JBL PRX915XLF

JBL PRX915XLF 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 15-inch 915SG woofer with a 3-inch voice coil and ferrite magnet. The system achieves 131 dB SPL @ 1m, providing sufficient headroom for mid-sized venues and outdoor events without distortion at typical operating levels.

Connectivity & Control

Dual combo inputs accommodate both XLR and 1/4-inch connections, while 2x XLR pass-through outputs allow daisy-chaining additional subwoofers or speakers. The 6-band parametric EQ, selectable 80Hz / 100Hz / 120Hz crossover frequencies, 20ms delay, and 0–12dB input gain provide comprehensive tuning options for different room and venue conditions; Bluetooth Low Energy control via the JBL Pro Connect app enables remote adjustments from anywhere in the venue without physical access to the unit.
