplification & Output
Built-in Class D amplifier rated at 1000W RMS / 2000W Peak powers the 915SG 15-inch woofer with a 3-inch voice coil and ferrite magnet. The system achieves 131 dB SPL peak, providing sufficient headroom for mid-sized venues and outdoor events without distortion at typical operating levels.
Connectivity & Control
Dual balanced combo inputs (XLR/jack) accommodate both XLR and 1/4-inch connections, with 2x XLR pass-through outputs for daisy-chaining additional subwoofers or speakers. The integrated DSP includes 6-band EQ, selectable 80Hz / 100Hz / 120Hz crossover frequencies, 20ms delay, feedback destroyer with dbx DriveRack technology, and limiter; Bluetooth Low Energy control via the JBL Pro Connect app enables remote adjustments of up to 10 speakers without physical access to the unit.
